MARK ANSWERS IN TEST BOOKLET
|
|
In
some situations, the typical multiple-choice
fill-in-the-bubble separate sheet
response format may not be an appropriate way for a
student to complete a test. The mark answers
in test booklet accommodation may be
necessary for some students to demonstrate what
they truly know and can do. This accommodation
allows students to respond to test items directly
in the test booklet rather than on a separate
answer sheet.
Explanation
Burns
(1998) suggested that if a student does not
understand the bubble-task, is not able
to record answers using a bubble format, or has a
mobility or coordination problem, marking answers
in the test booklet might be an effective
accommodation. Bubbling-in answers on a separate
answer sheet requires adequate student attention to
ensure that the intended item is being marked. It
also requires adequate motor coordination. If a
student does not have these prerequisite abilities,
his or her test performance may not reflect what
the test was intended to measure.
State
Use
Of the 48 states with
statewide assessment programs, 28 allow the mark
answers in test booklet accommodation. Five
additional states allow it on a portion, but not
all, of the required state assessments (Thurlow et
al., 2000).
Empirical
Research
Four empirical studies were
identified that examined the effects of the
mark answers in test booklet
accommodation. Three of these studies showed no
significant difference between performances of
students receiving this accommodation and students
completing the test under a standard response
mode.
Rogers (1983) conducted a
study of this accommodation with 8- to 16-year-old
students with hearing impairments taking a
multiple-choice spelling test. Results indicated
that the separate answer sheet was a valid
assessment strategy, and that the two methods had
similar degrees of reliability. In other words, the
standard and accommodated test formats functioned
similarly for this group of students. Tolfa-Veit
and Scruggs (1986) looked at differences in number
of items marked outside the box for
fourth grade students with and without learning
disabilities. Results indicated that students with
and without learning disabilities had similar
percentages of items marked outside of the
necessary area. Students with learning disabilities
were found to complete significantly fewer items
than students without learning disabilities in the
specified time period; however, the two groups did
not differ in the percent of items they answered
correctly. Tindal, Heath, Hollenbeck, Almond, and
Harniss (1998) similarly studied this accommodation
with fourth grade students in special and regular
education. In this study, students completed
statewide reading and math tests in both
accommodated and non-accommodated conditions.
Results indicated that there were no significant
differences between testing response formats for
either group of students (those in regular
education and those in special
education).
In a study by Mick (1989), a
modified test format including marking
answers in test booklet was found to result
in lower scores for students with educable mental
handicaps and students with learning disabilities.
A reading test was administered to these students
under both a modified format (large print,
unjustified lines, and writing answers directly in
test booklet) and a standardized format. Although
these results may suggest that marking answers in
the test booklet puts students at a disadvantage,
it is not clear which aspect(s) of the modified
version accounted for changes in
performance.
Overall, there is no
empirical support for this accommodation if the
criterion is increased test scores. Test scores for
students taking the test with and without this
accommodation are similar; only one study suggested
otherwise.
Controversy
Separate answer sheets help
to facilitate the scoring process. Research has
shown students to score similarly both with and
without this accommodation. It might be argued,
therefore, that the accommodation of marking
answers in test booklets is unnecessary. However,
the research has failed to address the needs of
students with specific motor impairments, as well
as those students with attention problems that
might lead them to mis-mark answers when using a
separate answer sheet. Because of this, this
accommodation still seems warranted in certain
situations with certain students.
Recommendations
- This accommodation should
be allowed for students with motor coordination
problems that hinder their ability to respond
appropriately in a standard test format.
Furthermore, this accommodation should be
favored above other response accommodations
(e.g. dictated response to a scribe) because it
is less likely to result in test
bias.
- More research should be
done on this accommodation, especially involving
students with attention problems and physical
impairments.
- If a student does not
know how or is not attentive enough to mark
answers appropriately on a separate answer
sheet, this accommodation should be provided;
however, it may be that the student should be
taught how to appropriately use the standard
bubble sheet format for later testing purposes
(Burns, 1998).
- There should be ample
space in the test booklet for the student to
respond when providing this accommodation (CEC,
2000).

READ ALOUD TEST ITEMS
|
|
Reading aloud a test to a
student is an accommodation frequently used by
students with learning disabilities. Students with
physical or visual impairments may also benefit
from the oral reading accommodation; however, it
has been suggested that students with visual
impairments should be tested with Braille or
large-print when possible (Phillips, 1994). The
read aloud accommodation generally refers to having
a teacher or aide read test directions, test items,
and test reading passages to students. Although
this accommodation is often used in combination
with other equipment (e.g., computer, video,
cassette tape, etc.), for the purposes of this
analysis, focus will be placed on read aloud
accommodations as provided by test proctors and
teachers.
Explanation
Reading is a prerequisite
skill for demonstrating skills in a variety of
academic areas. For instance, completing math word
problems requires that students know how to read
the questions. However, the intent of such an item
may be to test math skills rather than reading
skills. For this reason, it appears necessary to
allow a read aloud accommodation for students with
reading disabilities. In this way, students
true abilities can be manifested on the test
without error that is due to an inability to read
quickly or accurately.
State
Use
Of the 48 states with
statewide assessment programs, 4 states allow the
read aloud accommodation without limitations. One
state prohibits its use, and 30 states allow it
under certain conditions. The states that impose
limitations on this accommodation generally allow
it only on certain sections of the assessment, such
as in the math, science, social studies, and
writing sections, and prohibit its use on the
reading sections (Thurlow et al., 2000).
Survey
Research
The 64 teachers responding to
the Gajria et al. (1994) survey of 100 teachers
generally favored the read aloud accommodation. A
total of 90.6% of the respondents were aware of the
read aloud accommodation, 79.7% reported using it
in their classrooms, and 89% thought that providing
this accommodation maintained the integrity of the
test. It was ranked 7th of 32 accommodations in
terms of ease of use, and 5th in terms
of effectiveness.
The Jayanthi et al. (1996)
survey responses from 401 of the 708 general
education teachers to whom survey were sent
indicated that reading test questions to
students was an easy accommodation to make.
They also indicated that it was helpful
to very helpful to use. Of the teachers
that responded, 67.9% reported using this
accommodation in their classrooms.
Hollenbeck et al. (1998)
found that 56% of the 166 responding teachers (of
633 surveyed) had correct knowledge about the
accommodation entitled read math text.
A total of 21% reported using this
accommodation.
Empirical
Research
Oral
reading accommodation for math tests. Nine
studies looked at the effects of the oral reading
accommodation on math test scores. Five of these
studies tested the hypothesis that the oral reading
accommodation should differentially boost the
scores of students with disabilities compared to
students without disabilities. Three of these
studies found that students with learning
disabilities benefited significantly more from the
accommodation than students without disabilities
(Fuchs, Fuchs, Eaton, Hamlett, & Karns, 2000;
Tindal, Heath, Hollenbeck, Almond, & Harniss,
1998; Weston, 1999). Although Johnson (2000) found
that students with learning disabilities did
differentially benefit from the accommodation, the
increase in scores was not statistically
significant due to a small sample size. Johnson
(2000) also found that orally reading the test
items had no differential effects for good versus
poor readers among non-disabled
students.
Further support on using this
accommodation for students with learning
disabilities is warranted from additional findings
by Tindal et al. (1998). Tindal et al. (1998) found
that even the lowest achievement-ranked students in
general education did not benefit significantly
from the oral reading accommodation. According to
these findings, the oral reading accommodation
appears to be a valid accommodation for students
with learning disabilities. Calhoon, Fuchs, and
Hamlett (2000) studied a sample of only students
with learning disabilities, and found that
providing a reader on a math test significantly
increased scores. They also studied a computer read
aloud accommodation, and found that this
accommodation also increased scores of students
with learning disabilities. No significant
difference in scores was found between teacher-read
and computer-read accommodations.
Other studies have looked at
the read aloud accommodation in terms of overall
test functioning. Pomplun and Omar (2000) found
that a proposed two-factor model (writing and math
factors) fit the data for all groups of students on
a fourth grade math test, including students with
learning disabilities receiving the read aloud
accommodation, students with learning disabilities
not receiving the accommodation, and students
without disabilities. This further suggests that
the read aloud accommodation is appropriate for
students with disabilities on math tests.
Additionally, Bielinski, Thurlow, Ysseldyke,
Freidebach, and Freidebach (2001) found that
although there were a few items that displayed
differential item functioning for accommodated
students on a statewide math test, overall, the
accommodated version appeared to be measuring the
same construct as the non-accommodated test for
students without disabilities. In a similar study,
Lewis and Green (1999) found there to be relatively
few items displaying DIF for the accommodated group
on a math test; however, no reference group of
regular education students was provided in the
study.
In contrast, Meloy, Deville,
and Frisbie (2000) found that the read aloud
accommodation increased the scores of both learning
disabled and non-learning disabled students on math
and science sections of the Iowa Tests of Basic
Skills. They argued that the read aloud
accommodation changed the construct being measured
for most students relative to what is measured
under standard conditions.
For the most part, the oral
reading accommodation for math tests appears to be
supported by research. However, the findings of
Meloy et al. (2000) suggest that more research
support is needed to validate the use of this
accommodation
Oral
reading accommodation for reading tests.
Concern has been expressed regarding the use of the
oral reading accommodation on reading tests.
Phillips (1994) suggested that this accommodation
results in the substitution of listening
comprehension for reading comprehension, and
therefore greatly alters what the test measures.
Burns (1998) argued that the oral reading
accommodation for reading tests undermines test
validity, and could lead to students not getting
necessary services.
Five studies on the use of
the read aloud accommodation for reading tests were
identified. Tippets and Michaels (1997) examined
the factor structure of reading and language arts
tests for students receiving the read aloud
accommodation alone and in combination with other
accommodations (e.g., read aloud + extended time,
read aloud + dictated response, etc.), and compared
this to the factor structure of the tests for
non-accommodated students. Results indicated no
difference between the structures, which suggests
that the same underlying construct was being
measured.
Contrary to this finding,
Meloy et al. (2000) found that the read aloud
accommodation benefited both learning disabled and
non-learning disabled students on several sections
of the Iowa Tests of Basic Skills, of which the
greatest impact was found on the reading sections
of the test. This suggests that the accommodation
changes what the test measures, therefore is
invalid. Bielinski (2000) also suggested that the
read aloud accommodation changed the construct that
statewide reading test intended to measure. He
found numerous items displaying differential item
functioning (DIF) when compared to results for
students in regular education. However, there were
also several DIF items for low performing students
in regular education. Lewis and Green (1999) found
few DIF items for accommodated students in a
similar study; however, the study did not provide a
comparison group of students without
disabilities.
Finally, Barton and Huynh
(2000) conducted a study of errors made by students
with disabilities receiving the read aloud
accommodation on a high school reading test. Their
analysis suggested that there may be some items
that are particularly difficult for students
receiving the read aloud accommodation, such as
items that include an index of entries or
references that are difficult for students to
listen to and remember if they are not skilled in
following along as the proctor reads.
Clearly, more research needs
to be done on the oral reading accommodation to
determine how it affects what the test
measures.
Controversy
Research has primarily
supported the use of the read aloud accommodation
for students with disabilities on math tests.
However, great concern has been expressed about the
validity of using this accommodation on reading
tests, and limited research has addressed this
issue. Additionally, it is not always clear what
the read aloud accommodation entails; in some cases
students may be allowed to ask the reader to
re-read certain sections, and in other
cases students have the test read only once and
must rely on auditory memory in answering the
questions (Burns, 1998). Administering this
accommodation in large groups of students can
complicate things further; students may require
different amounts of time to complete items,
requiring the reader to adjust his or her pace
accordingly. Concern is also evident in whether
students should be given a copy of the test to
follow along or if they should simply listen to the
test being read. Some students may benefit from
following along, whereas it may pose as a
distraction for others (Burns, 1998). Finally,
readers must be careful not to display inadvertent
cues such as changes in voice inflection when
correct answers are being read. Students may easily
recognize these subtle hints, which may in turn
alter the meaning of test scores. Overall, it
appears that differences in how the read aloud
accommodation is administered may have important
effects on test scores.
Recommendations
- The read aloud
accommodation should be offered to students for
whom it is determined will benefit from this
accommodation on tests not specifically designed
to measure reading achievement.
- More research needs to be
done on using the read aloud accommodation on
reading and language arts tests.
- Decisions should be made
on an individual basis about whether the student
can follow along when reading the test, or
whether he or she should only listen to the test
being read (Burns, 1998).
- In order to best reflect
the non-accommodated condition, students should
be allowed to ask the reader to re-read certain
sections of the test.
- It is best to administer
this accommodation individually to effectively
accommodate each students
pace.
- Students using the oral
reading accommodation should be allowed
approximately twice the normal amount of time to
complete the test (Burns, 1998).
- Readers should be trained
in how to effectively administer this
accommodation (proper reading speed, avoidance
of inappropriate voice inflection, etc.). They
should know the pronunciation of words on the
test and practice reading it in a
straightforward and clear manner prior to test
administration (CEC, 2000).

READ/REREAD/SIMPLIFY/CLARIFY TEST DIRECTIONS
|
|
A variety of adaptations are
frequently made in how test directions are
communicated to students. Directions may be read
aloud or paraphrased, additional examples may be
given, or the student may be allowed to ask to have
directions repeated. Frequently, this accommodation
is included along with the read aloud accommodation
for the remainder of the test. This accommodation
appears to be most appropriate for students with
reading-related disabilities.
Explanation
In order for students to
demonstrate what they know and can do on a test,
they must have a good understanding of what the
test requires them to do. A small misunderstanding
in test directions can cause students to complete
an entire test incorrectly. In general, tests do
not intend to measure how carefully a person can
follow directions. This accommodation helps to
facilitate the understanding of test directions so
that students can demonstrate their true knowledge
and skills.
State
Use
Of the 48 states with
statewide assessment systems, 31 allow some form of
the read/reread/ simplify/clarify directions
accommodation (Thurlow et al., 2000). One state
prohibits this accommodation, and four other states
have limitations on its use. In one state that
limits its use, clarifying directions is
prohibited. In another state, the accommodation is
allowed only on certain subtests.
Survey
Research
This accommodation has been
the subject of several surveys. The earliest was by
Gajria et al. (1994), who surveyed 100 teachers and
received responses from 64. They found that 90.6%
of those surveyed were aware of the read test
directions and items accommodation, 79.7%
reported using it in their classrooms, and 89%
thought that it maintained the integrity of the
test. It was ranked 7th of 32 modifications in
terms of ease of use, and 5th in terms
of effectiveness.
Jayanthi et al. (1996)
received surveys from 401 of 708 general education
teachers. Results indicated that of the 24
accommodations studied, give individual help
with directions during tests was rated as
easy to very easy to
provide. It was ranked first in helpfulness, and in
terms of how many teachers used the accommodation
(84.7% of the teachers who responded indicated that
they used the accommodation).
Lambert et al. (1996)
received responses from 121 of 171 teachers
surveyed. Allow a proctor to rephrase test
questions ranked sixth among several
accommodations in terms of the percentage of
teachers who had provided the accommodation in the
past. Also, the average rating of willingness to
provide this accommodation was 4.1 on a 1-5 rating
scale, 5 being very willing to
provide.
Hollenbeck, Tindal, and
Almond (1998) surveyed 633 regular and special
educators, of which 166 responded. They found that
51% of the teachers who returned surveys had
correct knowledge about the clarify
directions accommodation, and 16% reported
using this accommodation.
Empirical
Research
Very limited research on this
accommodation was identified. Elliott, Kratochwill,
and McKevitt (2001) included support with
understanding test directions as part of a
package of accommodations to students in a study of
the effects of testing accommodations for students
with and without disabilities. Several students
without disabilities and all students with
disabilities in this study were given an
individualized accommodation package determined to
be appropriate by their teachers. Another group of
students without disabilities was provided a
standard package of testing accommodations, which
included support with understanding test
directions as well as other accommodations
(e.g., help reading words, verbal encouragement,
extra time). Finally, one group of students without
disabilities was not provided any accommodations.
Accommodation packages were found to have positive
effects for a large percentage of students with
disabilities (63.4%), a medium percent of students
without disabilities who received the teacher
recommended packages (42.9%), and a smaller percent
of students without disabilities receiving the
standard package (20.0%). Because of the use of
multiple accommodations in this study, however, it
is difficult to determine the specific effects of
the support with understanding test
directions accommodation.
Controversy
Tests typically are not
designed to measure how well students follow
directions, but rather how well they read, write,
calculate, etc. Logically, this accommodation
should not change what the test measures. Teachers
and policymakers tend to agree that this is a valid
accommodation; overall, there is not much
controversy. However, further empirical support
should be sought. Furthermore, because this
accommodation is definitionally
diverse, it may be necessary to study its
different manifestations separately (e.g., reading
directions vs. simplifying directions).
Recommendations
- In general, test
directions should be written as simply and
clearly as possible on the test, thus avoiding
the need for much additional
clarification.
- When the purpose of the
test is not to test the ability to follow
directions, this accommodation should be
allowed.
- This accommodation should
always accompany the read aloud accommodation
unless the test measures reading decoding
skills.
- When clarifying test
directions, it is important for the test
administrator to clearly and accurately
communicate how the test is to be
completed.
- A set of guidelines
should be developed to indicate appropriate and
inappropriate procedures for this
accommodation.
- This accommodation may
require testing in a separate location in order
to avoid distracting other students (CEC,
2000).

TEST BREAKS
|
|
Students often are provided
breaks between subtests. In some circumstances,
students are not given breaks between subtests, or
the breaks they are given are very short. Rarely
are students given breaks within subtests. In this
summary, the test break accommodation
is defined as allowing students to take the test
with breaks when the normal administration of the
test does not include breaks. The test breaks
accommodation may provide students with various
disabilities the opportunity to demonstrate what
they truly know and can do on a
test.
Explanation
The use of magnification
equipment, tape recorders, and earphones can cause
fatigue, making frequent breaks a necessity (CEC,
2000). Also, students with attention problems may
have difficulty concentrating on a test for the
period of time that is typically expected of
students. Fatigue and lowered concentration levels
can limit students abilities to show what
they really know on a test. When provided with more
frequent or longer breaks, students with
disabilities can experience a break from
frustration and regain an optimal level of test
concentration.
State
Use
Of the 48 states with
statewide assessment programs, 28 allow the test
break accommodation. Five additional states allow
this accommodation under certain conditions. For
these five states, the accommodation is allowed on
only some of the statewide assessments, or is
allowed only between subtests (Thurlow et al.,
2000).
Survey
Research
No survey research was
identified that specifically addressed the test
breaks accommodation. One study, however, examined
the accommodation of testing over several sessions.
Hollenbeck, Tindal, and Almond (1998) surveyed 633
regular and special educators and received
responses from 166. They found that 45.2% of the
responding teachers had correct knowledge about
this accommodation, and 18% reported using this
accommodation.
Empirical
Research
No studies were identified
that specifically addressed the test breaks
accommodation. However, two studies were identified
that examined the use of a very similar
accommodation testing on multiple days.
DiCerbo, Stanley, Roberts, and Blanchard (2001)
studied the effects of two-day and three-day
administrations of reading comprehension tests on
the scores of 939 third-grade students. All
students completed a form of the Stanford 9 reading
comprehension test, and a second form of the same
test under either the two-day or three-day
condition. Students were not able to return to
previously completed test sections on the second or
third days, and the overall amount of time students
had to complete the test was equivalent. Results
indicated that participants scores were 12
scaled score points higher for the divided-time
administrations than for the one-time
administration (ES=.25). There was also a
significant time by reading comprehension ability
interaction (p < .001). Middle and low ability
readers experienced greater benefits from the
multiple day administrations than high ability
readers.
Walz, Albus, Thompson, and
Thurlow (2000) examined the effects of allowing
students to take a reading test over multiple days
versus one day. Participants were 112 seventh and
eighth grade students (48 students receiving
special education services, and 64 non-special
education students) taking the Minnesota Basic
Standards reading test. Under the one day
administration, students read and answered
questions for three reading passages; in the
multiple day administration, students read one
passage and completed the corresponding questions
each day for three days. Each student participated
in both administrations of the test. Results
indicated that a multiple-day test accommodation
did not enhance the test scores of students with
disabilities. Furthermore, students without
disabilities performed better under the one-day
administration.
Overall, it appears that more
research needs to address the test breaks
accommodation. No research was identified that
specifically studied this accommodation, and
studies of similar accommodations have differing
results. Perhaps the age of the students is a
factor (e.g., younger students may benefit more
from this accommodation).
Controversy
Test breaks are suggested to
provide students with disabilities a chance to
regain concentration in order to perform optimally
on tests. Furthermore, this accommodation does not
appear to significantly affect what is being
tested. However, no research has addressed whether
students with disabilities perform better when
provided the test breaks accommodation. It has been
suggested that breaks within subtests may distract
from the problem-solving rhythm a student has
developed (Burns, 1998) and interfere with
performance on a sequence of items (CEC, 2000).
However, breaks between subtests are suggested to
be beneficial, especially when students are being
administered a test individually (Burns, 1998). It
is clear that more research is needed to determine
whether the test breaks accommodation is
appropriate, and if so, how and when it should be
used.
Recommendations
- Test breaks between
subtests should be provided to students for whom
it has been determined will benefit from this
accommodation.
- Breaks within subtests
should be avoided, unless absolutely
necessary.
- Because it may be
possible for students to find answers to
previous test questions during breaks, students
should not be allowed to return to previously
completed test items following a
break.
- The test break
accommodation may require a separate setting
(CEC, 2000).
- Lengthened test breaks
may be necessary for some students (Burns,
1998).
- Test-developers should
take into consideration the age and the
sustained attention abilities of the students
who will be tested.
- More research needs to
address the use of this
accommodation.

SUMMARY
|
|
This report on the research
that has been conducted on the most frequently used
accommodations reveals that there are not yet
simple or conclusive answers to questions about the
effects of accommodations. Yet, there are some
trends. There were three accommodations included
here that more than 90% of the states allow without
limitations (Interpreter for Instructions, Large
Print Edition of the Test,
Read/Reread/Simplify/Clarify Directions). For these
three, the primary concerns relate to the quality
of the implementation of the accommodation and to
the alignment of the accommodation to specific
student needs.
The Read Aloud accommodation
is clearly the most controversial of the most
frequently allowed accommodations, with only four
states allowing it without limitations. The
research confirms this controversy, with results
for reading tests mired in concerns about fidelity
of implementation, validity issues, and logistical
concerns, even though use of Read Aloud generally
is supported for math tests.
It is important to continue
to document what the research tells us, and to
analyze the specific context of the studies, their
methodologies, and their findings. Doing so will be
facilitated by referring to NCEOs searchable
accommodations research database on its Web site
(http://education.umn.edu/NCEO/AccomStudies.htm).
