The Americans With
Disabilities Act, a monumental piece of legislation, was passed in 1990
for the purpose of reducing discrimination and making everyday life more
accessible to the over 43 million people in the United States with impairments.
Under the ADA, it is discriminatory to use selection criteria that tend
to screen out disabled individuals. Consequently, included in the legislation
is the requirement that disabled individuals be assessed using "reasonable
accommodations". This requirement has implications for all aspects
of the assessment process, including test development, selection, administration,
and interpretation (Fischer, 1994).
The goal of reasonable
accommodation in testing is to level the playing field by making it possible
for examinees with disabilities to understand and respond to what is being
asked (Fischer, 1994). When accommodations are provided, efforts also
must be made to insure that the test yields results that are valid, fair,
and reliable.
Test developers
and administrators have addressed the issue of accommodation in a number
of ways. What constitutes a "reasonable accommodation" depends
upon the nature of the disability and the circumstances of the assessment
(Geisinger & Carlson, 1995). Two broad methods of accommodation include
selecting alternative measures of assessment and modifying the measures
that are already available (Smith, 1998).
Smith (1998) advocates
the use of alternative measures that minimize the impaired skills whenever
feasible. For example, in testing the reading comprehension of a student
with expressive language problems, the examiner can consider which of
the already-normed available tests measure comprehension without involving
oral expression. An appropriate selection in this instance might be the
Peabody Individual Achievement Test-Revised (PIAT- R). It is incumbent
upon the examiner to be aware of the different instruments available to
measure specific abilities (Smith, 1998).
When there are no
alternative instruments, t e examiner must evaluate whether or not available
measures can be modified to accommodate the individual's particular disability
while still providing a valid measure of ability or skill. Modifications
can be made in test format, time limits, and test content. A change in
format refers to the use of a different medium or method to present the
same information, such as large print, Braille, or audiotape. Changes
in time limits often accompany changes in format, or may exist alone as
a specific modification. Changes in test content can include changing
individual test questions, changing the question-type, and changing or
deleting the measurement of a specific knowledge, skill, or ability.
Professional judgment
on a case-by-case basis is needed to determine the appropriateness of
a specific accommodation (Fischer, 1994). When considering which modification
to implement, the pros and cons should be evaluated, then the least intrusive
or disruptive one selected. Examples of modifications that are less likely
than others to affect the use of normative comparisons include: (a) providing
larger type, (b) substituting Braille for written words when speed is
not being measured, (c) using a pointing device to point to a response,
and (d) using a word processor for tests measuring written expression
(Smith, 1998). However, when any modification is made to a norm-referenced
test, results should be interpreted cautiously, recognizing that modification
can jeopardize validity.
If an individual
with a disability is assessed under standardized conditions without modifications,
professional judgment must again be used when- interpreting results. As
stated in The American Counseling Association (ACA, 1995) Code of Ethics
and Standards of Practice, counselors are to be "cautious in using
assessment techniques, making evaluations, and interpreting the performance
of populations not represented in the norm group on which an instrument
was standardized" (P. 13). Thus, it is important to consider whether
or not validation studies have been conducted using populations including
individuals with the same disability.
Some of the documents
providing guidelines for people who work with measurement and assessment
are in the process of revision. In particular, new guidelines for assessing
individuals with disabilities will be worded to insure compliance with
ADA. Among those documents under construction or revision are the Standards
for Educational and Psychological Testing, The Rights and Responsibilities
of Test-Takers, and the Multicultural Assessment Standards: A Compilation
for Counselors. Good assessment practice dictates being aware of current
professional guidelines, exercising professional judgment, and demonstrating
sensitivity to the challenge of insuring equity in assessment for all
individuals, including those with disabilities.
