What is the purpose of an assessment of children who
are deaf or hard of hearing?
The education of children who are deaf or hard of hearing
is a complex process. Appropriate placement, mode through which they learn
best (auditory, visual, or tactile), curriculum, amplification, and decisions
about transition from service to service that families, schools, and individuals
make depend on reliable information. Assessment results should provide
decision makers with information from a variety of sources. The communication,
academic, intellectual, medical, and audiological characteristics of a
child combine to create an interconnected pattern of strengths and needs
that parents and teachers must translate into classroom goals and objectives.
When assessment information serves as the basis for planning of a child's
daily program, it serves its primary purpose. The most common purposes
for assessment of children who are deaf or hard of hearing include:
1. Establishing a baseline level of performance.
2. Determining an appropriate placement or change in
placement.
3. Measuring progress (including legally required assessment
such as three-year re-evaluations).
4. Suggesting solutions to identified problems such
as behavior, attention difficulties, or slow progress.
5. Developing goals and objectives when reviewing a
program.
A diagnostician who can administer a valid assessment
and provide results that serve the stated purpose of an evaluation must
have adequate experience with this low incidence population. Gaining that
experience, particularly in small school districts or rural special education
agencies, can be very difficult. Assessment needs can take many forms,
from administration of standardized tests in a clinical setting to classroom
observation. The population of children who are deaf or hard of hearing
is quite diverse. Children who are deaf and hard of hearing differ widely
in their home environments, the cause and extent of hearing loss, language
development history, and the existence of complicating factors (e.g.,
mental retardation, motor or visual limitations, learning difficulties).
Most diagnosticians are not likely to have repeated experience in the
assessment of such a range of individual differences.
What are some problems associated with assessment?
The following problems can also influence the accuracy
and usefulness of assessment results:
1. Diagnosticians may not have the credentials or experience
with the deaf population needed to obtain valid results or produce programming
recommendations. A degree in psychometry (i.e., administering tests) or
psychology, deaf education, or speech-language pathology does not ensure
that the examiner has the skills needed to evaluate children who are deaf
or hard of hearing.
2. In some cases, diagnosticians are unable to communicate
with their clients. A child who is deaf or hard of hearing may use one
of several different communication languages or modalities. In the United
States these include: speech and listening, cued speech, American Sign
Language, a form of Manually Coded English, or a combination of any of
these. Limited fluency in only one English sign system or American Sign
Language may not be sufficient for an examiner to see any signing child
without an interpreter qualified to use the child's language. In addition,
the inexperienced speaking examiner may be unaware of the special communication
requirements of children who are deaf or hard of hearing and who are communicating
through spoken language.
3. The results of tests that are normed on or compared
to children who hear may not be valid for the child who is deaf or hard
of hearing, yet tests normed on students who are deaf or hard of hearing
say little about a child's actual progress toward established academic
and linguistic standards, especially when compared to classmates who are
mainstreamed.
4. A child's performance on an isolated task presented
by a stranger will rarely be comparable to that child's performance in
a classroom during a familiar activity.
5. Interpretation of test results depends on the knowledge
and experience of the evaluation team. Professionals who are very familiar
with a child may be overly generous, while those with insufficient information
may erroneously estimate the child's capabilities.
6. Results of various assessment types must be viewed
together. Understanding academic test performance depends on knowing communication
and intellectual assessment results. Behavior can be evaluated adequately
only if the psychologist knows the child's language and academic limitations
in his or her current placement. When individual assessments are carried
out in isolation, integrated results may not be available before important
decisions are made.
7. The multidisciplinary team (a team of individuals
with different areas of expertise) developing an individualized educational
program (IEP) based on assessment results sometimes does not include professionals
trained in education of children who are deaf or hard of hearing or may
use consultants in that field who are unfamiliar with the child being
assessed, which may lead to inappropriate or unrealistic goals and objectives.
Who does an assessment?
Ideally, the examiner for a child who is deaf or hard
of hearing child will:
1. Have the credentials to administer the formal tests
used in the assessment (for example, teachers for academic testing, speech-language
pathologist for communication, psychologist for intellectual, adaptive
behavior, and behavioral assessment).
2. Be familiar with the effects of hearing loss on test
and classroom performance.
3. Have experience with intervention as a teacher, speech-language
pathologist, or psychologist/counselor for children who are deaf or hard
of hearing.
4. Be able to communicate effectively with the child,
parents, and teachers during and after the assessment, with or without
an interpreter.
5. Have access to previous assessment information and
educational history relating to the child being tested.
What are the benefits of assessment?
Through lack of assessment, some deaf students have
reached high school age without learning to read, have developed behavior
problems through long-term frustration with inappropriate placement, or
have been inadequately challenged. An appropriate assessment can avoid
these problems by:
1. Validating or questioning the concerns of parents
and teachers about a child's performance level or progress.
2. Indicating areas of strength and weakness for further
diagnostic teaching or observation.
3. Identifying and helping to resolve conflicts among
parents and professionals by suggesting solutions based on the best interests
of the child.
4. Providing information that can be directly incorporated
into a student's (IEP).
What are the limitations of assessment?
Assessment is a tool that helps parents and professionals
provide a child who is deaf or hard of hearing with the best possible
educational and developmental opportunities. However, assessment by itself
will not accomplish that purpose, and limitations of assessment include
the following:
1. Assessment cannot specifically pinpoint age and grade
levels comparable to those assigned to normally hearing children. Age
equivalent and grade equivalent scores on tests have very limited relationship
to the daily classroom performance of a child who is deaf or hard of hearing.
2. The usefulness of assessment results is often limited
by the qualifications of the examiners or by missing information. Appropriate
recommendations based on assessment data depend on the examiner's ability
to interpret the results.
3. Assessment cannot replace, only supplement, daily
observation and parent/teacher judgment.
What questions need to be asked during the assessment?
Examiners and parents need to ask:
1. What are the diagnostic questions at the time of
this evaluation? Why is it being done and how will the results be used?
2. How did environmental factors, the child's behavior,
and the child's familiarity with the examiner influence the reliability
and validity of this assessment?
3. How do the findings of other diagnosticians fit with
these test results to create a comprehensive picture of the whole child?
4. What are the resources available in the child's
community to implement the recommendations from this assessment?
