Diagnostician / Evaluator Qualifications
The assessment and diagnosis of specific learning disabilities must be conducted by a qualified
professional who has had comprehensive training and direct experience with an adolescent and
adult LD population. This evaluation should be done by a trained and certified and/or licensed
psychologist, learning disabilities specialist/diagnostician, or educational therapist. This type of
evaluation can be done by appropriate public school personnel and/or individuals in private practice.
It is not considered appropriate for professionals to evaluate members of their families.

Diagnosis / Verification of the Learning Disability (LD)
The assessment report must contain a diagnosis of specific LD (i.e. DSM-4). Nonspecific diagnoses
(i.e. learning styles, learning differences, academic problems, slow reader, and test anxiety) in and of
themselves do not constitute a learning disability. The report should use direct language in the
diagnosis with support of specific test results or clinical observations, and provide a need for
services based on current levels of functioning in an educational setting. This type of evaluation can
be done by appropriate public school personnel and/or individuals in private practice.

Diagnostic Testing Guidelines
  • Appropriate diagnostic testing should include the following:
  • Current Information. Diagnostic assessment and/or re-evaluation should be current within
    three years (particularly achievement testing).
  • Comprehensive Battery. A battery of more than one test and/or sub-tests within a diagnostic
    testing instrument.
  • Aptitude/Cognitive Ability Measurement. At least one instrument to measure aptitude or
    cognitive ability. This should be a complete intellectual assessment with all sub-tests and
    standard scores reported.
  • Academic Achievement Measurement. At least one measure of current achievement in each
    of the basic skill areas of Reading, Written Language, and Math.

  • Information Processing Measurement. Specific areas of information processing (e.g., short and long term memory, sequential
    memory, auditory and visual perception/processing, processing speed, executive functioning/fluid reasoning, and motor ability)
    should be assessed.

Suggested Diagnostic Evaluation Instruments
The following list is not intended to be all-inclusive or to limit assessment in other areas that may be pertinent to the individual, such
as vocational interests and aptitude, etc. The instruments listed below are routinely used and generally widely accepted by
professionals qualified in administering and interpreting such diagnostic evaluations. These guidelines are meant to provide specific
information with respect to the minimum areas that should be assessed in order to verify the diagnosis and to determine appropriate
academic accommodations.

Aptitude/Cognitive Ability Assessment Instruments:
  • Woodcock-Johnson Psycho-Educational Battery--III (WJ-III): Tests of Cognitive Ability is the preferred instrument. A report of the
    results, scored according to norms based on grade, is most appropriate for post-secondary students. Specific grade
    equivalent scores, standard scores, and SD Difference scores for each test and test cluster administered, and/or a copy of the
    "Compuscore" computer printout to accompany the diagnostic report, would be acceptable and useful information.
  • Woodcock-Johnson Psycho-Educational Battery-- Revised (WJ-R): Tests of Cognitive Ability is also a preferred older
    instrument. A report of the results, scored according to norms based on grade, is most appropriate for post-secondary
    students. Specific grade equivalent scores, standard scores, and SD Difference scores for each test and test cluster
    administered, and/or a copy of the "Compuscore" computer printout to accompany the diagnostic report, would be acceptable
    and useful information.
  • Woodcock-Johnson Psycho-Educational Battery-- Revised (WJ-R): Tests of Cognitive Ability is also a preferred older
    instrument. A report of the results, scored according to norms based on grade, is most appropriate for post-secondary
    students. Specific grade equivalent scores, standard scores, and SD Difference scores for each test and test cluster
    administered, and/or a copy of the "Compuscore" computer printout to accompany the diagnostic report, would be acceptable
    and useful information.
  • Wechsler Adult Intelligence Scale- 3 (WAIS-3) is also a preferred instrument. Verbal IQ, Performance IQ, Full Scale IQ, and all
    sub-test scores should be included.
  • Wechsler Adult Intelligence Scale-Revised (WAIS-R) is also a preferred older instrument. Verbal IQ, Performance IQ, Full Scale
    IQ, and all subtest scores should be included.
  • Stanford-Binet Intelligence Scale (4th ed.)
  • Kaufman Adolescent and Adult Intelligence Test
Academic Achievement Assessment Instruments:
  • Woodcock-Johnson Psycho educational Battery - Revised or III: Tests of Achievement
  • Wechsler Individual Achievement Test (WIAT)
  • Scholastic Abilities Test for Adults (SATA)
  • Stanford Test of Academic skills
  • Woodcock Reading Mastery Tests - Revised
  • Nelson Denny Reading Test
  • Test of Written Language - 3 (TOWL-3)
  • Stanford Diagnostic Mathematics Test

Information Processing Assessment Instruments:
  • Woodcock-Johnson Psycho educational Battery - III : Tests of Cognitive Ability
  • WAIS-3 Subtests
  • WAIS-R Subtests
  • Detroit Tests of Learning Aptitude - 3 (DTLA-3)
  • Detroit Tests of Learning Aptitude - Adult (DTLA-A)

Diagnostic Evaluation Report Guidelines:
The report should include a clear statement of the learning disability and the rationale for this diagnosis. Individual learning styles and
learning deficits do not necessarily, in and of themselves, constitute a learning disability.

Tests Administered and Test Scores:
The names of the tests used in making the diagnosis and the specific scores from these tests should be included in the report. Grade
level scores, standard scores, and percentile scores are helpful in understanding the rationale behind the diagnosis and in
recommending appropriate support services.

Recommendations/Accommodations:
Recommendations should include specific suggestions for reasonable academic-related accommodations, which might be
appropriate at the post-secondary level. These recommendations should be based on the diagnostic evaluation results and should
be supported by the diagnosis. When appropriate, additional recommendations for specific learning strategies, academic support
services, and any other suggested treatment procedures would also be useful.

Evaluator/Diagnostician Identifying Information:
Diagnostic reports should include the name, signature, license number (if applicable), title, address, and phone number of the
evaluator(s) and the date(s) of testing.

A Comprehensive Assessment Battery and the Resulting Diagnostic Report should include the following:
  • Evaluator Information: Name, signature, license number (if applicable), title, address, and phone of the evaluator/s.
  • Evaluation Date/s: Dates of testing; the evaluation must have been completed within the previous three years.
  • Tests Administered and Scores: Names and specific scores of diagnostic instruments used in making the diagnosis.
  • Diagnostic Interview: A summary of relevant information regarding the student's academic history and learning processes.

Assessment Battery: A comprehensive battery should include:
Aptitude/Cognitive Testing: Intellectual ability with all sub-tests and standard scores.

Academic Achievement Testing:
Comprehensive achievement in reading, mathematics and oral and written language skills reported in both grade level and standard
scores.

Information Processing Testing:
Ability scores in short and long term memory, auditory and visual processing, processing speed, and reasoning skills.

Clinical Summary:
Indicate how evaluator has ruled out alternative explanations for academic problems, how assessment score patterns reflect
presence of LD, how LD constitutes a substantial limitation to learning or other major life activity, degree to which learning is impacted
by the LD, rationale for specific accommodations needed.

Recommendations:
Specific suggestions for reasonable academic-related accommodations based on diagnostic evaluation results and supported by the
diagnosis.
