Tests for assessing learning and attentional disorders in adults

In order to determine reasonable and appropriate academic accommodations for students with learning and attentional disorders, Rhodes College requires a summary of instruments used to make the diagnosis and the recommended accommodations. This summary must include evaluation results from diagnostic interview, aptitude testing, achievement testing, and information processing.

When selecting a battery of tests, it is critical to consider the technical adequacy of instruments, including their reliability, validity and standardization on an appropriate norm group. Tests used to document eligibility must be technically sound and standardized for use with an adult population.

The following list of approved testing instruments is provided as a helpful resource, but is not intended to be definitive or exhaustive.

Aptitude/Cognitive Ability

  • Wechsler Adult Intelligence Scale-III
    (WAIS-III)
  • Woodcock-Johnson-III-Tests of Cognitive Ability
  • Kaufman Adolescent and Adult Intelligence Test
  • Stanford-Binet IV

The Slosson Intelligence Test-Revised and the Kaufman Brief Intelligence Test are primarily screening devices that are not comprehensive enough to provide the kinds of information necessary to make accommodation decisions.

Academic Achievement

  • Woodcock-Johnson-III - Tests of Achievement
  • Wechsler Individual Achievement Test (WIAT)
  • Scholastic Abilities Test for Adults (SATA)
  • Stanford Test of Academic Skills (TASK)

Or specific achievement tests such as:

  • Nelson-Denny Reading Test
  • Stanford Diagnostic Mathematics Test
  • Test of Written Language- 3 (TOWL-3)
  • Woodcock Reading Mastery Tests-Revised

Specific achievement tests are useful instruments when administered under standardized conditions and interpreted within the context of other diagnostic information. The Wide Range Achievement Test- 3 (WRAT-3) is not a comprehensive measure of achievement and therefore it is not useful if used as the sole measure of achievement.

Information Processing

  • Wechsler Adult Intelligence Scale-III (WAIS-III) subtests
  • Woodcock-Johnson-III-Tests of Cognitive Ability
  • Wide Range Assessment of Memory and Learning- 2nd Edition
  • Detroit Tests of Learning Aptitude- 3 (DTLA-3)
  • Detroit Tests of Learning Aptitude-Adult (DTLA-A)

These and other relevant instruments that assess information processing abilities are considered acceptable.

Assessing LD and ADHD

There are many excellent diagnosticians in the Memphis area who are able to perform psychoeducational assessments for learning disorders (LD) and diagnose and treat attention deficit disorders (ADHD).
