Reynolds Intellectual Assessment Scales™/Wide Range Achievement Test 4-Discrepancy Interpretive Report (RIAS™/WRAT4-DIR)
Cecil R. Reynolds, Ph.D., Randy Kamphaus, Ph.D., and PAR Staff

Students who have discrepancies between their IQ scores and achievement test scores present a unique challenge to school psychologists and clinicians. The RIAS/WRAT4-DIR addresses this problem by providing and evaluating discrepancies between scores on the Reynolds Intellectual Assessment Scales (RIAS)/Reynolds Intellectual Screening Test (RIST) and on the Wide Range Achievement Test 4 (WRAT4). By comparing general ability levels as assessed by the RIAS to achievement levels as obtained by the WRAT4, the RIAS/WRAT4-DIR provides school psychologists with the information necessary for determining special education eligibility and the presence of specific learning disabilities in students.

Two types of scoring methodologies are used to derive the discrepancy scores and to evaluate the statistical significance of the score and its prevalence within the population. The simple difference method examines the difference between an obtained RIAS score and an obtained WRAT4 score. The predicted-achievement method uses the individual's obtained RIAS score to predict his or her performance on the WRAT4. It then examines the difference between the predicted WRAT4 score and the individual's obtained WRAT4 score. Using these methods, three types of discrepancy reports that contain a total of 40 discrepancy scores are generated by the software:

• RIST/WRAT4 Discrepancy Interpretive Report--Provides discrepancy scores and analysis between the RIST index score and each WRAT4 subtest/composite score (i.e., Word Reading, Sentence Comprehension, Spelling, Math Computation, Reading Composite).

• RIAS/WRAT4 Discrepancy Interpretive Report--Provides discrepancy scores and analysis between each RIAS Index score (i.e., VIX, NIX, CIX, CMX) and each WRAT4 subtest/composite score.

• RIAS/WRAT4 Total Battery Discrepancy Interpretive Report--Provides discrepancy scores and analysis between the RIAS Total Battery Index scores (i.e., TTB, TVB, TNB) and each WRAT4 subtest/composite score.

The RIAS/WRAT4-DIR Professional Manual Supplement provides normative data about the linking sample, which consisted of 410 participants ages 5-24 years and was reasonably matched to U.S. Bureau of the Census population data for gender, ethnicity, and educational attainment. The Professional Manual Supplement also provides overviews of the RIAS and the WRAT4, including original standardization information, descriptions of the two different scoring methods, and suggestions for the interpretation of the discrepancy scores.

The unlimited-use software generates discrepancy scores and interpretive reports that are based on a clinician's entry of an individual's raw scores and provides an efficient file handling system that enables the user to create client files where all protocols and report files for each client are managed.

The RIAS/WRAT4-DIR also is available as a combination product that includes the RIAS-IR and WRAT4-IR. Special pricing for Customers who have previously purchased scoring software for the RIAS and/or WRAT4 is available
