Timesaving joint scoring and reporting programs are also available to accommodate the links with the Wechsler cognitive scales.

WIAT®–II Scoring Assistant®
This efficient software automatically scores and reports the WIAT–II, identifying academic strengths and weaknesses; comparing performance to age- and grade-based norms; and providing error analysis by subtest to guide intervention planning. The WIAT-II Scoring Assistant works with the WISC-IV Scoring Assistant (sold separately) to obtain discrepancy scores.
