What Makes the WABC Different
Online Qualitative Response Analyzer
Enter data from a child's record form(s) and analyzer will automatically generate a summary of the basic concepts that the child identified correctly. The Response Analyzer will not calculate normative data (standard scores, etc). They produce qualitative reports to help establish intervention goals.

Who May Administer the WABC
Childhood teachers, special educators, and speech-language pathologists. It is recommended that only educators and professionals skilled in test administration and scoring, interpret the results and create intervention plans for their students.
Valid And Reliable
The WABC is a valid and reliable assessment instrument. For the standardization, the population sample included 1200 children from the United States and closely resembles 2000 U.S. Census data. Test-Retest correlations were very good with r = .93 for Level 1 Total Score and r = .92 for Level 2 Total Score. Inter-rater reliability was also high (.99). In comparing the WABC to the Boehm-3 Preschool and the Boehm-3, we found that both tests examine similar skills (Level 1 Total Raw Scores, Pearson's r = .69 and Level 2 Total Raw Scores, Pearson's r = .74).
