Receptive & Expressive Testing The
WABC® groups 113 basic concepts in two sets: Level 1 and Level 2. Each Level assesses concept knowledge (receptive) AND use (expressive) across seven (7) categories:
- Color or Shape (Ex., red, square)
- Size, Weight or Volume (Ex., short/tall, big/little)
- Distance, Time or Speed (Ex., far/near, slow/fast)
- Quantity or Completeness (Ex., none/all, less/more)
- Location or Direction (Ex., behind/in front)
- Condition or Quality (Ex., hot/cold, wet/dry)
- Sensation, Emotion, or Evaluation (Ex., bad/good)
Who May Administer the WABC®?
Childhood teachers, special educators, and speech-language pathologists may administer the WABC®. We recommend, however, 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 US 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 with an Alpha of .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).
