The Wiig Assessment of Basic Concepts^® (WABC^®) is a unique, norm-referenced assessment that evaluates a child's understanding and use of basic concepts.

Use the WABC^® to:

• Create focused IEPs and intervention plans.

• Thoroughly assess basic concepts.

• Identify children in preschool and kindergarten who need "extra help" with basic concepts.

• Distinguish deficits in using basic concepts from deficits in understanding them.

• Further distinguish an inability to understand basic concept terms from deficits in auditory processing (following directions).

What Makes the WABC^® Different?

• There is no easel. Instead, the test presents an interactive storybook format. This gives you the opportunity to test the child in a setting that is quite natural to most children (looking at/reading a book).

• The WABC^® embeds concept pairs or related words in colorfully illustrated scenes. Instead of presenting each concept as an unrelated single word, the WABC^® assesses one of the concepts in a pair receptively (Which bear is big? Child points to big bear) and the other expressively (You showed me big. This bear is...Child says, "little." )

• The WABC^® contains two age-level tests. Level 1 - A Day at the Zoo is for preschool children ages 2;6 to 5;11 years, and Level 2 - A Day at the Park is for children in kindergarten and early elementary grades ages 5;0 to 7;11 years. For a more complete picture of strengths and weaknesses, you may administer BOTH levels to children between 5;0 and 5;11 years.

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).
