How is the WASI Scored?

The WASI-II (Wechsler Abbreviated Scale of Intelligence) is initially scored by converting the test taker’s raw score into a scale score. The scale score represents a common scale that allows for a quantitative comparison between a population of students. From there, the scale score is transformed into a composite score. For example, a composite score on the WASI-II could look like a numerical value of “90-109”. Traditionally, this score represents ‘average” performance. Additionally, on the tester’s scoring sheet, they will also likely see a score labeled percentile ranking (PR). This score demonstrates how the test taker scored against his or her peers. For example, if there is a 70 in this region then the individual will know that they scored better than 70 percent of the other test takers.

Standard Score Ranges for the WASI

“Superior” Performance: 130 and beyond. Individuals who score in this range are considered to be in the superior or “gifted” range.

“Very High” Performance: 120-129. Individuals who score in this range as classified as performing at a high level.

“Bright Normal” Performance: 110-119.

“Average”: 90-109

“Low Average”: 80-89

“Borderline Mental Functioning”: 70-79

The WASI provides a brief measure of cognitive ability. It can be used to screen for intellectual giftedness, assess cognitive functioning, or to identify learning difficulties.
