The Wepman Auditory Discrimination Test assesses childrens ability to recognize differences between phonemes used in English speech. Because younger children are included in the norm sample, the ADT can be used for preschool and kindergarten screening as well as elementary school assessment.
Forty pairs of words are read out, and the child indicates, verbally or gesturally, whether the words in each pair are the same or different.
The entire test can be administered and scored in just 5 minutes.
The ADT offers norms based on a stratified national sample of approximately 2,000 children. It provides standard scores and percentile norms at half-year intervals for children between the ages of 4 and 8 years. The two alternate forms (Form 1A and Form 2A) have separate norms.
