Auditec Auditory Test Auditory Perception of Alphabet Letters

The Auditory Perception of Alphabet Letters© (APAL) test uses oral production of the letters of the alphabet. It is a closed-set of the 26 letters. Responses may be oral, by sign, or by pointing to a response board (supplied). The test consists of five forms; all 26 letters are used. Scoring is weighted by the proximity of the response to the phonetic content of the letter.

The APAL was developed for use with hearing impaired children for whom the more standard tests are unsuitable. Children may be unfamiliar with some of the pictured items on the WIPI, PSI, or NU-CHIPS, or some of the PBK-50 words may not be in the child’s vocabulary or the child’s speech may be unintelligible, or the materials may be too easy or uninteresting. In these cases, the APAL may prove useful. The administration time of the APAL is approximately 16 minutes.
