The LAC-3 is an individually administered, norm-referenced assessment that measures an individual's ability to perceive and conceptualize speech sounds using a visual medium. The LAC-3 also measures the cognitive ability to distinguish and manipulate sounds, which success in reading and spelling requires. All items on the test were evaluated using both conventional item analysis and differential item functioning analysis. An all-new audio CD demonstrating correct pronunciation and administration of test items is provided with the complete test kit.

Features of the LAC-3:

• Syllables have been extended from four phonemes to five
• Three subtests: Counting Syllables (Multisyllables), Tracking Syllables (Multisyllables), and Phonemes (Multisyllables)
• More validity studies

Provides percentile ranks, standard scores, and age/grade equivalents.
