Psychometric review of language and articulation tests for preschool children.

Thirty language and articulation tests developed for use with preschool children were reviewed using ten psychometric criteria appropriate to norm-referenced tests. Half of the reviewed tests met no more than two criteria, and only three tests met over four criteria. Most frequently unmet criteria were those requiring empirical evidence of validity and reliability. Implications are drawn regarding the current status of norm-referenced language and articulation tests for preschool children.
