This report describes the validity and reliability studies done to standardize a preschool screening test developed for identification of articulation and language disorders. The test meets the need for a brief procedure which (1) identifies articulation and language disorders, (2) is not dialect bound and goes across cultural and regional differences in English, and (3) is standardized on a predominately black population. The test takes 5 to 8 minutes to administer and includes basic areas of vocabulary, articulation, and language. A failure in articulation and/or language indicates the need for a longer evaluation. The results of the short screening test are compared with the results of more extensive testing for 152 children enrolled in day care and Head Start type programs. Ages ranged from 2 1/2 to 5 1/2 years, with 25 children in each 6 month age group. Ninety-four percent of the time the screening either agreed with the evaluation (135 children) or gave a false positive (10 children), indicating that this test is an efficient and valid indicator of articulation and language disorders. Communication of results to school personnel and parents for effective follow up is discussed. Tables are included. A testing kit and manual are available. (Author/NH)
