(Vance & Plante, 1994) Selection of Preschool Language Tests: A Data-Based Approach
This article demonstrated that despite the 10 years that had passed between the publication of McCauley and Swisher (1984) and this article, the vast majority of commercially available norm-referenced tests did not provide psychometric measures deemed necessary in order to establish a test as valid.
(McCauley & Swisher, 1984) Psychometric Review of Language and Articulation Tests for Preschool Children
This was one of the first of many articles publishing research demonstrating the severe limitations of using commercially available child language tests when assessing children for speech and language disability.
