Examined concurrent validity of several new and revised conceptual language measures. Administered Bracken Basic Concept Scale (BBCS), Boehm Test of Basic Concepts-Preschool Version (Boehm-PV) or Boehm-Revised, Peabody Picture Vocabulary Test-Revised (PPVT-R) to 99 preschool children attending kindergarten screening. BBCS correlated significantly with PPVT-R, both correlated significantly and comparably with Boehm-PV and Boehm-Revised. (Author/NB)
