This article describes efforts to examine the validity of a screening process that provides objective data for multidisciplinary team meetings where consideration is being given to teacher referral of a student for assessment and possible placement in special education. In this study, the accuracy with which this process, called Problem Validation Screening (PVS), identified students needing an eligibility assessment was examined. All first and second grade students at a participating school were administered several screening instruments. Students who met screening criteria on any of the screening instruments, and/or who were referred by their teachers, were exposed to a more intensive package of assessment activities termed the "Criterion Assessment" along with two commonly used achievement tests (Iowa Test of Basic Skills and Woodcock-Johnson Psychoeducational Battery-Revised). Predictive power estimates are reported for PVS to quantify the accuracy and utility of PVS as a screening device. (Contains 2 footnotes, 4 tables, and 1 figure.)
