Although prereferral intervention teams (PIT) are common in public schools, there is little and conflicting research to support them. The current article conducted an empirical meta-analysis of research on PITs by reviewing 72 articles. Results revealed a mean effect size of 1.15 for student outcomes and 0.90 for systemic outcomes. Implications for research and cautious suggestions for practice are discussed. (Contains 44 references and 1 table.) (GCP)
