The recommendations of the National Academy of Sciences (NAS) panel are critiqued from a perspective of broad educational policy and legal influence. The report and the accompanying background papers are endorsed with general acceptance of problem identificaion and formulation. However, the report is challenged for recommendations that are too narrowly conceived, raising questions as ro viability of implementation. Specific issues addressed include treating disproportionate placement as a symptom versus problem, legal and professional policy barriers to implementing the report's recommendations, and the role of courts in resolving scientific disputes and programatic concerns.
