The problems identified in our debate had to do with our not having the technical knowhow to identify the causes of educational disadvantages and enumerate the children so disadvantaged without massive testing programs. The conferences provision allowing a number of local education agencies to participate voluntarily in experimental projects of the National Institute of Education may give us the experience we need to improve the formula in future legislation. The holdharmless provision for State education agencies programs for handicapped. migrant. and neglected and delinquent children is one of the provisions against disruptive change that make the report a solid one. Impact aid programs are to be gradually reformulated. This is a longoverdue move. but. according to the conference reports provisions. will be phased in so that school districts will not have to face immediate. drastic change.
