Results are presented of an onsite review of data gathered in 1971 by the Consolidated Program Information Report (CPIR), a survey instrument designed to fill the data needs of the Office of Education and state education agencies in relation to federally funded elementary and secondary education programs. This validation and error analysis of CPIR data was undertaken to examine the existence of both systematic and random errors in data reported on the CPIR forms; to suggest changes in procedures, forms, concepts, and instructions; and to identify the needs for further research in validity study areas. In the beginning sections of the study the methodology is described, and the analysis of the case study materials that were collected during site visits is presented, including a discussion of commonalities and trends across local education agencies (LEAs) and states. Chapter 4 presents an analysis of the discrepancies found between the data collected in the study and those originally submitted by the LEA. Chapter 5 contains a series of recommendations for changes in the CPIR instruments, procedures, and instructions. The reasons for the recommendations are documented and the impact on the CPIR data-collection effort is discussed both in terms of ease of collection and data accuracy. (Author/MLF)
