A preliminary analysis of the 1973-74 national assessment of comprehensive health planning [P.L. 89-749, sections 314 (a) and (b)] agencies is reported. The analysis suggests that agency staff size and budget are more strongly related to high performance scores than is size of population served. Complete analysis of the 1973-74 assessment data was not possible because of time constraints; it is argued that plans should be made for detailed analysis of data from future assessments of planning agencies under P.L. 93-641 so that factors relevant to performance may be identified more precisely and incorporated into agency structure.
