This report is one in a series of needs assessment publications that comprise the first phase of PROJECT DESIGN, an ESEA Title III project administered by the Fresno City Unified School District. The purpose of this study was to develop an achievement analysis model and to analyze achievement of students in the Fresno City Schools with reference to potential causal factors influencing achievement. Achievement data consisted of comparisons among the various achievement and aptitude data available from both State and local testing program. Three sets of geographical distributions of achievement were developed--for elementary grades, junior high schools, and high schools. Pertinent socio-cultural-economic factors and staffing resource program components were compared with the achievement data to determine probable causal factors. Although family income level, proportion of probationary teachers, ethnic majority, geographic location, and aptitude scores are correlated with achievement scores, the study does not provide material that would support direct cause and effect conclusions.
