This compilation of data was originally published in April 1981 as part of the Rochester City School District's preliminary three-year planning document. As the document's database, it reviewed several aspects of District instruction and operation including enrollment, student achievement and attainment, attendance, student mobility, and school holding-power. These data became the research base upon which the District's three-year plan was founded and from which its recommendations for improvement were developed. This volume, the 1982-83 database, expands the scope of last year's compilation and improves its format and content. As in the original volume, data are presented longitudinally, e.g. the reading and math achievement of District students over the past eight years, or the graduation rates among seniors for the past five. When possible, information on city schools has been described in the frame of reference of statewide or national research. Recommendations developed last year in the preliminary document are currently represented in several planning initiatives directed to improving District instruction and services. A list of these projects and an executive summary of the preliminary document have been included in this volume. (Author/BW)
