The Study Group on Pre-Collegiate Education Quality Indicators was formed to determine means of obtaining information on elementary and secondary educational quality within and across states. Two papers: "State-by-State Comparisons of Student Achievement" (Robert L. Linn) and "The Effectiveness of American Education" (Eva L. Baker), along with meeting reports and ancillary material are presented in this document. State and local school administrators encounter public demand for thorough data on the quality of schools, allowing comparisons with data from other states and districts and with their own historical records. The study attempted to: define the content domain of the quality assessment program, relate the definition and score reporting systems to the validity of inferences based on state-by-state comparisons, measure student achievement and teacher quality, and examine the proposed merger of the National Assessment of Educational Progress (NAEP) and the School and Staffing Surveys (SASS). Recommendations include: a complete merger of the questionnaires and samples from the NAEP and SASS should not be attempted in 1990; informing policy analysis should guide any possible merger; a subset of questions from SASS could be administered with the NAEP to enhance policy analysis; and a 3- or 4-year cycle for SASS data collection should be considered.
