This profile presents and summarizes available information about the quality of data from the five surveys that comprise the SASS, along with background material on the survey design and procedures for the following: (1) School Survey; (2) School Administrator Survey; (3) Teacher Demand and Shortage Survey; (4) Teacher Survey; and (5) Teacher Followup Survey. After an introduction, the report contains a section for each of the surveys covering frame development and sample selection, data collection and associated errors, and data processing and estimation. Each chapter also includes a section on evaluation of estimates. A final chapter discusses principal sources of error in the SASS surveys. Three exhibits and 37 tables illustrate the discussion and describe survey responses. (SLD)
