This report is intended to give the reader an overview of the Schools and Staffing Survey (SASS) data for the school year 2003-04 through tables of estimates for public, private, and BIA-funded schools and their staff. The tables contain estimates from schools, teachers, principals, districts, and school library media centers for public, private, and BIA-funded schools, as applicable. All tables for public and private schools show breakdowns by school type (public schools: traditional or charter; private schools: Catholic, other religious, or nonsectarian), community type (urbanicity), school level (elementary, secondary, or combined), and student enrollment. Tables containing district reports show breakdowns by district size (number of schools in the district), community type (urbanicity), district K-12 enrollment, and the percent of K-12 students who were approved for free or reduced-price lunches. The following five sections illustrate what data are available in SASS by the type of respondent: Schools, Teachers, Principals, Districts, and Library Media Centers. A few examples of these data are then highlighted in each section for public respondents only. These highlights were not selected to emphasize any particular issue, and they should not be interpreted as representing the most important findings in the data. They are simply examples of the kinds of data that are available and can be compared. Tables 2-17 provide data as reported by schools on student characteristics, targeted services and programs offered, school organization, and school staffing and vacancies. Tables 18-26 provide data on teachers as reported by the teachers, including general characteristics, highest degree earned, teaching experience, salary, and hours worked in a typical week. Tables 27-32 include data on principals as reported by the principals, including general characteristics, highest degree earned, experience, salary, and hours worked in a typical week. Tables 33-42 provide school district data and comparable private school information when available, including teacher salary schedules, benefits and incentives offered, professional development for teachers and administrators, hiring criteria, student assessments, and graduation requirements. Tables 43-47 present data as reported by school library media centers on topics pertaining to the libraries such as staff qualifications, structure, and availability and acquisition of materials. Appendix A comprises standard error tables. Appendix B comprises methodology and technical notes. Appendix C is a guide to the analysis variables used in the tables of this report and is intended for researchers who obtain the restricted-use datasets for SASS. Appendix D is a glossary of terms.
