The National Center for Education Statistics (NCES) has employed its Fast Response Survey System (FRSS) to track access to information technology in schools and classrooms since 1994. This report presents key findings from the 2005 FRSS survey on Internet access in U.S. public schools and selected comparisons with data from previous FRSS Internet surveys. The 2005 survey, designed to update data on the issues addressed in 2003 and ask about a few new issues, covered the following topics: (1) school connectivity, including school and classroom access to the Internet, and types of connections; (2) student access to computers and the Internet, including student-to-computer ratio, the provision of hand-held computers to teachers and students, and laptop computers available for loan to students; (3) technologies and procedures to prevent student access to inappropriate material on the Internet; (4) teacher professional development on how to integrate the use of the Internet into the curriculum; and (5) use of Internet access to provide various opportunities and information for teaching and learning. Questionnaires for the survey "Internet Access in U.S. Public Schools, Fall 2005" were mailed to a representative sample of 1,205 public schools in the 50 states and the District of Columbia. The focus of this report is twofold: the national estimates for 2005, and statistically significant findings over time. The findings are organized to address the following issues: (1) school connectivity; (2) student access to computers and the Internet; (3) technologies and procedures to prevent student access to inappropriate material on the Internet; (4) teacher professional development on how to integrate the use of the Internet into the curriculum; and (5) use of the Internet to provide opportunities and information for teaching and learning. Appended are: (1) Technical Notes; and (2) Questionnaire. (Contains 21 tables, 2 figures, and 9 footnotes.)
