Findings include: 11.3 percent of the student population were identified as students with special needs; over 60 percent of students with special needs were served full-time in regular

The extension of these techniques to systems which include digital computers is not well developed, and there is little consensus among software engineering experts and safety experts on how to analyze such systems. One possible technique is to extend hazard analysis to include digital computer-based systems
