While there has been considerable change in rank by size within the 100 largest school districts over time, the lists of school districts in 1994–95 and 2004–05 are similar. Only 12 of the 100 largest school districts in 1994–95 were not among the 100 largest school districts in 2004–05 (see table D-4 for a list of the 100 largest school districts in 1994–95).12
Between 1994–95 and 2004–05, the number of students in the 100 largest school districts increased by 10 percent, and the number of FTE teachers increased by 14 percent (table 4). However, while the numbers of students and teachers increased between these years, the proportion of the national total these numbers represent was essentially unchanged. For example, the 100 largest school districts included 23 percent of all students in both 1994–95 and 2004–05.
