1Averaged freshman graduation rate (AFGR) is an estimate of the percentage of an entering freshman class graduating in 4 years. For 2004–05, it equals the total number of diploma recipients in 2004–05 divided by the average membership of the 8th-grade class in 2000–01, the 9th-grade class in 2001–02, and the 10th-grade class in 2002–03.
2First-time 9th-graders were estimated as the average of student membership in grades 8, 9, and 10 in 3 consecutive years.
3Reporting states totals include the 50 states and the District of Columbia for which data were available.
4AFGR was more than 100 percent. Transfers in and out of public schools during high school can distort the AFGR for relatively small populations.
NOTE: Ungraded students were allocated to individual grades proportional to each state's enrollment in those grades.
