1 Reporting states totals include any of the 50 states and the District of Columbia that reported all data elements.
2 The national estimate of 75.0 percent for 2003–04 does not include data from two states with missing diploma counts: New York and Wisconsin.
3 The national estimate of 73.2 percent for 2005–06 does not include data from two states, Pennsylvania and South Carolina, which did not report data, and the District of Columbia, for which reporting standards were not met. This is an important consideration when comparing the 2005–06 and 2006–07 national rates. Removing these states and the District of Columbia from the 2006–07 national counts results in a national rate of 73.7 percent, while prorating the 2006–07 rates to estimate the District of Columbia, Pennsylvania, and South Carolina data results in a 2005–06 rate of 73.4 percent.
4 In 2007–08, Maine reported 1,161 diplomas that were awarded to students attending private high schools that received a majority of their funding from public sources. These 1,161 diplomas were included in Maine and the reporting states counts but were not included in the averaged freshman graduation rate (AFGR) calculations for the state and for the reporting states totals. The diploma counts used to calculate the AFGR for Maine and for the reporting states were 13,189 and 2,964,125, respectively.
5 New Hampshire included homeschooled students in reported membership in 2000–01. This could inflate the denominator for the AFGR in 2002–03, 2003–04, and 2004–05 slightly.
NOTE: The averaged freshman graduation rate (AFGR) is an estimate of the percentage of an entering freshman class graduating in 4 years. For 2007–08, it equals the total number of diploma recipients in 2007–08 divided by the average membership of the 8th-grade class in 2003–04, the 9th-grade class in 2004–05, and the 10th-grade class in 2005–06. Ungraded students were allocated to individual grades proportionally to the reported enrollments by grade.
