| 1 Includes high school diploma recipients as well as other high school completers (e.g., certificates of attendance), but not high school equivalencies (e.g., GEDs). Total completers may be different than reported in the CCD state-level file. |
| 2 The grand total number of total completers for the entire set of the 100 largest school districts includes districts that reported diploma data but did not report other completer data. Individual districts, on the other hand, reporting diploma data but not other completer data are marked as missing. Therefore, the number of total completers for the entire 100 largest school districts is greater than the sum of the district-level total completer counts. |
| 3 The grades 9–12 dropout rate estimates the percentage of public high school students who left high school between the beginning of one school year and the beginning of the next without earning a high school diploma or its equivalent (e.g., a General Education Development (GED)) and do not meet any of the following exclusionary conditions: transfer to another public school district, private school, or state- or district-approved education program; temporary absence due to suspension or school-approved illness; or death. The grades 9–12 dropout rate is calculated by dividing the number of grades 9–12 dropouts by the grades 9–12 enrollment. Ungraded enrollment within each agency is redistributed across other grades in proportion to the graded enrollment. See appendix B for more information. |
| 4 Averaged freshman graduation rate (AFGR) is an estimate of the percentage of an entering freshman class graduating in four years. For 2006–07, it equals the total number of high school diploma recipients in 2006–07 divided by the average membership of the 8th-grade class in 2002–03, the 9th-grade class in 2003–04, and the 10th-grade class in 2004–05. Ungraded students were allocated to individual grades proportional to each state's enrollment in those grades. See appendix B for more information. |
| 5 Totals do not include districts where data were not available. |
| NOTE: Data include all 50 states, the District of Columbia, Puerto Rico, four outlying areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands), the Bureau of Indian Education, and the Department of Defense dependents schools (overseas and domestic). |
