Figure 4. Averaged freshman graduation rates of public high school students, by state: School year 2003–04
— Not available.
1 The national estimate does not include data from two states with missing diploma counts: New York and Wisconsin. When the national estimate is adjusted to account for missing information for these two states by using the 2002–03 rates for these states, the adjusted national rate is 74.3 percent.
NOTE: The averaged freshman graduation rate provides an estimate of the percentage of public high school students who graduate with a regular diploma 4 years after starting 9th grade. The rate uses aggregate student enrollment data to estimate the size of an incoming freshman class and aggregate counts of the number of diplomas awarded 4 years later. The incoming freshman class size is estimated by summing the enrollment in 8th grade for one year, 9th grade for the next year, and 10th grade for the year after and then dividing by 3. The number of diplomas is the count of all diplomas awarded 4 years after a 9th–grade class started 9th grade. Ungraded students were allocated to individual grades proportionally to the enrollments by grade. See table 13 for more information about these state rates.
