You may have read reports that North Carolina’s graduation rate for African-American students was “the third best in the country at 72.3 percent.”
The statistic came from the 2011 Diplomas Count report, an annual report published by Education Week. Education Week examined graduation rates from 1998 to 2008, so the 72.3 percent rate is a few years old.
2006: 60.4%2007: 61.4%2008: 62.7%2009: 63.2%2010: 66.9%
Rates reported in Diplomas Count are based on a Cumulative Promotion Index (CPI) based on promotion rates throughout high school and students’ earning a diploma. North Carolina reports four-year and five-year graduation rates using a cohort graduation rate that actually follows each individual student from ninth grade entry throughout high school. The four-year cohort rate is very similar to the rate calculated by Diplomas Count researchers. North Carolina is one of only four states with a reported cohort rate that is not inflated above that calculated by the EPE researchers. (Emphasis added.)
