In 2009-10, the North Carolina Department of Public Instruction was approved to include a five-year graduation rate as well as a four-year rate in determining if schools, districts, and the state made Adequate Yearly Progress (AYP) under the NCLB Act. This rate was based on the incoming 9th grade students of 2005-06. The denominator of the cohort remained the same for both the 2008-09 four-year and the 2009-10 five-year rate with an additional 296 graduates added to the numerator in the fifth year. The 2009-10 five-year district rate rose to 81.5% from a 2008-09 four-year rate of 78.4%. The subgroups with the largest increases were limited English proficient (9.8 percentage points), economically disadvantaged (7.8 percentage points), and students with disabilities subgroups (7.4 percentage points). Hispanic/Latino and Black/African American students had the largest rate increases among ethnic subgroups (6.6 and 5.5 percentage points, respectively).
