United States Department of Education, Adjusted Cohort Graduation Rates

Description:

The adjusted four-year cohort graduation rate (ACGR) is the number of students who graduate in four years with a regular high school diploma divided by the number of students who form the adjusted cohort for the graduating class. The graduating class cohort is adjusted by adding any students who transfer into the cohort and subtracting any students who exit the cohort (transfer, death etc.) after the beginning of 9th grade. ACGR is reported for all students in a graduating cohort and student subgroups including major race and ethnic groups, limited English proficient, disability status and economically disadvantaged status.

In order to protect student privacy, EDFacts applies suppression of data for very small student groups and “blurring” of data for medium sized groups. Data is suppressed for student groups less than 5. For medium sized student groups (between 6 and 300), data is provided in value ranges (e.g., Less than 20% or 70-74%). The size of the value range varies and is determined based on the size of the student group or subgroup being reported. Due to the value ranges varying based on student group size and in order to allow for broader comparison across school districts of different sizes, PolicyMap generalized reported values into wider value ranges for certain districts. For example, a district with an ACGR value range of 85-90% in the source data will be displayed as 80%-90% in PolicyMap.
