Graduation Rate Identification Criteria
Federal guidance requires that in addition to the five percent of schools identified as persistently lowest-achieving, schools in Tiers I and II be identified if the school’s graduation rate is below 60 percent over a number of years.
For this identification process, California employed the National Center for Educational Statistics (NCES) four-year completer rate for which we are approved to use until four years of longitudinal data are available through the California Longitudinal Pupil Achievement Data System (CALPADS). More information about the NCES four-year completer rate can be found in the 2009 Adequate Yearly Progress Report Information Guide located on the CDE Adequate Yearly Progress Web page [http://www.cde.ca.gov/ta/ac/ay/].
The NCES four-year completer rate was evaluated for schools in Tier I and Tier II. Any school with a high school graduation rate below 60 percent in each of the last four years was included in the list. (Note: To be consistent with the n-size approved in California’s Accountability Workbook, only schools with 100 or more valid scores in each of the last four years were included in the analysis.)
