Reports and data files are based on test results of the standardized Testing and reporting (STAR) Program,the California High School Exit Examination (CAHSEE), and the California Alternate Performance Assessment (CAPA).

Local education agencies (LEAs), on behalf of their schools, have the right under the federal No Child Left Behind (NCLB) Act of 2001 to appeal the Adequate Yearly Progress (AYP) or Program Improvement (PI) status of their schools. 

Reported data may change due to a number of factors, such as:

• School districts correcting errors in demographic data
• The California Department of Education (CDE) reviewing & identifying additional data errors
• Application of safe harbor calculations
• Schools identified as having incomplete data
