Academic Performance Index (API)

The API is a numeric index (or scale) ranging from a low of 200 to a high of 1000 that reflects a school's performance level based on the results of statewide testing. The API was established by California's Public Schools Accountability Act (PSAA) of 1999. Results from the Standardized Testing and Reporting (STAR) Program and the California High School Exit Examination (CAHSEE) are used in calculating the API. The statewide API performance target for all schools is 800. A school's growth is measured by how well it is moving toward that goal. A school's base year API is subtracted from its next year's growth API to determine how much the school grew in a year.

Adequate Yearly Progress (AYP)

The No Child Left Behind (NCLB) Act of 2001 is federal legislation that established a new definition of Adequate Yearly Progress (AYP) for all schools, districts, and the state, beginning with the 2002-03 school year. All schools and districts are required to meet all AYP criteria in order to meet federal NCLB accountability requirements. A school or district is identified for Program Improvement (PI) if it does not meet AYP criteria for two consecutive years within specific areas. A school or distict is eligible to exit PI if it makes AYP for two consecutive years.

CELDT (California English Language Development Test)

The California English Language Development Test (CELDT) is given as an initial assessment to newly enrolled students whose primary language is not English, and as an annual assessment to English learners enrolled in kindergarten through grade twelve in California’s public schools.

The CELDT has three purposes:

  1. To identify students who are limited English proficient
  2. To determine the level of English language proficiency of students who are limited English proficient
  3. To assess the progress of limited English proficient students in acquiring the skills of listening, speaking, reading, and writing in English
