Academic Performance Index (API) Scores

Numeric Index
A numeric API score ranges from a low of 200 to a high of 1000. The interim statewide API performance target for all schools is 800. A school's growth is measured by how well it is moving toward or past that goal.

An API score is calculated for all students in a school as well as numerous API scores for each subgroup at the school (such as by race, English Learner Status, students with disabilities, and socioeconomic disadvantaged pupils).

Rankings
The API Statewide Rank score ranks a school with all schools in California based on API score, while the API Similar Schools score ranks a school with 100 other schools in the state with similar demographic profiles (including parent education level, poverty level, student mobility, student ethnicity).

Each rank ranges from 1 to 10, with a score of 10 meaning that the school's API fell into the top 10%.
