About School Performance Maps

School Performance Maps provides a "bird's eye view" of public school performance in California.

Performance Data

School performance data is from the California Department of Education, Academic Performance Index. The 1-10 numbers represent the statewide rank of the school, from lowest to highest. On this site, the ranking is the rounded average of the rankings from the last 3 years of API Base reports. Schools must have a valid API Base state rank in at least 2 of the last 3 years to be ranked here.

Geographic Data

Locations of most schools are from latitude and longitude information ("geocodes") included in the National Center for Education Statistics data file. Other school addresses are from the California School Directory data file or were geocoded using geocoder.us, Google Maps, and Yahoo Maps. Accuracy of locations varies. Where multiple schools have the same address, some of the marker locations are adjusted slightly to reduce overlapping. You may need to zoom the map in to see markers that could be hidden behind others. Proximity of a residential address does not indicate inclusion in a school's attendance area; contact the local school district for attendance eligibility information.
