  1. California School Ratings (CSR) computes percentiles in this way:
    1. For a given grade level, all Math scores are put into an ordered list and a percentile is calculated for each score, based its position in the list.
    2. For a given grade level, all English scores are put into an ordered list and a percentile is calculated for each score, based its position in the list.
    3. Math and English percentiles from (a & b above) are weighted, based on the number of students who completed each type of test, to create a combined Math+English weighted percentile for each school.
    4. The combined Math+English weighted percentiles are put into an ordered list for the particular type of school (elementary/middle/high school/K-12) and a percentile-within-the-school-type is calculated.
    5. How percentiles work: the school percentile is a number between 0 and 100 that reflects the percentage of schools of the same type (elementary/middle/high school/K-12) in California that have an equal or lower combined Math+English weighted percentile (from 1-c above). For example, a school in the 70th percentile would have a combined weighted percentile that was equal to or better than 70% of the other schools of the same type.
  2. The CSR Rank is determined by a school's percentile in comparison to other schools of the same type in California (from 1-d above). (1 is the worst, 10 is the best). Schools in the 90th percentile and above have rank 10, 80%-89.999% rank 9 and so on. A similar number of schools occupy each rank. * This rank is derived from data in the 2016 California Assessment of Student Performance and Progress (CAASPP).
  3. Alternative Schools receive percentiles, but are not ranked
