Notes:
 California School Ratings (CSR) computes percentiles in this way:
 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.
 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.
 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.
 The combined Math+English weighted percentiles are put into an ordered list for the particular type of school (elementary/middle/high school/K12) and a percentilewithintheschooltype is calculated.
 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/K12) in California that have an equal or lower combined Math+English weighted percentile (from 1c 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.
 The CSR Rank is determined by a school's percentile in comparison to other schools of the same type in California (from 1d 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).
 Alternative Schools receive percentiles, but are not ranked
