The index score is the number of college-level tests given at a school in the previous calendar year divided by the number of graduates that year. Also noted are the percentage of students who come from families that qualify for lunch subsidies (Subs. lunch) and the percentage of graduates who passed at least one college-level test during their high school career, called equity and excellence, (E&E). A (P) next to the school's name denotes a private school.
