Admissions page |
The same schools ranked by college outcomes, with tuition and deadlines, are on the Los Angeles County private high schools page; tuition for every California private school is ranked on the tuition page.
Each exam entry is read from the school's own admissions page and shown only where the school posts one; the wording in "What the school says" is the school's, lightly shortened, and the source link is that page. Test dates and deadlines are as posted for the season the school's page describes and may change; a deadline already past is omitted. A school with no entry here did not state an exam on the pages we read. The list excludes nonclassroom-based online schools and schools the California Department of Education records with no 12th grade.
