‡ Reporting standards not met.
NOTE: Teachers include traditional public and public charter teachers who taught departmentalized classes to students in any of grades 10–12, or grade 9 and no grade lower. Each main assignment includes several subfields. Under science and social science any of several subfields are examined in detail. These subfields are not inclusive of all subfields in the subject and, therefore, do not sum to the broad field total. "Major in main assignment" includes all teachers, regardless of whether the major was earned within or outside the school/college of education. Majors in main assignment are credited if they were earned at the bachelor's degree level or higher. Detail may not sum to totals because of rounding.
