When determining a school’s 12th-grade cohort we look at the most recent school that a student indicated on their AP registration as the school they attend full time. Students are counted toward your school's Honor Roll metrics only if they are full-time enrolled students at your school. This means that when a student registered to take AP Exams, they indicated that your school was their primary attending school, and they have not since transferred schools or updated their attendance to a different school when taking an AP Exam.
If a student took AP Exams at your school in 11th grade, and then transferred out of your school prior to 12th grade and never took AP again at any school, then they will still be included in your AP dataset. However, if a student took AP Exams at your school in 11th grade, and then transferred out of your school prior to 12th grade and enrolled at a different school where they took AP then they would not be included in your 12th-grade AP cohort.
If a student is receiving instruction from a teacher at your school for a specific subject but does not attend your school full time, then they would not be included in your 12th-grade AP cohort count. If a student is attending your school full time, their entire AP Exam-taking history during high school is included in the data used to calculate the school honor roll. Note that exams taken prior to 9th grade are not included.
