Secondary Division Courses

Unlike many other summer programs, ATDP offers courses that focus on acquisition of deep knowledge in a single topic. Secondary Division students are invited to immerse themselves and gain expertise in a subject that interests them. Some ATDP classes are designed to accelerate students through high school curricula. While ATDP does not provide credit for its courses, many high schools accept our recommendation of credit and will list ATDP classes on their transcripts.

With so many different courses to choose from, it is sometimes difficult for students to find the course that is just right for them! Read on for details about our tiered Writing & Literature classes, accelerated Mathematics program, AP classes, and applying for more than one course.

  Schedule & Size

ATDP offers courses that meet either two or three days each week. Most run the full six weeks of the Secondary Division (June 17 - July 26), though a small number of 5-unit classes run on unique four-week schedules.

Classes generally have a cap of 20 to 24 students. The low teacher-to-student ratio, as well as the counseling and administrative staff support, ensure instruction of the highest quality.

Units Meetings per week Length School workload equivalent
5 varies 6 wks. 1 semester (90 days)
5 3 (MWF) 4 wks. 1 semester (90 days)
10 3 (MWF) 6 wks. 2 semesters (180 days)


An ATDP course requires a serious time commitment. Students should expect to spend between three and ten hours preparing for each class meeting. The average number of hours of homework to expect per class meeting is listed below each course description and new students especially should expect to be spending time on homework that is at the upper end of the range provided.




ATDP recommends credit, but only the student’s school may grant credit for an ATDP course. Only courses that have been placed by the high school on the student’s high school transcript can be used to meet college entrance requirements. We mail a grade report to a student’s school upon the student’s request and only when credit is recommended. Any report that does not carry a credit recommendation is mailed only to the student’s home. (See Final Evaluations.)

ATDP recommends high school credit for students who have demonstrated mastery of a course with a grade of A or B. For grades of C and below, we assign a Pass or No Pass mark with no credit recommendation. ATDP courses can be considered for honors-level credit. Advanced Placement courses at ATDP are identified as such in their titles and should also carry appropriate credit.

Please check with your principal or guidance counselor before applying if credit is a concern.



In addition to its regularly scheduled courses, ATDP offers through its Explorations program a selection of optional classes, workshops, and trips.
