  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. Many ATDP courses now count toward UC and CSU college entrance requirements.

  About SD Courses

  Types of Courses

Secondary Division courses can help meet a variety of scholastic goals as diverse as its pool of applicants. Some aim to help middle school students to transition to high school topics, or high school students to college-level study. Others are equivalent to full-year high school or Advanced Placement curricula, offering the potential for students to accelerate through more advanced levels in a subject.

See Selecting a Course to learn about the varieties of courses in detail.

  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 22 – July 31), though a small number 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 academic and administrative staff support, ensure instruction of the highest quality.


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 self-study to expect per class meeting is provided in 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.



  Documenting Coursework

Secondary Division students take on a substantial commitment in completing a half year or full year of coursework in only 4-6 weeks. We congratulate students on their accomplishment and offer the following guidelines for recording and reporting ATDP coursework.

A-G College Entrance Requirements

Some ATDP courses are approved to satisfy A-G subject requirements for entrance to University of California (UC) and California State University (CSU) campuses. Students who take A-G approved courses at ATDP may report those courses on their college applications and count them toward the subject requirement. See the UC admissions website or CSU admissions website for details regarding A-G subject requirements. ATDP staff are happy to talk with families or counselors who have questions regarding ATDP’s A-G course list.

Information about which courses meet an A-G requirement is included in the online course catalog.

Final Evaluation & Grade

Upon completing a Secondary Division course, ATDP students will receive a final evaluation from their instructor. Printed on official UC bond paper, this document can be sent to schools as proof of course completion. It includes the instructor’s narrative of the student, final letter grade, and course load equivalent. ATDP will send one copy home in August, and if authorized by you, one copy to a selected school at no charge.

Transcripts & Credit

ATDP cannot provide a transcript for any of its courses, and the final evaluation is not an acceptable substitute for a high school transcript. Students interested in high school course credit should speak with their high school counselor or principal, and ATDP welcomes conversations with school staff regarding any questions about our program. Middle school students are not generally eligible for credit, but in some cases (as in our accelerated math courses), students may submit ATDP coursework to their schools for placement into more advanced courses.



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