Brief: CCC Precalculus Validation Extended to 2028

The California Community Colleges Chancellor’s Office announced in memorandum ESS 26-67, dated October 13, 2026, that the validation timeline for prior-to-calculus pathways in science, technology, engineering, and mathematics (STEM) programs is extended by one year, from July 1, 2027 to July 1, 2028. As reported by EdSource on November 12, colleges begin building their 2027-28 course schedules this month. The extension concerns where the first mathematics course begins for Irvine students who pursue a STEM major at community colleges such as Irvine Valley College and Saddleback College.

Who Is Affected by the Precalculus Validation Extension

The precalculus validation extension affects students who pursue a STEM major at a California community college and plan to transfer to the University of California. The background is state law AB 1705: STEM students are in principle placed directly into STEM Calculus 1, and a college that offers a pathway of preparatory courses before calculus must demonstrate with local data that the pathway is effective.

The memorandum states that the extension applies automatically to all colleges and that the statutory requirements do not change. Four provisions affect students directly.

• Colleges must give STEM students timely access to STEM Calculus 1, with or without concurrent support.
• Students who have completed Integrated Math 4, Trigonometry, Precalculus, or an equivalent course may not be denied access to STEM Calculus 1.
• Placement uses high school transcript data as the primary basis and self-reported information when transcripts are unavailable; colleges may not require students to repeat coursework they have already passed.
• For a preparatory pathway that has not been validated, colleges may not require or recommend enrollment and must inform students that the course is optional and has not been shown to improve the likelihood of completing calculus. No more than two transfer-level courses may precede STEM Calculus 1.

What Irvine Transfer Students Should Do About the Precalculus Validation Extension

Confirm the highest mathematics course completed in high school. An Irvine high school student who has completed Precalculus or an equivalent course is entitled to enroll directly in STEM Calculus 1 at a community college. How the level of high school mathematics connects to college mathematics is explained in How Far to Take High School Math.

Treat preparatory courses as an option. Preparatory courses are not required. A student with a solid foundation who starts in STEM Calculus 1 saves the terms that preparatory courses would occupy; a student with a weaker foundation can first ask a college counselor about concurrent support.

Plan mathematics courses backward from the intended major. Transfer preparation for STEM majors starts with calculus, and the starting point of the first mathematics course affects whether the mathematics required by the intended major can be completed before transfer. Transfer data for the local college appear on the Irvine Valley College page; families who want a term-by-term course plan can learn about the EDUBUS Community College Transfer to UC planning service.
