California sets statewide minimum course requirements for high school graduation and explicitly allows each school district to add requirements of its own. Irvine families need to track two standards at the same time: the state minimum and the requirements of Irvine Unified School District (IUSD). Where the two differ, the district requirements govern.
State Minimum Requirements
The California Department of Education lists the following minimum course requirements for grades 9 to 12:
| Subject | Years | Notes |
|---|---|---|
| English | 3 years | — |
| Mathematics | 2 years | Must include 1 year of Algebra I |
| Science | 2 years | Must include biological and physical sciences |
| Social Science | 3 years | Includes United States history and geography; world history, culture, and geography; and one semester each of American government and economics |
| Visual or performing arts, world language, or career technical education (one of the three) | 1 year | — |
| Physical Education | 2 years | — |
Two new requirements phase in by graduating class: one semester of Ethnic Studies, which applies to students graduating in the 2029-30 school year and later, and one semester of Personal Finance, which applies to students graduating in the 2030-31 school year and later. Students currently in middle school will fall within the scope of both requirements.
Districts May Add Requirements
The California Department of Education page states that the governing board of each local educational agency may add local requirements above the state minimum. This means graduation requirements differ from district to district within the same state. For the specific IUSD credit requirements, years required in each subject, and graduation standards, see the course and course selection pages for each school in the IUSD High School Guide; the course catalog each school publishes for the current year is the authority.
Graduation Requirements Are Not College Admission Requirements
This is the point that most needs to be clear. The state minimum graduation requirements and the University of California A-G subject requirements are two separate standards, and the latter is higher:
- English: graduation requires 3 years; A-G requires 4 years.
- Mathematics: graduation requires 2 years; A-G requires 3 years, and 4 years are strongly recommended.
- World language: for graduation, arts or career technical education can substitute; A-G requires 2 years of the same language.
A student who schedules courses to meet only the minimum graduation requirements can graduate without difficulty and still be ineligible to apply to the University of California. For an item-by-item explanation of A-G, see UC A-G Requirements Explained.
Three Key Checkpoints
First course selection in grade 9: The schedule chosen this year determines how much room remains over the next three years. A late start in world language or mathematics is difficult to make up later.
End of grade 10: By this point, it should be clear whether the student is on track simply to graduate or to meet A-G with room to spare. Any gap can still be adjusted at this checkpoint.
Course selection for grade 11: This is the last substantive opportunity to adjust. A missing requirement discovered in grade 12 can usually be made up only through summer courses or community college, and not every institution accepts those courses.
EDUBUS Recommendation
In the view of EDUBUS advisors, treating graduation requirements as the starting point for planning is not enough; course plans should be built backward from the requirements of target colleges. For most Irvine families, this means scheduling courses from grade 9 according to the years A-G recommends rather than the state minimum. For how courses map to grade levels, see Academic Enrichment Programs; for the checkpoints in the mathematics sequence, see The IUSD Secondary Mathematics Pathway, Explained.
