The University of California (UC) sets mandatory high school course requirements for applicants, known as the A-G subject requirements. They specify how many years a student must complete in each of seven subject areas, and a student who does not meet them is not eligible to apply. For students in Irvine, these requirements are not something to consider only in the application season. They are a constraint that applies from the first course selection in grade 9.
The seven requirements
The following comes from the A-G requirements page on the University of California admissions website.
| Area | Subject | Years required | Official recommendation |
|---|---|---|---|
| A | History | 2 years | Must include 1 year of world history, cultures, or historical geography, and 1 year of U.S. history, or one-half year of U.S. history and one-half year of civics and American government |
| B | English | 4 years | College-preparatory English with frequent writing and reading of classic and modern literature |
| C | Mathematics | 3 years | The university states that 4 years are “strongly recommended” |
| D | Science | 2 years | Must cover two of biology, chemistry, and physics; a 3rd year is recommended |
| E | Language other than English | 2 years (same language) | A 3rd year is recommended |
| F | Visual and performing arts | 1 full year | One course chosen from dance, music, theater, visual arts, or interdisciplinary arts |
| G | College-preparatory elective | 1 year (2 semesters) | May be a course approved specifically for G, or an additional course beyond the A through F requirements |
Two differences in wording deserve attention. Mathematics carries a three-year requirement with four years “strongly recommended”; science and language carry a two-year requirement with a third year “recommended.” In actual admission decisions, meeting the recommended number of years is close to the default level for competitive majors, especially in science, engineering, and business.
Grade and GPA thresholds
The University of California requires a minimum GPA of 3.0 for California residents and 3.4 for nonresidents, and no A-G course may carry a grade lower than C. In practice, a D in an A-G course means that course does not count toward the requirement. The student must repeat it or satisfy the requirement with another course; the effect is not simply a slightly lower average.
What this means for Irvine students
High school graduation requirements in Irvine Unified School District (IUSD) and the A-G requirements are not the same standard. California’s minimum state graduation requirements are three years of English, two years of mathematics, and two years of science, while A-G requires four years of English, three years of mathematics, and two years of science covering two disciplines. A student whose schedule follows only the minimum graduation requirements may graduate on time and still not be eligible to apply to the University of California.
Three areas where problems often arise:
- Language other than English: The requirement is two years of the same language. Middle school courses that the district recognizes as high school level can count, but a student who switches languages starts over from the beginning.
- Continuity in mathematics: The three-year requirement refers to college-preparatory mathematics. Students on the accelerated track usually complete it by grade 11, but leaving grade 12 without a math course can affect the evaluation for some majors, which is why the university recommends four years.
- Visual and performing arts: The requirement must be met with one full-year course in the same subject. Two half-year courses in different subjects do not satisfy it.
Which courses at each school are approved for A-G is determined by that school’s course catalog for the current year. Course maps for the five Irvine public high schools appear in the Irvine Unified School District high school guide.
EDUBUS recommendations
In the view of EDUBUS, A-G is a floor, not a goal. Students who treat it as a checklist often take only the required number of years in mathematics and science, and these two areas are the main basis on which competitive majors evaluate course rigor. EDUBUS advisors recommend planning the schedule in grade 9 around the required years plus the officially recommended years, leaving room for AP and honors courses in grades 11 and 12. Each step of the math pathway is described in The IUSD Secondary Mathematics Pathway, Explained, and the progression of skills across four years of English is described in High School Reading & Writing Seminars.
