California Homeschool Law: The Private School Affidavit
California homeschool law is governed by Education Code § 48222. Under this statute, parents who wish to homeschool their children operate as a private school by filing a Private School Affidavit (PSA) with the California Department of Education each year. The PSA must be filed between October 1 and October 15. Once filed, your family's home qualifies as a private school, you are the administrator, and you issue the transcript.
California places no state-mandated assessment requirements on homeschoolers and sets no required credit minimums for homeschool graduation. You define your own standards, curriculum, and graduation criteria. This gives California families tremendous flexibility, but it also means the responsibility for creating a credible, well-documented transcript falls entirely on you.
What California Colleges Require: The a-g Sequence
The University of California (UC) and California State University (CSU) systems use the a-g subject requirements as their college-prep benchmark. While these requirements were designed for public school students, homeschoolers applying to UC or CSU campuses are expected to demonstrate equivalent preparation. Private colleges and out-of-state universities generally review the same subjects, so meeting the a-g sequence is the most widely accepted college-prep standard for California homeschoolers.
The a-g requirements total 15 required credits across seven subject areas:
-
a. History / Social Science , 2 credits (1 year World History, 1 year US History or Government/Economics)
-
b. English , 4 credits (composition and literature, all four years)
-
c. Mathematics , 3 credits minimum (Algebra I, Geometry, Algebra II at minimum; 4 years recommended)
-
d. Lab Science , 2 credits (at least 2 of Biology, Chemistry, and Physics; 3 years recommended)
-
e. World Language , 2 credits (same language; 3 years recommended)
-
f. Visual / Performing Arts , 1 credit (dance, drama, music, or visual arts)
-
g. College-Prep Elective , 1 credit (an additional year in any a-g subject area, or an approved elective)
Credit Targets for College-Bound CA Homeschoolers
Because California sets no state minimums, most college-bound families use the a-g sequence as a floor and build toward 22–24 total credits over four years. Here is how a typical college-prep California homeschool transcript breaks down:
| Subject Area | a-g Minimum | College-Prep Target |
|---|---|---|
| English / Language Arts (b) | 4.0 credits | 4.0 credits |
| Mathematics (c) | 3.0 credits | 4.0 credits |
| Lab Science (d) | 2.0 credits | 3.0 credits |
| History / Social Science (a) | 2.0 credits | 3.0 credits |
| World Language (e) | 2.0 credits | 3.0 credits |
| Visual / Performing Arts (f) | 1.0 credit | 1.0–2.0 credits |
| College-Prep Elective (g) | 1.0 credit | 1.0 credit |
| Additional Electives | No fixed minimum | 3.0–6.0 credits |
| Total | 15 credits | 22–24 credits |
Required Elements of a Complete California Transcript
Use this checklist when building your transcript. Every item below should appear on the final document:
-
Student informationFull legal name, date of birth, address
-
Private school nameThe name you filed on your PSA (e.g., “Golden State Academy” or “The Martinez Home School”)
-
Courses organized by yearGroup by grade (9th, 10th, 11th, 12th) or by academic year, note which a-g subject each course satisfies
-
Grades and grade pointsLetter grade and numeric grade point value; include your grading scale
-
Credits per courseStandard full-year course = 1.0 credit; semester course = 0.5 credit (Carnegie Unit standard)
-
Cumulative GPA, weighted and unweightedInclude the scale used (e.g., A = 4.0; Honors +0.5; AP/PSEO +1.0)
-
Total credits earned
-
Expected graduation date
-
Parent signature and titleSign as “Principal” or “Administrator” using the school name on your PSA, this is standard practice and legally appropriate under Ed. Code § 48222
GPA Calculation for California Homeschoolers
GPA is calculated the same way regardless of state: multiply each course's grade points by its credit value, sum all those products, and divide by the total number of credits. The standard 4.0 scale applies to most courses. Honors-level courses typically add 0.5 points and AP or dual enrollment courses add 1.0 point to produce a weighted GPA.
For UC and CSU applications, the system calculates its own UC-calculated GPA from courses taken in 10th and 11th grade using only a-g eligible courses. Your transcript's GPA and the UC-calculated GPA may differ, that's normal. What matters most is that your transcript clearly documents every course, grade, and credit so the admissions system has accurate data to work from.
Always include both weighted and unweighted GPA on your transcript, clearly labeled. Include your grading scale (e.g., A = 93–100 = 4.0) so reviewers know exactly how grades were assigned.
Common Mistakes to Avoid
These are the five mistakes California homeschool families make most often when building a transcript:
-
1Not filing a PSA or using a different school nameYour transcript should reflect the private school name on file with the CDE. If the name doesn't match, or no PSA was filed, it raises questions about your legal standing. File your PSA each fall and use the same school name consistently.
-
2Ignoring the a-g sequence until 11th gradeFamilies often discover the a-g requirements late and find gaps, a missing World Language credit or only two years of lab science. Plan the full four-year a-g sequence from 9th grade and track progress each semester.
-
3Vague course namesListing “Science” or “History” without specifics raises red flags with admissions reviewers. Use descriptive names (“Biology: Campbell & Reece, 11th ed.” or “AP US History”) and consider attaching a one-page course description document for selective colleges.
-
4Missing GPA or grading scaleLeaving off the GPA is one of the most common omissions. Include both weighted and unweighted GPA and your full grading scale (A = 93–100 = 4.0, etc.) directly on the transcript.
-
5Waiting until senior year to organize recordsReconstructing four years of curriculum details, grades, and hours from memory is stressful and error-prone. Start a running record the moment your student begins high school work, even if that's before 9th grade.
