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.

Annual PSA reminder: The PSA filing window opens October 1 and closes October 15 each year. Missing the window doesn't invalidate your homeschool, you can file late, but filing on time keeps your records clean and your private school status unambiguous on any transcript you produce.

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)
Homeschool note for UC/CSU: UC and CSU do not maintain a list of approved homeschool courses the way they do for public schools. Your transcript, a course description document, and, for UC, self-reported activities and test scores together form your student's full application picture. Strong course names with clear descriptions are essential.

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 credits4.0 credits
Mathematics (c)3.0 credits4.0 credits
Lab Science (d)2.0 credits3.0 credits
History / Social Science (a)2.0 credits3.0 credits
World Language (e)2.0 credits3.0 credits
Visual / Performing Arts (f)1.0 credit1.0–2.0 credits
College-Prep Elective (g)1.0 credit1.0 credit

DiplomaPath tip: Since California sets no fixed requirements, DiplomaPath lets you set custom credit targets for each subject. Set your targets to match the a-g sequence, or go beyond it, and the Requirements tracker shows your student's progress in real time.

Required Elements of a Complete California Transcript

Use this checklist when building your transcript. Every item below should appear on the final document:

  • Student information
    Full legal name, date of birth, address
  • Private school name
    The name you filed on your PSA (e.g., “Golden State Academy” or “The Martinez Home School”)
  • Courses organized by year
    Group by grade (9th, 10th, 11th, 12th) or by academic year, note which a-g subject each course satisfies
  • Grades and grade points
    Letter grade and numeric grade point value; include your grading scale
  • Credits per course
    Standard full-year course = 1.0 credit; semester course = 0.5 credit (Carnegie Unit standard)
  • Cumulative GPA, weighted and unweighted
    Include the scale used (e.g., A = 4.0; Honors +0.5; AP/PSEO +1.0)
  • Total credits earned
  • Expected graduation date
  • Parent signature and title
    Sign 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:

  • 1
    Not filing a PSA or using a different school name
    Your 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.
  • 2
    Ignoring the a-g sequence until 11th grade
    Families 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.
  • 3
    Vague course names
    Listing “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.
  • 4
    Missing GPA or grading scale
    Leaving 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.
  • 5
    Waiting until senior year to organize records
    Reconstructing 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.
