The California State University (CSU) system uses your high school GPA and a standardized eligibility index to determine admissions qualification. Enter your A-G courses with grades and credits to calculate your CSU GPA, then switch to the Eligibility Index tab to see if you meet the CSU threshold.
Course Name — enter each a-g required course or elective.
Grade — select the letter grade earned in that course.
Credits — typically 3–4 per academic year course.
Switch to Eligibility Index and enter your SAT or ACT score to calculate your index.
CSU Eligibility Index Formula
The CSU Eligibility Index combines your GPA and test scores into a single number. California residents must reach a minimum index, while non-residents must meet higher standards.
SAT Eligibility Index = GPA × 800 + SAT Score
ACT Eligibility Index = GPA × 200 + ACT Composite
Minimum Index (CA Resident):
SAT-based: 2950 | ACT-based: 694
Minimum GPA alone: 3.0 (no test required at some campuses)
With GPA 2.0–2.99: must meet index threshold with test scores
Worked Example
A California resident has a 3.2 GPA and scored 1050 on the SAT:
SAT Index = 3.2 × 800 + 1050 = 2560 + 1050 = 3610
Minimum required: 2950 → Eligible
If the same student scored 21 on the ACT: ACT Index = 3.2 × 200 + 21 = 640 + 21 = 661
Minimum required: 694 → Not Eligible via ACT Would need 54 more index points: get a 27 ACT or improve GPA to 3.47+
CSU a-g Requirements
CSU requires completion of the a-g course sequence in high school for eligibility. These 15 required courses must be completed with a grade of C or better:
a) History/Social Science — 2 years
b) English — 4 years of college prep
c) Mathematics — 3 years (4 recommended)
d) Laboratory Science — 2 years (3 recommended)
e) Foreign Language — 2 years of the same language
f) Visual/Performing Arts — 1 year
g) College Prep Electives — 1 year
Frequently Asked Questions
California residents need a minimum GPA of 2.0 in a-g courses, though this is a floor for eligibility, not a guarantee of admission. Students with GPAs between 2.0 and 2.99 must also meet the eligibility index using test scores. Competitive CSU campuses like Cal Poly SLO typically admit students with GPAs well above 3.5.
CSU adopted a test-free admissions policy starting with Fall 2023 applicants. SAT and ACT scores are no longer used for admissions decisions. The eligibility index based on test scores still applies for students who apply under certain pathways, but most students are evaluated on GPA and a-g course completion alone. Check the specific campus for current requirements.
CSU calculates GPA using only your a-g courses from 10th and 11th grade (and any summer courses). Physical education, remedial classes, and non-academic electives are typically excluded. Your school's reported GPA may include all courses and all four years, making it different from what CSU recalculates from your transcript.
Yes — you can improve your GPA by earning better grades in remaining a-g courses, retaking courses where you earned a D or F (CSU uses the higher grade), or enrolling in community college courses that demonstrate academic ability. Since CSU is now largely test-free, focusing on GPA improvement in core academic courses is the most direct path to strengthening your application.
Cal Poly San Luis Obispo and Cal Poly Pomona are the most selective, often requiring GPAs above 3.5 and impacted majors like Engineering and Business. San Diego State, San Jose State, and Cal State Long Beach are also competitive. CSU Fullerton, CSU Northridge, and Sacramento State generally admit students closer to the minimum thresholds. Impacted programs at any campus may have higher GPA cutoffs than general admission.
