Georgia keeps its diploma rules relatively clean, but two things surprise families who move in from other states. The first is how much math and science the state demands. The second is that the diploma and the state's famous scholarships are not the same finish line, and treating them as one is the mistake that costs money later.
The short version: 23 units, with four full years each of math and science, no exit exam to pass, and the HOPE and Zell Miller scholarships sitting on a separate, higher track. Here is each piece with the real numbers.
The 23 units, course by course
The state minimum in Georgia is 23 units, and the breakdown leans academic:
- English or language arts: 4 units
- Mathematics: 4 units
- Science: 4 units
- Social studies: 3 units
- Health and physical education: 1 unit, split as a half unit each
- Career tech, world language, or fine arts: 3 units, drawn from any of the three areas
- Electives: 4 units
The number to notice is the science count. Georgia requires four units of science, and four of math, where a lot of states stop at three. That extra year on each side is real, and it shapes a Georgia student's schedule more than families expect, leaving less elective room than a three-and-three state would. The three-unit block that mixes career tech, world language, and fine arts is the flexible part, and it is where a student's interests, or a college's expectations, tend to steer the choices.
The Milestones exams, and no exit exam
Georgia students take Georgia Milestones end-of-course exams in four subjects: American Literature and Composition, Algebra, U.S. history, and Biology. Here is the key point, because it is easy to get wrong. Those exams are not a graduation gate. The score counts as part of the final grade in that course, and the state has sharply cut how much it weighs in recent years, but no single Milestones test blocks a diploma the way an old-style exit exam would.
That is a deliberate change. Georgia used to require students to pass a separate graduation test, and it scrapped that standalone exam years ago. So a Georgia diploma turns on completing the 23 units and passing the required courses, not on clearing a make-or-break test score. If you are arriving from a state that still has an exit-exam requirement, this is one less thing to track, though the Milestones still matter enough as part of the course grade that they are not something to blow off.
HOPE and Zell Miller sit on top of the diploma
The HOPE and Zell Miller scholarships, the state lottery-funded awards that make in-state college dramatically cheaper, are not tied to simply graduating. They have their own standards, and those standards are higher than the diploma.
HOPE requires a student to graduate with at least a 3.0 grade point average calculated the state's way, and to complete a set of rigorous courses, things like advanced math and science, Advanced Placement or dual-enrollment classes, and upper-level world language. Zell Miller, the fuller award, wants roughly a 3.7 and adds minimum SAT or ACT scores on top. The consequence is the same one families hit with California's college-prep track or Florida's Bright Futures: a student can satisfy every graduation requirement, walk at commencement, and still miss the scholarship because they skipped the rigor courses or fell under the grade point cutoff. In a state where HOPE can be the difference between affordable and not, that is an expensive miss. If a Georgia public college is realistically in the picture, plan to the HOPE and Zell Miller standard from ninth grade.
What to actually do with this
Three steps. First, pull your district's course catalog, because districts build on the 23-unit state floor and some require more, and the catalog tells you exactly which courses satisfy the science, math, and flexible blocks. Second, if college is the goal, get the current HOPE and Zell Miller rigor-course and grade requirements and plan the four years around them, not around the diploma minimum. Third, do not ignore the Milestones just because they no longer gate graduation, since they still count in the course grade that feeds the grade point average the scholarships care about. For families comparing schools, our rankings of the top rated high schools in Georgia and the best schools in Gwinnett County put the data behind the choices, and the graduation requirements by state guide shows how Georgia's heavier math and science load compares nationally.
Data note: unit and exam figures reflect Georgia Department of Education Rule 160-4-2-.48 and Georgia Milestones policy as of August 2026. HOPE and Zell Miller criteria are set separately and change periodically, so confirm current requirements with your district or the state scholarship agency.
