Most high schools offer several ways to earn extra credits beyond the standard schedule, including adding classes to your day, taking summer courses, testing out of subjects, and enrolling in college courses that count toward both your diploma and a future degree. The right combination depends on what your school offers and what you’re trying to accomplish, whether that’s graduating early, boosting your GPA, or getting ahead on college requirements.
Add Classes to Your Schedule
The simplest way to earn more credits is to fill open periods in your school day. Many students have a study hall, late arrival, or early release period that could be swapped for an elective or required course. Talk to your guidance counselor about available slots.
Some schools also offer a “zero period,” which is a class that starts before the regular school day, often around 7:00 a.m. These are commonly used for electives like band, PE, or a world language, freeing up a period later in the day for another credit-bearing course. Not every school offers zero periods, so check with your counselor or registrar.
If your school runs on a block schedule (fewer classes per day but longer periods), you may be able to fit an additional course into an alternating block or request an overload. Schools that use traditional seven- or eight-period days sometimes allow an eighth class for students who can handle the workload.
Take Summer and Intersession Courses
Summer school is one of the most popular ways to pick up extra credits. Districts typically offer core courses like English, math, and health during a condensed four- to six-week session. You can use summer school to retake a class you struggled in, knock out a required course ahead of time, or add an elective that didn’t fit your regular schedule.
Some districts also run intersession or “winter mini” terms during longer breaks. These are shorter and usually cover half-credit courses like PE, health, or personal finance. Availability varies widely by district, so ask your counselor in the spring about summer options and watch for registration deadlines, which often fall in April or May.
Earn Credit by Examination
Many states let you earn high school credit by passing an exam in a subject, even if you never sat in the classroom. This is sometimes called credit by examination, or CBE. If you’ve already learned the material through self-study, tutoring, or life experience, testing out lets you add credits without spending a semester in the course.
The requirements vary by state and district. In some states, students who have not received prior instruction in a course earn credit by scoring 80% or higher on an approved exam. Students who have had some prior instruction in the subject may only need a 70%. Districts are generally required to offer these exams multiple times per year, and they cannot charge you a fee to take them.
Accepted exams often include those from the College Board’s Advanced Placement (AP) program and the College-Level Examination Program (CLEP). A score of three or higher on an AP exam, or 50 or higher on a CLEP exam, can earn you credit for the corresponding high school course. Some districts also accept exams developed by university-affiliated programs or by the district itself. Your counselor can tell you which exams your school recognizes and how to register.
A few states run formal credit acceleration programs that let you earn credit by passing a statewide end-of-course assessment without enrolling in the class. These typically apply to core subjects like Algebra 1, Geometry, Biology, and U.S. History.
Enroll in Dual Enrollment Courses
Dual enrollment lets you take college courses while still in high school, earning credit that counts toward both your diploma and a future college transcript. Programs are usually partnerships between your school district and a nearby community college or university. You take a real college course, taught to college-level standards, and receive college credit immediately upon passing.
Most dual enrollment programs require you to meet a minimum GPA (often 3.0, though some set the bar at 2.5) and may ask for a qualifying score on a placement test like the ACCUPLACER or SAT. Some programs are free to students, with the school district or state covering tuition. Others require you to pay part or all of the college tuition, so ask about costs before signing up.
Classes can be held at your high school, on the college campus, or online. The instructor may be a high school teacher approved by the college or a college faculty member. Either way, the coursework matches what any college student in that class would complete. You can typically take dual enrollment courses for both high school and college credit simultaneously, though some students choose to take them for only one or the other depending on their needs.
Dual enrollment is especially useful if you’ve already completed the advanced courses your high school offers in a particular subject. It can also save significant money on college tuition later, since you’ll arrive with credits already on your transcript.
Take Online Courses
Many districts accept credits from approved online programs, which is helpful when your school doesn’t offer a specific course or when scheduling conflicts block you from taking it in person. State virtual schools, district-run online programs, and accredited third-party providers all offer courses that can count toward your diploma.
Before enrolling in any online course, confirm with your counselor that your school will accept the credit. Some districts only recognize courses from specific providers or require pre-approval. Online courses range from free (through state virtual school programs) to several hundred dollars per course through private providers. Pacing varies too: some follow a set schedule, while others are self-paced, letting you finish faster if you’re motivated.
Use Independent Study or Directed Study
Some schools award credit for independent study, where you work one-on-one with a teacher on a subject not offered in the regular catalog. This could be an advanced research project, a creative portfolio, or deeper work in a subject you’ve already taken at the highest available level. You typically need a sponsoring teacher, a written learning plan, and approval from an administrator.
Independent study is less common than other options on this list, and not every school allows it. But if you have a strong interest in a niche subject like astronomy, creative writing, or computer science and your school doesn’t offer the course, it’s worth asking.
Look Into Work-Based Learning Credits
Some districts grant elective credit for structured work experience, internships, or apprenticeships. These programs go by different names: work-based learning, career practicum, or cooperative education. You typically need to work a minimum number of hours per week at an approved job site, keep a log of your activities, and complete assignments that connect the work to academic learning.
Your employer may need to fill out evaluation forms, and a school coordinator usually checks in periodically to verify you’re meeting the program’s requirements. These credits generally count as electives rather than core courses, but they free up space in your schedule and give you real-world experience.
Plan Ahead for Maximum Flexibility
The earlier you start planning, the more options you have. Mapping out all four years of high school with your counselor lets you spot where extra credits fit naturally. A student who takes PE over the summer before freshman year, for instance, opens up an entire period every semester for the next four years.
Keep a running list of credits earned and credits still needed. Your school’s graduation requirements set the floor, but many students benefit from going beyond it. Extra credits can let you explore interests, strengthen a college application, maintain eligibility for athletics or extracurriculars if your GPA dips, or simply give you a lighter senior-year schedule. Start the conversation with your counselor early, ideally before course registration each spring, so you don’t miss deadlines for summer school, dual enrollment, or exam sign-ups.
