Both AP and dual enrollment can earn college credit in high school, but they differ on cost, transfer rules and scheduling. Here is how to compare them for your online student.
Quick takeaways
- AP credit comes only from a qualifying exam score of 3, 4 or 5, while dual enrollment credit is earned by passing an actual college course.
- More than 95 percent of colleges award credit for qualifying AP scores in popular courses, but each college sets its own minimum scores.
- Dual enrollment grades appear on both high school and college transcripts and affect cumulative GPAs at both, so a rough semester follows your teen.
- Some state dual enrollment programs are tuition-free, while families in other states pay standard college tuition and fees; rules vary by state.
- AP courses and exams are standardized, while dual enrollment quality and transfer policies vary widely from state to state.
If your online high schooler wants a head start on college credit, two paths usually come up: Advanced Placement (AP) courses and dual enrollment. Both are popular, and both can save families time and money later, but they work in very different ways. The differences show up in cost, how credit is earned, whether credit transfers and how each option fits an online schedule. Here is a side-by-side comparison to help you match the choice to your teen’s goals, schedule and budget.
The Basic Difference in a Nutshell
AP courses are college-level classes offered within the high school curriculum. College faculty review and approve AP course material so that students are asked to do college-level work no matter where they take the class. There are 42 AP courses across multiple subject areas, and each school decides which of them it offers. College credit comes only from the AP Exam, given each May and scored from 1 to 5. Taking the exam and earning a qualifying score is the only way a student turns an AP course into college credit or advanced placement.
Dual enrollment means enrolling directly in college courses while still in high school, usually through a community college or university. Classes might run online, on a college campus, or at the high school, taught by college instructors or by high school teachers who meet college qualification standards. When the student passes the course, college credit is earned. There is no separate exit exam. Nearly 2.8 million students took college courses in the 2023-24 school year, and college classes now reach students at about nine in ten public high schools nationwide. For comparison, nearly 3 million students took AP Exams in 2024.
AP and Dual Enrollment at a Glance
| Question | AP | Dual enrollment |
|---|---|---|
| What is it? | A college-level high school course ending in a standardized exam | An actual college course taken through a college or university |
| How credit is earned | A qualifying AP Exam score of 3, 4 or 5 | Passing the college course itself |
| Typical cost | Course usually free or at a reduced rate through the school; an exam fee applies per exam | Some state programs are tuition-free; others charge standard college tuition and fees |
| Effect on grades | Exam scores do not affect high school GPA | The grade appears on both high school and college transcripts and affects cumulative GPAs |
| Quality check | Course frameworks reviewed by college faculty, plus a standardized exam | No single national standard; state quality policies vary widely |
Neither option wins across the board. The right fit depends on how your teen learns, where they plan to attend college and what your state funds.
Cost Compared: Exam Fees vs. Course Tuition
The cost structures differ from the start. AP courses are typically free or offered at reduced rates through the high school, with the main out-of-pocket cost being the fee for each AP Exam. Fee assistance exists: state subsidies contributed to a 56 percent rise in AP Exam participation among low-income students from 2015 to 2025. Other AP costs are low. Every year a teen takes an AP Exam, they are entitled to send one free score report to whichever college, university or scholarship program they choose, and the AP Classroom platform offers free practice materials and video lessons covering every topic and skill the exam tests.
Dual enrollment pricing varies much more by state and college. Some programs cost families nothing. North Carolina’s Career and College Promise, for example, offers tuition-free college course credits to students in grades 9 through 12. Elsewhere, families pay the college’s standard rates: at Massachusetts Bay Community College, traditional dual enrollment students are charged standard tuition and fees, paid in advance of each semester. Ask the counselor what your state’s program covers and whether your online school picks up any portion, and get the full list of charges, including lab fees and textbooks.
Helpful tip
Before enrolling in anything, ask for the total cost in writing: exam fees, tuition, lab and course fees, and materials. What a state program advertises and what a specific college bills are not always the same thing.
How Credits Transfer and Where They Count
AP credit is the more standardized of the two. The majority of colleges give credit, placement or a combination of the two for qualifying scores, and in the most popular AP courses, more than 95 percent of colleges and universities accept qualifying scores for credit. Each college still sets its own rules: a 3 might earn credit at one school while another requires a 4 or 5, and some colleges do not accept AP credits at all. The College Board’s AP Credit Policy Search tool lets you look up specific colleges’ policies before your teen commits to a course. Research cited by College Board also found that 2 out of 3 AP students earn some college credit in high school.
Dual enrollment credit is earned automatically by passing the course, but what happens to it afterward depends on the receiving college. Transfer policies vary widely, and the process can get confusing when a high school works with multiple college partners. Quality oversight also varies. Figures from the National Alliance of Concurrent Enrollment Partnerships show that 18 states have policies setting quality expectations for their dual enrollment programs as a whole, 22 address only some pieces of program quality, and 10 states plus the District of Columbia have put no statewide quality policy in place. Because there is no standardized measure of what a dual enrollment course covers, admission officers can find it harder to judge its difficulty than an AP course. Some states have responded: Virginia passed legislation in 2018 to improve dual enrollment quality and increase the likelihood that its public four-year institutions accept the credits, and teachers of dual enrollment there must meet the same qualification requirements as community college faculty, including 18 graduate credits in the subject taught.
Rigor, Grading and How Each Looks on a Transcript
AP classes aim for college-level rigor but remain part of the high school curriculum, taught by high school teachers trained for the courses. The grade in the course counts toward high school GPA; the exam score does not. Colleges that receive score reports see the exam results separately.
Dual enrollment courses are genuine college classes, often taught by college professors, so the workload and expectations match what enrolled college students face. The grade follows your teen onto a college transcript and affects their cumulative college GPA. That permanence cuts both ways: a strong semester gives your teen a verified college record and a head start on requirements, while a weak grade becomes part of that same record. Dual enrollment generally suits students who are ready for college coursework but less confident in standardized tests; AP tends to reward students who test well.
Workload, Scheduling and Eligibility
For online students, scheduling is often the deciding factor. AP courses fit inside the regular high school schedule and end with the May exam, so an online school’s calendar and the exam date need to line up. Dual enrollment runs on the college’s calendar, with its own start dates, deadlines and login systems, which can overlap or conflict with high school coursework. Either way, college-level reading and assignments demand steady study habits. Our tips for staying focused in online classes apply to both options, and our guide to taking notes from video lessons helps with the lecture-heavy formats common in college courses.
Eligibility also differs. AP courses are signed up for through the high school, and availability is limited to what the school offers; some schools, districts or states require students who take an AP course to sit for the exam. Dual enrollment is arranged through the college, usually with help from a school counselor, and requirements vary. One example: Massachusetts Bay Community College requires traditional dual enrollment students to be in grades 9 through 12, hold at least a 2.5 cumulative high school GPA on a 4-point scale, and place into college-level math and English through placement testing or a waiver, with immunization requirements for students taking 9 or more credits in a semester on campus. Homeschooled students may qualify with permission from a local school or district. Check with your state agency and prospective colleges for the rules where you live.
Questions to Ask Your School and Target Colleges
Bring these questions to your teen’s counselor and to the admissions or registrar offices at colleges your teen is considering. If you are still comparing online schools themselves, our guide to choosing an online school includes questions worth asking before you enroll.
- Which of the 42 AP courses does our school offer, and is taking the exam required?
- What exam fees apply, and is fee assistance available for our family?
- Which college partners with our school for dual enrollment, and who pays tuition and fees?
- Does that dual enrollment program meet a statewide quality standard or NACEP accreditation?
- Will the colleges my teen is considering accept these credits, and with what minimum scores or grades?
- How will AP scores or dual enrollment grades appear on the transcript?
- How will the workload fit alongside my teen’s current online courses?

Choosing Based on Your Teen’s Goals
Dual enrollment tends to fit self-driven students who want an authentic college experience and can handle the maturity and time management demands of a college course. Because credit is earned by passing, it appeals to teens who are ready for college work but uneasy about standardized exams. It can make particular sense for a student with a clear direction, since courses can count toward both the high school diploma and a college degree, and some state programs offer defined transfer pathways.
AP tends to fit students who want a college-level challenge within a familiar high school structure, especially those who perform well on exams. The standardized exam gives colleges across the country a shared basis for judging the work, which is useful if your teen has not settled on a specific school. A solid AP performance can also help applications stand out to colleges and scholarship programs.
Budget matters too, but check what your state actually funds rather than assuming either option is cheap or free. Rules, subsidies and partnerships change from state to state, and the counselors and colleges involved are the best source for current details. Neither choice is permanent, either; many students mix both over four years of high school.
A concrete first step: ask your teen’s school for its list of AP course offerings and the names of its dual enrollment partner colleges, then use the AP Credit Policy Search tool and each college’s transfer pages to see whether the credits your teen is weighing would actually count where they want to go.
Parents and students ask
Can a course be both dual enrollment and AP?
Only if the teacher and school submit the AP Course Audit form and syllabus for review and the course is authorized. The AP designation can only be used with official AP course titles.
Do AP exam scores affect my teen’s high school GPA?
No. AP exam scores do not impact high school GPA. Dual enrollment grades, in contrast, appear on both the high school and the college transcript and affect cumulative GPAs.
Can homeschooled students take dual enrollment courses?
Often, yes, but rules vary. Some colleges allow homeschooled students with permission from a local school or district, along with GPA, placement testing and application requirements.
Are dual enrollment credits guaranteed to transfer to a four-year college?
No. Receiving colleges set their own transfer policies, and state quality rules vary, so check with each college your teen may attend before enrolling in a course.
