What Is the Difference Between Dual Enrollment and AP?
The main difference between the two is who awards the grade and the credit. An AP course follows a College Board framework, is taught in the high school, and leads to a standardized AP Exam in May that is scored from 1 to 5. A dual enrollment course, as the term is generally used, is a college course taken while the student is still in high school, and the college awards the grade.
| AP | Dual enrollment | |
|---|---|---|
| What it is | A high school course built on a College Board framework | A college course taken while still in high school |
| How it is assessed | The grade from the high school teacher, and a standardized AP Exam in May, scored from 1 to 5, for students who take it | The grade the college awards for the course |
| The record a college sees | The course and grade on the high school transcript, and the AP score where the student reports or sends it | The course and grade on a college transcript, and on the high school transcript where the school lists it |
| Who decides on college credit | Each college sets the score it accepts | Each college decides whether the course counts |
College Board describes an AP score of 3 as qualified, 4 as very well qualified, and 5 as extremely well qualified. AP Exams are standardized and scored on one scale, so an AP score can be compared across schools more easily than a single course grade.
What Do Princeton, Yale, Harvard, and MIT Say About Advanced Courses?
Princeton tells applicants to challenge themselves, whenever they can, with the most rigorous courses possible, such as honors, AP, and dual enrollment courses, and so names the two side by side. In the passages cited here, none of the four colleges states a preference between them.
Yale says it expects students to take advantage of AP courses only if their high school provides them, and that no student is disadvantaged for not using a resource that was not available to them. Harvard says a student who has taken college courses while still in high school, through dual enrollment or as supplementary coursework, is still considered a first-year applicant. The MIT Office of the First Year notes that many MIT students have done college-level study while in high school.
How a schedule is read in context is explained in our guide to course rigor in college admissions.
Does Dual Enrollment Credit Transfer to Selective Colleges?
At some of the most selective colleges it does not, and at some of them AP scores earn no credit either. Admission and credit are separate decisions, and the credit rules are specific to each college.
| College | AP scores | College courses taken in high school |
|---|---|---|
| Harvard | No degree credit. AP examinations can serve as placement tools and in some cases fulfill the language requirement. | Harvard does not accept credit for coursework completed before matriculation. |
| MIT | For the class entering in fall 2026, credit for a score of 5 on some AP exams, with no partial credit for lower scores. | Departments may grant credit if the subject is substantially equivalent to one taught at MIT and the grade meets MIT standards. An official transcript from the college is required, and no credit is granted for courses listed only on a high school transcript. |
| Princeton | No course credit. AP scores in some fields can fulfill prerequisites for a major, place a student in upper-level courses, or fulfill the language requirement. | College courses taken prior to matriculation cannot be accepted for Princeton credit. |
In our view, this is the point families most often miss: at Harvard and Princeton neither one counts toward the degree, and at MIT credit is limited and decided case by case, so the choice should be made for what the course teaches and what it shows, not for the credit.
How Does the University of California Count Dual Enrollment and AP?
The University of California is an example of a public university that counts both in its admission GPA. Its GPA rule adds an extra grade point for each semester of an honors-level course, up to 8 points between 10th and 11th grades. For California residents, its list of honors-level courses includes AP courses, IB Higher Level and designated Standard Level courses, UC-transferable college courses, and UC-certified honors courses.
The weight is not identical. The page gives one point for each semester of an honors-level course and says one college course equals one grade and one honors point. No more than 4 points can come from 10th grade, and a grade of D or F earns none. For applicants from outside California, the page says UC grants honors weight for AP or IB courses only. Rules elsewhere may differ, so a family with a state flagship in mind should read its admission and credit pages. For AP scores, the AP Credit Policy Search from College Board lists the policy at each college.
When Is Dual Enrollment the Better Choice?
At Oriel Admissions we advise AP as the core of an advanced schedule where the school offers it, and dual enrollment in three situations. The first is a subject beyond the AP courses, such as multivariable calculus or linear algebra for a student who has finished AP Calculus BC. The second is a school that offers few AP courses. The third is homeschooling, where a college grade gives an outside measure of the work; our guide to homeschool dual enrollment covers that case. We also advise choosing a college course with the same care as any other, because the grade becomes part of the record a college reads.
How Should a Family Decide Between Dual Enrollment and AP?
The decision turns on what the school offers and what the student plans to study.
| Situation | Our advice |
|---|---|
| The school offers the AP course in the subject | Take the AP course and the AP Exam |
| The student has finished the AP sequence in a subject | Add a college course at the next level |
| The school offers few or no AP courses | Use dual enrollment to add rigor in core subjects |
| The main goal is credit at a public university | Read the credit policy of that university for both before choosing |
| The main goal is credit at Harvard or Princeton | Neither earns credit toward the degree at these two colleges |
| The main goal is credit at MIT | A 5 on certain AP exams earns credit; college courses are reviewed department by department and need an official college transcript |
In our experience, the strongest schedules use both: AP courses through the highest level the school teaches, and one or two college courses in the subject the student cares most about. Related choices are covered in our guides to honors classes and the best AP courses for junior year.

Frequently Asked Questions About Dual Enrollment vs AP
An AP course is taught in high school and leads to a standardized AP Exam scored from 1 to 5. A dual enrollment course is a college course taken during high school, and the college awards the grade.
Princeton names honors, AP, and dual enrollment courses together as examples of the most rigorous courses and states no preference between them in that passage. At Oriel Admissions we advise AP as the core where the school offers it, with dual enrollment for subjects beyond the AP courses.
No. Harvard says it does not accept credit for coursework completed before matriculation. It also grants no degree credit for AP examinations, which it uses for placement.
Sometimes. MIT departments may grant transfer credit when a college course is substantially equivalent to an MIT subject and the grade meets MIT standards. An official transcript from the college is required.
For California residents, UC transferable college courses and AP courses both count as honors level courses in the admission GPA, though the weight is not identical. For applicants from outside California, the page says UC grants honors weight for AP or IB courses only.
Not at Harvard. It says a student who has taken college courses while still in high school is considered a first year applicant.
It depends on the course and the college. AP Exams are standardized and scored from 1 to 5, while a dual enrollment grade is set by the college that awards the credit.
We advise taking the AP course where the school offers it, and adding a college course for a subject beyond the AP sequence or where the school offers few AP courses.
