How Long Are MCAT Scores Valid and When Do They Expire

I. How Long Are MCAT Scores Valid for Medical Schools?

The answer to the question “How Long are MCAT Scores Valid,” is a complex one. The score validity windows vary depending on which school you are applying to. Generally speaking, an MCAT score is valid for up to 2-3 years on average, although some may accept scores up to 4 years old. As a reference, for the 2026-2027 cycle of applications, most of the scores were from 2023-2024 onwards. Very competitive schools generally only accept scores that are two years old. Since each medical school has its own unique set of requirements, it is important to conduct research and verify the requirements for the medical schools you are applying to, so as to ensure your college accepts MCAT scores. Generally speaking, validity is assessed from the date that you will enter the program and not the date that you hit submit. It is also important to note that some schools also have a deadline on the latest date you can take the MCAT for a given application cycle. Always make sure to double check Medical School Admission Requirements (MSAR) for the most recent policies. Exam dates need to be coordinated with other requirements to understand whether most schools will accept MCAT scores.

II. Do MCAT Scores Ever Expire Officially?

AAMC test scores remain on the academic transcript indefinitely and schools accept scores from the AAMC no matter what. This means that schools have the ability to view all MCAT attempts, even those past their stated deadline. Whether a med school factors these scores is a different story.  Although AAMC is completely transparent with scores, schools view scores in a different light. Most medical schools want to see an MCAT that is reflective of your current abilities and will factor this into consideration. How long scores are valid is generally a sliding scale, and MCAT scores expire depending on which med schools you are applying to. This may work in your favor since if a past score was not amazing a newer most recent score will seem more reflective of your current abilities. Always make sure you email the admissions committees for clarifications on any policies that you are confused about. In general, scores that are valid in the eyes of the AAMC are not necessarily competitive in the eyes of a given medical school. Make sure most schools accept MCAT scores in your validity window.

III. How Long Is Your MCAT Score Valid If You Take a Gap Year?

Many programs generally count your gap years when they accept scores. As such it is important that you do the same. Make sure that when you are planning on taking the MCAT that you factor in the amount of time utilized in your gap year, as med schools will count this too. Calculate how long that will add on to the time between your MCAT and the date you matriculate to determine how long scores are valid. Read through the admissions guidelines to understand what an acceptable time is to write the MCAT and plan for this in advance. A study guide is linked below with the test dates for the 2025-2026  MCAT cycle to help you plan your gap years on the path to becoming a doctor.

IV. How Admissions Committees View Older MCAT Scores

How older MCAT scores are viewed by administration committees depends on the school you are applying to. Because the MCAT is a test of pre-medical knowledge base and foundational skills, it is generally a good idea to keep it up to date for application cycles. Most medical schools want to see if you can keep up with the changing base of knowledge in science and deal with the rigours of modern medicine. Older scores might place some doubt in the medical school’s mind if your foundational knowledge is still as strong as it used to be. As a general rule of thumb, make sure your MCAT score is only 1-2 years old as many med schools accept scores with this timeline. Make sure your school on your school list considers your scores valid as well! The answer to “how long are MCAT scores valid” depends heavily on what med schools you are applying to.

V. When Should You Retake the MCAT?

There are a few reasons as to when you should set a new MCAT date. The first is if your score is way too low to meet the threshold for a medical school application, or if you believe that your MCAT prep has improved to the point where you feel confident that you can easily get a higher score. It is also worth noting that there is a 7 retake limit set by AAMC, and if you truly do not need to retake, you should not. It is worth noting that to strengthen your MCAT score requires becoming prepared again, as well as being required to pay a fee to the AAMC. Generally, if your score is competitive and within the validity window of the schools list that you are aiming for a retake is unnecessary, and your time is better spent working on the other components of your medical school application. Many schools enjoy seeing a holistic application, and older MCAT scores are not the biggest deal sometimes. You can learn more about when to retake the MCAT here, and whether or not your school accepts MCAT scores, if you are wondering if it will improve your application file. Try not to rush this decision, as it can involve up to two years of your life, and understanding what you stand to gain while you wait for medical school is important. It is also worth considering how interested you are and how much focus you will have to retake the MCAT. Ensure to survey all of your options!

VI. How to Plan Your MCAT Timeline Around Application Cycles

The best time to begin MCAT prep if your MCAT score expires is the spring or summer before the application cycle begins. Applying earlier in the application cycle is always a better idea, and your MCAT scheduling should reflect this so your older MCAT score can be replaced. Having your test results ready for submission ahead of time will take a load off your already massive to-do list of things to do for the medical school application cycle. Attempt to work backwards from your class matriculation date to choose a test date. For example if you want to begin medical school in 2029, it would be ideal to have a strong MCAT prep practice going into January 2028 for a test day in mid 2028. Plan out the timeline carefully to avoid any last-minute stress and anxiety and to avoid older scores.

VII. How Long Are MCAT Scores Valid Compared to Other Requirements?

Your GPA, clinical experience and prerequisite courses generally never expire, however the MCAT date is unique in that it does have an expiry date in the eyes of many medical schools. Thus, MCAT scores serve as a snapshot of your current knowledge of the foundational premedical sciences for a certain amount of time. Having a solid and recent MCAT exam score combined with good shadowing and clinical experience will give your application the best chance. Understand that applications are assessed holistically, so try not to spend too much of your time on any one aspect. Just ensure your medical school application is up to date and that most schools will accept your MCAT scores.

VIII. Common Mistakes When Calculating MCAT Score Validity

The biggest mistake that students tend to make when calculating MCAT score validity is assuming that most medical schools blanket three-year rule for every single school. As such it is always important to do research into every single school you are applying to so that you can confirm requirements to confirm if scores are valid. Ensure that you calculate MCAT score validity based on the expected matriculation date to test day time and not the application date, as this is another mistake that some students can make. In general, prophylactic research into the medical schools that you are applying to is your best friend when dealing with these deadlines. The answer to the question “How Long are MCAT Scores Valid” is one that has nuance and requires further research. Acceptable scores are an important part of a medical school application. Make sure you do research into the time ranges for acceptable scores.
