How Long Before Graduate School Should I Take the GRE: When to Test and Plan for a Retake

If you are asking “how long before graduate school should I take the GRE,” the short answer is: plan to take your GRE early enough to allow for study, one or more retakes if needed, official score reporting, and any program-specific requirements. For most applicants aiming to start a graduate program in the fall, a good rule of thumb is to take the GRE no later than early October of the year you apply. That timing gives you room for a retake and to receive official scores before typical application deadlines in December and January.

Why timing matters

When you schedule the GRE, you are balancing several practical factors:

• Preparation time. Most test takers need weeks or months of focused study to reach their target score.
• Retake options. You may want the opportunity to retake the GRE if your first score is below your target.
• Score reporting time. Official scores are released and available to programs after ETS processes them.
• Application deadlines. Programs have hard deadlines and some require scores as part of the initial application packet.
• Program policies. Some schools prefer or require recent scores, or they accept scores up to five years old but advise checking program-specific rules.

Key ETS policies you should know

• Score validity. GRE scores are valid for five years from the test date, but some programs ask for scores within a shorter window. Verify individual program policies.
• Score reporting timeline. Official GRE scores are typically available about 10 to 15 days after the test date for the computer-delivered General Test. Expect additional time for institutions to receive and process scores.
• Retake rules. You can take the GRE up to five times within any continuous 12-month period, with at least 21 days between attempts.
• ScoreSelect. ETS allows you to choose which GRE scores to send to schools from tests taken in the last five years. This can affect when you decide to retake the test.

Always confirm current policies on the ETS website before scheduling. Policies can change and some details vary by test format and region.

Recommended timing by application timeline

Below are practical recommendations depending on the application cycle you are following. These assume fall enrollment with typical December to February deadlines.

For fall admission (most common)

• Ideal earliest target. Take the GRE in the spring or early summer before application season if you want extra time to study and retake as needed.
• Latest safe date. Early October. This gives you time to retake in late October or November if necessary and still have official scores before many deadlines.
• If you miss early October. Check specific program deadlines. If a program has a late deadline in January, you may be able to take the GRE in November and still be safe. For rolling admissions or very early deadlines, plan earlier.

For spring admission or off-cycle programs

• Work backwards from the program deadline using the same logic: allow time for study, a retake, and official score reporting.
• If you plan to start in spring, a common approach is to schedule the GRE roughly six months before application deadlines.

For rolling admissions

• Apply early. Since rolling programs review applications as they arrive, aim to have your GRE done at least a month before you submit your application.
• Taking the GRE early can be an advantage because it lets you submit a more complete application sooner.

How much study time should you allow before your first GRE

Study time varies with your starting level, target score, availability, and test experience. These are general guidelines to help you plan.

• High baseline, small score gain needed. If your practice scores are near your target, plan 4 to 8 weeks of focused study with regular practice tests.
• Moderate baseline, medium score gain needed. Expect 2 to 3 months of study, including content review, strategy work, and practice tests.
• Low baseline, large score gain needed. Allow 3 to 6 months of steady study. Time to build skills matters more than cramming.

Quality beats quantity. Regular full-length practice tests are essential to monitor progress and build endurance. Many students benefit from a diagnostic test then a structured plan that focuses on weak areas.

Planning for a retake

Because many applicants retake the GRE, build retake time into your calendar rather than hoping you will not need it.

• Allow at least 6 to 8 weeks between your first test and the retake date to study intentionally on weak areas. The ETS minimum is 21 days, but that is usually not enough time to improve significantly.
• Schedule the retake so official scores arrive well before your earliest application deadline. If you take the first test in early October, a late October or early November retake often fits most schedules.
• Remember ScoreSelect. If your retake score is worse, you can choose to send only your higher score. Still, test timing should not be left to the last minute.

International students and test availability considerations

• Test center availability. Some locations have fewer test dates. Reserve slots early, especially during peak application months.
• Travel and logistics. Account for travel, visa-related documentation, and local holidays that may affect testing windows.
• Score reporting lag. If your institution requires hard copy translations or additional verification, start earlier. Most schools accept ETS electronic reports, but confirm if any extra steps are required for your country.

Practical timeline examples

These examples assume fall admission with common deadlines. Adapt dates for your specific deadlines and circumstances.

Checklist: scheduling and preparation timeline

• Set your application deadlines and note programs that have early or special deadlines.
• Run a diagnostic practice GRE to estimate study time needed.
• Plan and book your first GRE at least 2 to 3 months before application deadlines, earlier if you need more study time.
• Reserve at least 6 to 8 weeks between first test and your planned retake.
• Register early for test dates and test centers to secure a seat.
• Track official score release dates and when schools typically receive scores.
• Verify any program-specific rules on score age or reporting requirements.

Common scenarios and recommended actions

You are a busy working professional

Spread study over 3 to 4 months with weekly study blocks and one full-length practice test every 2 to 3 weeks. Schedule the GRE at least two months before deadlines so you can retake it if needed.

You are an undergraduate graduating this spring

Plan to take the GRE in the summer after junior year or early in your senior year. This reduces pressure during a busy final semester and leaves time for a retake.

You only need a basic GRE score for a few programs

Even if your target score is moderate, do one diagnostic test and allow 4 to 8 weeks of targeted study. Do not wait until the last minute since unexpected issues can arise.

Frequently asked questions

Can I use GRE scores from several years ago?

Yes. ETS retains GRE scores for five years. Many programs accept scores within that window. Some programs prefer more recent scores, so check each school’s policy before relying on an old result.

What if I miss a deadline for a program?

Contact the program admissions office. Some programs may accept late materials or allow you to submit GRE scores after applying, but you should not assume flexibility. If a program strictly enforces deadlines, take the GRE earlier next cycle.

Is there a benefit to taking the GRE earlier than necessary?

Yes. Taking the GRE early gives you time to retake and to spend application season focusing on essays, recommendations, and transcripts. Early scores also help with programs that review on a rolling basis.

How many times should I expect to retake the GRE?

Many applicants take the GRE once. Some take it twice. Plan for a possible second attempt but do not plan to retake more than necessary. Focused, deliberate study between attempts will yield better results than repeated testing without targeted review.

Final thoughts

Schedule your GRE so you have time for realistic study, at least one retake if needed, and official score reporting before any application deadlines. For most applicants aiming for fall admission, taking the test by early October is a safe target. If you prefer more buffer, take it earlier in the summer. Verify program-specific rules about score age and deadlines, reserve test seats early, and use diagnostic tests to set a study plan that matches your target score.
