Whether you dream of becoming a doctor, earning your Master of Business Administration (MBA) degree, or enrolling in another advanced career graduate program, applying to study in the United States requires scores from one of the main exams for graduate school: DAT, GMAT, GRE, LSAT, MCAT, or the OAT. A grad school test is typically administered via computer at an official testing center and requires a few months of studying.

Read on to learn more about these grad school standardized tests so you can start preparing for your studies!

What Grad School Tests Do You Need To Take?

Choosing your particular postgraduate program is the first step in figuring out which one of the grad school standardized tests will be required. A firsthand source can provide the most accurate information, so consider speaking with a university advisor or enrollment officer about their requirements for admission. You can also speak to an advisor through Shorelight’s international student services.

Different programs and schools may require specific grad school standardized test scores. For example, if you want to go to law school, your top-choice university may have a minimum LSAT score in order to be admitted. Alternatively, some programs may waive test score requirements for candidates who meet certain conditions (e.g., have met a minimum grade point average as an undergraduate student, or have several years of professional experience in a related field). 

As international students, you may need to take additional English tests such as TOEFL or IELTS to prove your English proficiency. As these requirements can vary, it is important to clearly understand a postgraduate program’s requirements before applying for grad school standardized tests. 

How to Prepare for Standardized Tests 

Knowing what to expect before you begin studying for your grad school standardized tests can help you prepare. Learning more about the exact requirements early gives you a good head start to preparing more effectively, so you can work toward achieving the required scores for your chosen university. 

When preparing for your standardized test, taking enough time to study can make a significant difference for your final score. Usually, most standardized testing institutions recommend a 12-week preparation period, but this can be longer or shorter depending on your familiarity and confidence with the testing material. 

Gather the recommended and available resources for your grad school standardized tests and use them for your study prep. Most testing institutions offer exam resources and mock exams on their websites; test prep companies, such as Kaplan and Khan Academy, may offer useful materials as well.

What Is the DAT?

The Dental Admission Test (DAT) is an entrance test that is required for admission to dental school in the US. It measures the test taker’s understanding of the survey of the natural sciences, perceptual ability, reading comprehension, and quantitative reasoning in relation to the study of dentistry.

Since dentistry is considered one of the best jobs in the US, graduate admissions to dental school are competitive. Like some tests needed to enter grad school, you must apply to take the test before registering.

The DAT takes five hours and 15 minutes, including an optional break, tutorial, and survey. The exam consists of the following sections:

  • Survey of the Natural Sciences

  • Perceptual Ability Test (PAT)

  • Reading Comprehension 

  • Quantitative Reasoning

DAT test-takers will receive six scaled scores in the range of 1-30. Scores include four scores based on individual test section results, an Academic Average, and a total science score. Once you finish the DAT exam, you will be given an unofficial score report at the testing center. Official results will be reported electronically within three to four weeks of the testing date to the selected schools you mentioned in your application, and will be posted to your My Account page at ada.org/dentpin

Non-refundable exam fees for the DAT are $525 each time you take it. DAT scores are valid for two years and you can take the exam three times before requiring special permission to take it again. 

November 2023 update

While Prometric, the global testing services provider, had initially closed its testing centers due to the COVID-19 pandemic, they have resumed testing again in more than 97% of their global testing centers. Reopened centers do not require masks to be worn in test centers, but will encourage students to follow health measures regardless of mandate or vaccination status. 

For more information, please visit the Prometric COVID-19 FAQ website.


Many admission tests feature questions within the exam that do not count toward your score. However, you are not informed on which questions are experimental. With many tests, there is no penalty for guessing, which means you should attempt to answer each question. 

What Is the GMAT?

The Graduate Management Admission Test (GMAT) is a graduate admissions entrance exam designed for students who want to go to graduate school for an MBA, master of accountancy, or master of finance. Some programs may accept GRE scores instead, depending on the applicant’s other credentials. 

This grad school admission test covers analytical writing and quantitative reasoning skills, as well as integrated and verbal reasoning skills. The ability to analyze and evaluate written material in English is important to note for English as a Second Language (ESL) students.

The GMAT consists of four sections and takes approximately three hours and 30 minutes, including the optional breaks, to complete.

  1. Analytical Writing Assessment

  2. Integrated Reasoning

  3. Quantitative Reasoning

  4. Verbal Reasoning

GMAT scores are given in increments of 10 points, within a range of 200 to 800. The quantitative and verbal sections have the same score range of 6-51 while the analytical writing section has a score range of 0.0 to 6.0, and the integrated reasoning section has a score range of 1-8. 

You can retake the exam only five times a year (even if scores are canceled) with a minimum gap of 16 days between each attempt, and up to eight years in your lifetime.  

Non-refundable exam fees for the GMAT range between $250-$300 each time you take it, depending on your location, and if you take your exam at a test center or online. Your recorded scores are valid for five years.

November 2023 update

Due to the COVID-19 pandemic, the Graduate Management Admission Council (GMAC) continues to maintain the online version of the standard GMAT, open to all candidates globally excluding Mainland China, Cuba, Iran, North Korea, and Sudan (because of regulatory and local data privacy rules). The GMAT online registration fee is $275 in most parts of the world, but a few countries have local prices.


Typically, calculators, timers, mobile phones, or other electronic devices are not allowed in official testing rooms. 

What Is the GRE?

The Graduate Record Examinations (GRE) is a grad school standardized test required for admission to various graduate programs at universities and colleges in the US, often those focused on the liberal arts. The GRE evaluates verbal and quantitative reasoning, as well as analytical writing and critical thinking skills, so English comprehension is important for international students preparing to take the GRE.

The GRE is the most common general admissions exam, and it offers additional specialized standardized tests that measure knowledge for degree programs like mathematics, physics, or psychology.

The GRE General Test takes one hour and 58 minutes to complete and consists of three sections. 

  1. Verbal Reasoning

  2. Quantitative Reasoning 

  3. Analytical Writing 

Candidates receive separate scores for each section. Verbal and Quantitative Reasoning are scored on a scale of 130-170 in one-point increments, while Analytical Writing is scored on a scale of zero to six in half-point increments. 

While there are no set pass or fail scores for the GRE, if you are unhappy with your scores, you can retake the grad school exam every 21 days, up to five times a year. 

The GRE General Test fee for most countries is $220 in all countries except for China, where the fee is $231.30, and India, where the fee is $270 (₹22,550), each time you take it.

November 2023 update 

The ETS, in response to the COVID-19 pandemic, has introduced the GRE General Test at home — identical in content, format, and on-screen experience to the standard GRE. It can be taken everywhere the computerized GRE is available. If you are taking the exam in China, you must visit the official GRE site for China for specific information, policies, and procedures related to the test and registration.

For more information, please visit the GRE General Test website.

What Is the LSAT?

If you plan to pursue a law career in the US, attending law school is the typical pathway. First, the Law School Admission Test (LSAT) is required to apply to most law school graduate programs in the US. This grad school test measures reading comprehension, logical reasoning, analytical reasoning, and writing. Law schools in the US are competitive, so a good LSAT score is important in the admissions process.

Test-takers must analyze and evaluate written material, which is a consideration for international students who do not speak English as their first language. 

The LSAT takes approximately three hours to complete and consists of five sections that test a candidate’s logical reasoning, reading comprehension, analytical reasoning, and writing skills.

Starting August 2024, the LSAT will undergo an update to its structure. It will continue to have five sections, but will only cover logical reasoning, reading comprehension, and writing. 

LSAT’s scaled scores range from 120 to 180 with an average score of approximately 152. Since law school is very competitive in the US, a score above average will improve your chances of admission. Scores are typically received two to four weeks after the grad school exam.

Exam fees for LSAT are $222 each time you take it. The LSAT can be taken up to three times a year, up to five times in five years (within the current reporting period), and up to seven times in your lifetime.

November 2023 update 

Since many LSAT takers preferred the availability of the online test, the LSAC continues to provide an online version of the LSAT that costs the same as the standard LSAT. For more specifics, visit the LSAT website

What Is the MCAT?

The Medical College Admission Test (MCAT) is required for admission to most medical graduate programs in the US. While knowledge of biology, physics, psychology, sociology, general and organic chemistry, inorganic chemistry, and biochemistry is crucial, the grad school test also measures critical analysis and reasoning skills necessary to study to become a medical doctor.

Medical school in the United States is competitive, so MCAT scores factor heavily into admission decisions. Unlike most grad school standardized tests, which take around four or five hours, the MCAT takes seven hours and 30 minutes, including test-day certification, an optional tutorial, optional breaks, a void question, and a post-exam survey.

The MCAT consists of four multiple-choice sections.

  1. Chemical and Physical Foundations of Biological Systems

  2. Biological and Biochemical Foundations of Living Systems

  3. Psychological, Social, and Biological Foundations of Behavior 

  4. Critical Analysis and Reasoning Skills (CARS)

Each section is scored on a scale of 118 to 132. The total MCAT score is a sum of the scale scores from the four sections and the test can be taken three times per testing year, four times over two consecutive testing years, and up to seven times in your lifetime. 

The standard registration fee for the MCAT begins at $335. Those testing outside the US, Canada, or US territories will be charged a $120 international fee in addition to the initial registration fee. Rescheduling and cancellation fees range between $50-$200, depending on the date of registration.

Students with financial limitations can register for the fee assistance program by paying $140. The benefits of the fee assistance program include discounted fees, complimentary access to the MSAR online database, free MCAT Official prep products, and more. International students are eligible for the Fee Assistance Program if they have a permanent US address prior to completing their application.

November 2023 update

The American Medical Colleges (AAMC) offer 30 MCAT test dates for 2024. There are four test dates in January, and then a break before testing resumes in early March. Starting March 9, tests are administered frequently until mid-September, with the final test date being September 14, 2024, and tests are held once per day starting at 8 a.m. Scores are released roughly one month after the test date. Visit the MCAT website to see the availability of test dates for your location.

What Is the OAT?

To become an optometrist, or eye doctor, the Optometry Admission Test (OAT) is required for admission to Doctor of Optometry (OD) programs at the US’s 23 schools of optometry. 

The grad school admission test measures aptitude in the survey of natural sciences, reading comprehension, physics, and quantitative reasoning. Like the DAT, you must apply to take this exam.

The OAT takes five hours and five minutes to complete, including an optional 15-minute tutorial, a 30-minute break, and a 15-minute optional post-test survey. The exam consists of four multiple-choice sections:

  1. Survey of the Natural Sciences

  2. Reading Comprehension

  3. Physics

  4. Quantitative Reasoning

OAT is scored in increments of 10 points within a range of 200 to 400. The final score is obtained by scaling the raw scores from the individual sections. 

Non-refundable exam fees for the OAT are $515 each time you take it and scores are valid for two years. You can take the exam three times, with a minimum of 60 days between each attempt, before requiring special permission to retake it. Only four attempts are permitted during 12 months and after the fifth attempt, test-takers can only retake the once per 12-month period.

November 2023 update 

While Prometric, the global testing services provider, initially closed its testing centers due to the pandemic, they have resumed testing again in more than 97% of their global testing centers. Reopened centers are closely monitored; however, they will not require masks to be worn in test centers, but will encourage students to follow health measures regardless of mandate or vaccination status.
