Your Guide to Tackling the ISAT

The International Student Admissions Test (ISAT) is a computer-based admissions test developed by the Australian Council for Educational Research (ACER). It assesses critical and quantitative reasoning skills and is used as part of the admissions process for selected university courses, including medicine and other health-related programmes.

For students in Singapore who are considering studying medicine in Australia, understanding the ISAT test format, registration process, test dates and university requirements can help you plan your application more effectively.

Whether you are beginning to explore medical school options or preparing for an upcoming admissions cycle, this guide covers the key ISAT information you need to know.

What Is the ISAT?

The ISAT is a three-hour, computer-based multiple-choice test designed to assess reasoning skills rather than knowledge of specific school subjects.

The test contains 100 questions, presented in units consisting of stimulus material followed by questions. Each question has four or five answer options, with one correct answer. There is no negative marking for incorrect answers.

The ISAT focuses on two main areas:

  • Critical Reasoning: Understanding and analysing information, evaluating arguments, drawing conclusions and applying ideas. Questions use material from areas such as the humanities and social sciences.
  • Quantitative Reasoning: Analysing and applying information, solving problems, drawing conclusions and making decisions. Questions use material from mathematics and the sciences.

The ISAT is not designed to test detailed knowledge of biology, chemistry or other specific school subjects. Instead, it focuses on how effectively you can interpret information, reason through problems and reach appropriate conclusions.

Do Singapore Students Need to Take the ISAT?

ISAT requirements depend on the university, degree programme and applicant category. Not every Australian university requires the ISAT, so you should always check the latest admission requirements for each course you are considering.

Applying to Monash University

Monash University requires international applicants to complete the ISAT for its Direct Entry Bachelor of Medical Science and Doctor of Medicine (MD) programme.

For the 2027 entry cycle, Monash states that applicants must achieve:

  • An overall ISAT score of at least 170.
  • A minimum score of 165 in both Critical Reasoning and Quantitative Reasoning.

ISAT results are used for interview selection and contribute to the overall ranking for entry. Meeting the minimum score does not guarantee an interview or an offer of admission.

Monash also states that applicants should complete the ISAT before the relevant course application closing date. Requirements and deadlines may differ depending on the applicant’s educational background, so review the official course information before planning your test date.

Applying to UNSW Medicine

The University of New South Wales (UNSW) accepts either the UCAT ANZ or ISAT for eligible international applicants applying to its medicine programme.

For international applicants, UNSW lists an ISAT minimum score of 165 as one of its selection requirements. Applicants must also meet the relevant academic requirements and complete an interview if selected.

The exact requirements may vary according to your educational background and application pathway. Check the latest UNSW admissions information before registering for the test.

Other Universities

Some other universities may accept or require the ISAT for particular courses or applicant categories. The official ISAT website provides information about participating universities, but requirements can vary between programmes.

Before booking your test, consider the following:

  • Which universities accept or require the ISAT?
  • Does your chosen degree require a minimum score?
  • Is there a minimum score for each section?
  • What is the application deadline?
  • Does the university require you to nominate it when registering for the ISAT?

Always confirm the requirements directly with your target university.

ISAT Test Format and Scoring

The ISAT is a three-hour assessment with 100 multiple-choice questions. It covers two areas: Critical Reasoning and Quantitative Reasoning.

Test component

What it assesses

Critical Reasoning

Comprehending, analysing and evaluating information and arguments

Quantitative Reasoning

Analysing information, solving problems and making decisions

Unlike some other admissions tests, the ISAT does not focus on specific subject knowledge. Instead, candidates are expected to apply reasoning skills to unfamiliar information and problems.

 

How to Register for the ISAT

Registering for the ISAT involves several steps through ACER and ProctorU.

Step 1: Review the Registration Requirements

Before registering, read the official ISAT registration information and check whether the test is required for your target university and programme.

You should also review the technical and identification requirements for remote-proctored testing.

Step 2: Create an ACER Account

Create an account through the official ACER registration portal. You will use this account to manage your ISAT registration and access relevant information.

Step 3: Register for the ISAT

Complete the ISAT registration process through your ACER account. During registration, you may need to nominate the university or universities that can access your results.

Check your information carefully before submitting the registration.

Step 4: Create a ProctorU Account

After registering through ACER, you will need to register for a ProctorU account. The ISAT Office will then provide an invitation to book your test session.

Step 5: Book Your Test Session

Use the ProctorU booking process to select your test session. Make sure you understand the test-day requirements and complete any necessary technical checks before your appointment.

How Much Does the ISAT Cost?

For the 2026 test cycle, the ISAT registration fee is AUD 435. Payment is made to ACER during registration.

Additional costs may apply depending on your circumstances. For example, a deferral request incurs a AUD 72 deferral fee, according to the official registration information.

Before paying, review the latest information about:

  • Registration fees.
  • Refund conditions.
  • Deferral fees.
  • Registration deadlines.
  • Any additional requirements for your test session.

Fees and policies may change between testing cycles, so avoid relying on information from older preparation websites.

Can Singapore Students Take the ISAT Online?

Yes. The official ISAT website states that all ISAT test sessions are conducted through remote proctoring. Candidates complete the test using a suitable computer and meet the relevant technical and testing requirements.

Before test day, candidates should prepare:

  • A suitable computer or laptop.
  • A stable internet connection.
  • An acceptable photo-bearing identification document.
  • An erasable whiteboard and pen, or permitted scratch paper and stationery.
  • A mirror or another approved reflective device.

Mobile phones and tablets are not supported for taking the test. Candidates should review the official test-day instructions for the complete list of requirements and prohibited items.

When Should Singapore Students Take the ISAT?

There is no single test date that is suitable for every student. The best timing depends on your university application deadlines, preparation level and target programmes.

When choosing a test window, consider:

  • University application deadlines: Confirm when your ISAT result must be available.
  • Preparation time: Allow enough time to understand the test format and practise both reasoning sections.
  • Academic commitments: Consider school examinations, coursework and other application requirements.
  • Test availability: Check the available test windows and registration deadlines.
  • University requirements: Some universities may require specific minimum scores or have their own application timelines.

For students applying for the 2027 university intake, the relevant ISAT test date may depend on the university and applicant category. For example, Monash provides different deadlines for different educational pathways, while UNSW states that international applicants should complete the ISAT by the relevant application deadline.

The most important step is to plan backwards from your application deadline rather than choosing a test date without considering the rest of your application.

How Should You Prepare for the ISAT?

Preparing for the ISAT requires more than memorising information. Since the test focuses on critical and quantitative reasoning, your preparation should involve understanding question types, practising how to interpret information and improving your ability to work efficiently under time pressure.

Here are several steps to help you begin.

1. Understand the ISAT Test Format

Start by learning how the ISAT is structured and what each reasoning section assesses.

Understanding the test format can help you identify which skills you need to practise and reduce the amount of time spent becoming familiar with the assessment during your preparation.

2. Complete a Diagnostic Test

A diagnostic assessment can help you understand your current strengths and weaknesses.

Use your results to identify areas that may require more attention, such as interpreting complex information, identifying relationships or solving quantitative problems.

Your first score should be treated as a starting point for preparation, not a guarantee of your final test performance.

3. Practise Critical Reasoning

Critical Reasoning questions require you to understand and analyse information, evaluate arguments and draw appropriate conclusions.

During preparation, practise:

  • Identifying the main idea of a passage.
  • Distinguishing facts from assumptions.
  • Evaluating the strength of an argument.
  • Drawing conclusions from the information provided.
  • Working with unfamiliar topics and passages.

Focus on understanding why an answer is correct rather than simply memorising question patterns.

4. Develop Quantitative Reasoning Skills

Quantitative Reasoning involves analysing information and solving problems using mathematical and scientific contexts.

Your preparation may include practising:

  • Interpreting numerical information.
  • Identifying relevant data.
  • Applying mathematical concepts.
  • Estimating and comparing values.
  • Solving problems efficiently.

You do not need to focus only on completing questions quickly. Build accuracy first, then gradually work on improving your speed.

5. Review Your Mistakes

Reviewing incorrect answers is an important part of preparation.

After completing a practice set, consider:

  • Did you misunderstand the question?
  • Did you miss important information?
  • Did you use an inefficient approach?
  • Did you make a calculation error?
  • Did you run out of time?

Keeping track of recurring mistakes can help you develop a more focused study plan.

6. Practise Under Timed Conditions

The ISAT is a three-hour assessment, so practising under time constraints can help you become more comfortable working efficiently.

Begin with untimed practice if you need to understand the question types. As your preparation progresses, introduce timed practice and full-length simulations.

Try to create testing conditions that are similar to the actual assessment, while following the official test instructions.

7. Use Reliable Preparation Materials

Start with the official information and preparation materials provided by ACER. You should also evaluate third-party resources carefully and avoid assuming that every preparation course or practice question reflects the actual ISAT.

If you choose additional support, consider whether the programme provides:

  • A clear preparation structure.
  • Practice questions relevant to ISAT reasoning skills.
  • Feedback on your performance.
  • Guidance on managing time.
  • Support tailored to your starting level and preparation goals.
