Thinking Skills Assessment (TSA): A Complete Guide for Oxford Applicants

Updated: [December 25], [2025]  |  [5] min read

The Thinking Skills Assessment (TSA) is an admissions test used by the University of Oxford for a range of competitive undergraduate courses.

Rather than testing subject knowledge, the TSA focuses on how well candidates can think, reason, and communicate ideas clearly.

It is designed to stretch strong applicants and help admissions tutors identify students with excellent problem-solving and critical thinking skills.

Understanding how the TSA works is an essential first step in preparing effectively and approaching the test with confidence.

What Is the Thinking Skills Assessment (TSA)?

The Thinking Skills Assessment (TSA) is an admissions test used by Oxford University to assess how applicants think, rather than what they know. The test is divided into two distinct sections and is taken on a computer at an authorised test centre.

Section 1 is a multiple-choice assessment lasting 90 minutes. It consists of 50 questions designed to evaluate problem-solving skills, including numerical reasoning, as well as critical thinking skills such as understanding arguments and assessing reasoning expressed in everyday language.

Section 2 is a 30-minute writing task. This section is only required for applicants to Philosophy, Politics and Economics (PPE). Candidates choose one question from a choice of three and write a short essay.

The questions are not subject-specific and are designed to assess how clearly and logically ideas are organised and communicated in writing.

Which Courses Require the TSA?

The Thinking Skills Assessment is required for several undergraduate courses at Oxford University, but the sections you take depend on the course you are applying for.

Applicants for Philosophy, Politics and Economics (PPE) are required to take both sections of the TSA. This includes the multiple-choice thinking skills assessment and the writing task.

For all other courses that use the TSA, applicants are required to take Section 1 only. These courses are:

  • Economics and Management

  • Experimental Psychology

  • History and Economics

  • Human Sciences

  • Psychology, Philosophy and Linguistics

It is important to check the requirements for your chosen course carefully, as taking the correct sections of the TSA is a mandatory part of the application process.

How to Register for the Thinking Skills Assessment?

To take the Thinking Skills Assessment, candidates must register through the Oxford Admissions Test registration portal.

Registration is a required step for all applicants whose course uses the TSA and cannot be completed without a UCAS ID. As long as you have started a UCAS application, you will already have this ID, even if you have not yet submitted your application.

During registration, applicants will be asked to select their course using the relevant course code and confirm that all details entered are correct.

This information is used to match your test registration with your UCAS application, so accuracy is essential.

If you require access arrangements, such as extra time or rest breaks, these must be requested during registration.

Supporting evidence from a medical or educational specialist must be uploaded at this stage. Requests are reviewed before booking, so candidates needing access arrangements are strongly advised to register as early as possible.

Booking Your TSA Test at a Pearson VUE Centre

After completing registration, candidates must book their Thinking Skills Assessment at an authorised Pearson VUE test centre.

The TSA is delivered on behalf of Oxford University and must be taken in person at one of these centres. Test centre availability is limited, and places are allocated on a first-come, first-served basis, so booking early is strongly recommended.

When booking, candidates can choose their preferred test centre location and appointment time. The booking system will suggest centres based on the address linked to your account, but you can search for alternative locations if you expect to be away from home.

Once your booking is confirmed, Pearson VUE will send a confirmation email containing your test date, appointment time, and directions to the test centre. These details will also be available in your Pearson VUE dashboard.

How to Prepare for the Thinking Skills Assessment?

The Thinking Skills Assessment is designed to be challenging, with time pressure being one of the main difficulties, particularly in the multiple-choice section.

As candidates must answer 50 questions in a limited amount of time, tutors emphasise the importance of managing pace carefully. Practising under timed conditions helps applicants become comfortable making decisions quickly and moving on when a question proves difficult.

Candidates are advised to select an answer for every question, even if it requires an educated guess, as there is no penalty for incorrect responses. Flagging challenging questions and returning to them later can help avoid spending too long on any one problem.

For PPE applicants, effective preparation for the writing task includes planning responses before writing. Clear structure, concise arguments, and accurate wording are more important than length.

What to Expect on Test Day

The Thinking Skills Assessment is taken in person at an authorised Pearson VUE test centre. Candidates are advised to arrive early to allow enough time for check-in and security procedures.

You will be required to present acceptable identification, and the name on your ID must match the details on your test registration.

Personal belongings are not permitted in the testing room and must be stored in a locker. During the test, you will be provided with laminated note boards and a pen for calculations and planning, which must be returned at the end of the exam. Rough paper is not allowed.

Before starting the test, candidates must agree to a non-disclosure agreement. Throughout the exam, the on-screen timer shows the remaining time, and tools such as question flagging and answer review are available.

Once finished, you submit the test on screen and exit the platform under staff supervision.

What Happens After You Finish the Assessment?

Results from the Thinking Skills Assessment are sent directly to Oxford admissions tutors and are used as part of the shortlisting process. Tutors consider TSA performance alongside the UCAS application and other submitted materials when deciding which candidates to invite to interview.

Applicants do not receive their scores immediately. Test results are shared with candidates after college decision letters have been sent. Applicants may also contact their college to request feedback on their performance if they wish.
