How to Pass TfL Topographical Skills Assessment 2026 – Full Guide

Test length and structure

• Total time is 90 minutes.
• Computer based
• 25 questions

The TfL Topographical Skills Assessment (often called TOPO) is a map-reading and route-planning test for PHV applicants. It checks whether a driver can use an A-Z atlas properly, find locations quickly, and plan legal, sensible routes across London.

How to prepare (and pass first time)

The fastest way to improve is to practise exactly what the test asks you to do: route planning rules, timed MCQs, and A–Z searching speed.

A structured option is the TfL Topographical Course Package, which is a self-study course covering all question types, including route planning practice with video solutions, A–Z question practice, and full mock tests.

You should also practise with the same A-Z edition TfL uses. The 18th Edition A-Z Greater London Atlas is required for practice and is used in the actual test.

During the exam, remember you are allowed to skip questions and return to them later, so do not get stuck too long on one question early on.

One-to-one Topographical training (route planning help)

For students who need extra support (for example, basic English, failed once, or need help using the computer), there is one-to-one Topographical training.

The one-to-one lessons focus on route planning only. They are delivered 100% online in a live classroom with screen sharing, so the instructor can see the screen and guide the student in real time. Lessons are typically one hour each, and many students need around 7 hours total depending on level and progress.

These lessons do not include self-practice access outside of lesson time, so students who want extra practice usually combine lessons with a self-study course.

Question types in details (and what they test)

You will typically see three areas:

Route planning tasks: These check whether you can plan a route between two places using correct rules. Route planning is the most important part of the exam, because it is worth the majority of the marks.

Compass and direction questions: These test basic direction skills (North, South, East, West) and how junctions and roads relate to each other.

A-Z index and map questions: These test whether you can find page numbers, grid references, streets, stations, and points of interest quickly and accurately.

Test format (what happens on the day)

The assessment is a practical, computer-based test. You will use a computer at the test centre and you will also be given an A-Z Master Atlas of Greater London during the exam. It is open book, but sat-nav is not allowed because TfL wants to test real map skills. Pen and paper are not allowed, but you can request a magnifying glass if needed.

The test lasts 90 minutes and contains 25 questions. These are a mix of route planning tasks and multiple choice questions based on compass directions and A-Z index/map reading.

Who needs to take the Topographical test?

Most new PHV driver applicants need to pass the Topographical test, unless they qualify for an exemption (for example, already being a licensed London Taxi driver).

When do you take it?

You usually take the Topographical test after submitting your PHV licence application and before TfL can issue your licence. You book it through your TfL portal once you are invited.

Where is the test held?

The Topographical assessment is held at TfL-approved test centres, and candidates book through their TfL portal account.

Pass mark (and how the marks work)

You need 60% to pass. Not all questions are worth the same.

Route planning carries most of the marks (around 75% of the total). Compass questions are typically worth more than A-Z multiple choice questions, so the best strategy is to treat route planning as the priority and avoid losing easy marks on compass questions.

Attempts and costs

Your first attempt typically costs £36 and a resit costs £16. Candidates usually have two attempts. If both are failed, TfL may require the applicant to restart the licence application process.
