What it validates, who it is written for, and the experience it assumes.
The ISTQB® Certified Tester Model-Based Testing (CT-MBT) certification focuses on an advanced test approach that uses models to support the test process. It extends and supports classic test design techniques such as equivalence partitioning, boundary value analysis, decision table testing, state transition testing, and use case testing. By leveraging models, testers can improve the effectiveness and efficiency of their testing efforts, making this an innovative approach for modern software delivery.
This certification equips you with the skills to collaborate in a model-based testing team using standard terminology and established MBT concepts, processes, and techniques. You will learn to apply and integrate MBT into a test process, effectively create and maintain MBT models, and select, create, and maintain test artifacts from those models, considering the risk and value of the features tested. Ultimately, you will be able to support your organization in improving its quality assurance process to be more constructive and efficient.
The Model-Based Testing certification is aimed at testers, test analysts, technical test analysts, test managers, system and software developers, and architects. It is also beneficial for anyone who wants a deeper understanding of software testing and of the use of models for test generation, such as project managers, quality managers, product managers, business analysts, and business process experts. This certification is designed for professionals who are involved in the test process and want to adopt a more systematic, model-driven approach to testing. It is particularly valuable for those who need to improve test coverage, manage test complexity, and align testing with business requirements.
While not mandatory, ISTQB recommends that candidates have a solid understanding of software testing fundamentals and practical experience in test design and execution. The CT-MBT certification builds on the concepts covered in the Foundation Level. Familiarity with basic test design techniques such as equivalence partitioning, boundary value analysis, and state transition testing; Experience in creating and executing test cases in a structured testing environment; Understanding of the fundamental test process and software development lifecycles; Basic knowledge of modeling concepts and notations is helpful but not required

In front of every objective the practice pages are already there, free and without an account. This is one objective, opened.
25 questions on this objective, five to a page. Every range above is a real page, open now, with no account.
The curriculum tells you what is on the exam. Proving you know it is a different job — and it is the one the closed-book run does.
The whole bank is open. 5 questions to a page, every answer explained, and a discussion thread on each one.
Every objective, and every page range, is a link — so you can pick up exactly where you left off.
Short enough to finish, long enough to matter.
Not only which one is right — why the others are wrong.
Ask, answer, and vote. Every question has its own thread.
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.

The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.

Where the exam is defined, scheduled and scored.
We link to them rather than repeat them, so nothing here goes stale behind them.
We build from the official skills outline, not from a summary of it — 29 objectives, 169 concepts written under them, and free questions against every one. When ISTQB changes the outline, this page changes with it.
That is the only question worth answering the night before, and no link answers it. You answer it by taking the questions with the book closed, and seeing what comes back.
