People often assume the ISTQB Technical Test Analyst exam is a programming test. It is closer to a code-reading and judgement paper: you trace short pseudo-code to count coverage, pick a technique for a described project, and weigh security, reliability and performance risks. The CTAL-TTA v4.0 paper has 45 questions in 120 minutes and needs 51 of 78 points, and this roadmap walks through what each of its six chapters asks of you.

Is the Technical Test Analyst paper a coding test, and who is it meant for?
No, but it does assume you can read code. ISTQB's Technical Test Analyst page describes the certificate as a thorough introduction to the technical testing skills many organisations now rely on: risk-based testing, white-box testing, static and dynamic analysis, non-functional testing and test automation. Nothing on the paper asks you to write a program. Instead, you read a ten-line fragment and say how many tests reach 100% decision coverage, or you read a scenario about a payment gateway and say which performance test type answers the stakeholder's worry.
The audience is anyone involved in testing who wants more technical depth: people doing test analysis, test consulting or software development. The prerequisite is the Certified Tester Foundation Level certificate plus enough practical experience, and ISTQB leaves the exact experience rule to each Member Board or exam provider, so confirm it with yours before you pay.
