ExploreAbout this exam
The ISTQB® Certified Tester Performance Testing (CT-PT) is a specialist-level qualification within the ISTQB® portfolio, which the official site describes as the leading global certification scheme in software testing, with 1.5 million exams administered and more than 1.1 million certifications issued in over 130 countries as of May 2025. According to ISTQB®, CT-PT "provides knowledge of the principal aspects of performance testing, including technical aspects, method-based aspects, and organizational aspects," and specifically covers basic concepts, measurements, activities, tasks, and tools. That scope suits testers moving into non-functional work, performance engineers, technical test analysts, architects and developers who must plan, execute and interpret load and stress tests, and test managers who own performance risk in a project. Expect study material organized around four themes of roughly equal weight: performance testing fundamentals, measurement and metrics, activities and tasks across the performance testing process, and tools plus organizational factors such as roles, skills and integration into the lifecycle. To prepare, start from the official CT-PT syllabus and sample exams in the ISTQB® free knowledge base, then look for an ISTQB® accredited training provider or an exam provider in your area. Note that CT-PT is a vendor-neutral knowledge certification; it does not certify proficiency with any specific load-testing tool.
What you'll study
About ISTQB CT-PT preparation
Is CT-PT a Foundation, Advanced or Specialist certification?
It sits in the ISTQB® portfolio as a specialist qualification focused on one discipline, performance testing, rather than the broad Foundation Level. The official page describes it as covering technical, method-based and organizational aspects of performance testing. Check the current syllabus and your local Member Board or Exam Provider for any entry requirements before booking.
What topics does the CT-PT exam cover?
ISTQB® states the certification covers performance testing basic concepts, measurements, activities, tasks and tools. In practice that means terminology and performance risk, metrics and how to interpret them, the activities and tasks of the performance testing process, and tool selection plus organizational roles and skills. The official syllabus in the free knowledge base is the authoritative breakdown.
How many questions are on the exam, how long is it, and what score passes?
The official ISTQB® page retrieved for this profile does not state the question count, duration or passing score for CT-PT, so we do not publish figures. These details are set per exam and published by your Exam Provider. Confirm the current structure with the Exam Provider listed for your country before you schedule.
How much does the exam cost and can I retake it?
Fees and retake rules are not stated on the official ISTQB® page used here, so no figures are given. Pricing varies by country and Exam Provider, and accredited training is usually priced separately from the exam seat. Ask your local Exam Provider directly about cost, rescheduling and retake conditions before paying.
How difficult is CT-PT compared with CTFL?
Expect more depth than Foundation Level. CT-PT assumes you already understand basic testing vocabulary and asks you to reason about performance risk, metric interpretation, workload modelling and tool and organizational trade-offs rather than recall definitions alone. Candidates with hands-on load-testing experience generally find the applied questions easier.
What study order do you recommend?
Work through the official syllabus in its own sequence: fundamentals first, then measurement and metrics, then activities and tasks, then tools and organizational aspects. Attempt the official sample exam only after a full pass, then revisit weak areas. Supplement with hands-on practice on a real system so metric and workload questions feel concrete.
Where can I find training and an exam provider?
ISTQB® maintains a searchable directory of more than 300 accredited training providers and a list of Exam Providers by area, both linked from its official site. Using an accredited provider ensures the course aligns with the current syllabus. You can also browse the Successful Candidate Register to see certified individuals.
What are the most common reasons candidates fail?
Typical failure modes are treating metrics as isolated numbers instead of interpreting them in context, confusing load, stress, soak and spike objectives, ignoring the organizational side such as roles, skills and stakeholder communication, and under-preparing for applied scenario questions. Reading the syllabus learning objectives and practising sample questions reduces these risks.
Does the certificate expire, and is it affiliated with this site?
Validity for CT-PT is not stated on the official page used for this profile, so we do not claim a figure; some other ISTQB® Expert Level certificates are described there as valid for 7 years, but that is not confirmed for CT-PT. This page is independent study material and is not affiliated with or endorsed by ISTQB®.
