ISTQB CT-PT study guide
ISTQB CT-PT · Work through your exam, one topic at a time.
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. The ISTQB CT-PT study guide has 4 sections and about 1,378 words.
01Performance Testing Fundamentals (basic concepts)
Performance Testing Fundamentals covers the vocabulary and purpose of performance testing: why it is a non-functional test type, how it differs from functional testing, the main test types, and how performance risk drives test design. The exam checks whether you can choose the right test type for a stated risk, not just recite definitions.
366 words, about 2 min02Performance Measurement and Metrics
This domain covers measurement: response time, throughput, utilization, concurrency, think time, error rates, and percentiles. The exam tests whether you can define a metric precisely and interpret it without being misled by averages or tool defaults.
344 words, about 2 min03Performance Testing Activities and Tasks
Performance Testing Activities and Tasks covers the performance test process from planning through reporting: objectives and KPIs, workload modeling, scenario design, scripting, execution, monitoring, analysis, and exit criteria. The exam tests sequencing and deliverables.
337 words, about 2 min04Performance Testing Tools and Organizational Aspects
Tools and Organizational Aspects covers tool categories and selection, tool implementation, roles, governance, skills, and environment and data ownership. The exam tests practical judgment about fit, cost, and organizational readiness.
