CCT practice questions - frequently asked questions

Plain answers about how CCT Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real CCT exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CCT exam spans 5 domains: General Metrology (24% of the exam); Measurement Systems (20.8% of the exam); Calibration Systems (22.4% of the exam); Measurement Uncertainty and Applied Math (20% of the exam); Quality Systems and Standards (12.8% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: General Metrology 24%; Calibration Systems 22.4%; Measurement Systems 20.8%; Measurement Uncertainty and Applied Math 20%; Quality Systems and Standards 12.8%.

To earn the CCT you pass its certification exam, which covers General Metrology (24%), Measurement Systems (20.8%), Calibration Systems (22.4%), Measurement Uncertainty and Applied Math (20%), and more, then maintain the credential per the issuing body's rules. Consistent timed practice across every domain, reviewing what you miss, is the most dependable preparation — start with the free questions above.
