CHT practice questions - frequently asked questions

Plain answers about how CHT 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 CHT exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CHT exam spans 5 domains: Patient Care (45% of the exam); Machine Technology (12% of the exam); Water Treatment (15% of the exam); Infection Control (18% of the exam); Education and Professional Development (10% 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: Patient Care 45%; Infection Control 18%; Water Treatment 15%; Machine Technology 12%; Education and Professional Development 10%.
