TSI practice questions - frequently asked questions

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

The TSI exam spans 8 domains: Project Safety (13% of the exam); General Work Practices and Communication (7% of the exam); System Materials (10% of the exam); Tools and Equipment (6% of the exam); Materials Installation (27% of the exam); Membrane Seaming (22% of the exam); Flashings and Accessories Installation (11% of the exam); Job-Site Housekeeping (4% 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: Materials Installation 27%; Membrane Seaming 22%; Project Safety 13%; Flashings and Accessories Installation 11%; System Materials 10%; General Work Practices and Communication 7%; Tools and Equipment 6%; Job-Site Housekeeping 4%.
