Classification C-17

California C-17 — Glazing Exam Prep

California Glazing (C-17) applicants take two California exams: the shared Law & Business exam and the C-17 trade exam. We prep you for both.

Glazing question bank is being built

The C-17 trade bank isn't published yet, so we're not charging for it. Law & Business — required for every classification — is ready today. Join the waitlist for C-17 and we'll email you the moment it's live.
