Classification C-23
California C-23 — Ornamental Metal Exam Prep
California Ornamental Metal (C-23) applicants take two California exams: the shared Law & Business exam and the C-23 trade exam. We prep you for both.
Ornamental Metal question bank is being built
The C-23 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-23 and we'll email you the moment it's live.
