Glazier
No state licenses individual glaziers. It's a registered-apprenticeship trade, typically four years and 8,000 hours through the Painters and Allied Trades, and that certificate carries nationwide without a transfer process. The line that matters is the same one running through every finishing trade here: work for someone else's licensed outfit and you need nothing, but contract directly with customers and glazing may require a specialty contractor license.
Where can I take my glazier license?
Pick the state you're licensed in. You'll get the states that will consider that license — which is not the same as a free transfer.
FAQ
Do I need a license to install glass?
Not as an employee — no state licenses individual glaziers anywhere. Contracting directly is the different question, and California is the clearest example: it issues a C-17 Glazing specialty classification, so a glazing business needs that or a general building license, while the glaziers working under it need nothing. Elsewhere glazing usually folds into general contractor licensing, which means the threshold and rules are whatever your state sets for contractors generally. Your apprenticeship certificate stays portable throughout — it's the business credential that's state-bound, not you.

Alabama
No license — state or localNo license exists for this trade at any level — state or local — in this state.
No state license for individual glaziers. Registered apprenticeship, typically 4 years / 8,000 hours OJT plus classroom instruction (IUPAT is the largest sponsor). High school diploma or GED is the typical entry requirement. Glazing CONTRACTORS may need a state specialty contractor license - see this dataset's carpenter record for the state'S general contractor licensing structure and thresholds.
Alabama does not license glaziers - no US state does. This is a registered-apprenticeship trade, and the credential that travels is your U.S. Dept. Of Labor apprenticeship completion certificate, which is federally registered and valid nationwide. There's no reciprocity question here because there'S no state license to transfer. Note that a glazing contractor - as opposed to an employed glazier - may need a state specialty contractor license.
What applies instead: Because Alabama issues no glazier license, there is no state credential to reciprocate. The DOL-registered apprenticeship certificate is portable nationwide by design - it is a federal registration, not a state one.

Wisconsin
No license — state or localNo license exists for this trade at any level — state or local — in this state.
No state license for individual glaziers. Registered apprenticeship, typically 4 years / 8,000 hours OJT plus classroom instruction (IUPAT is the largest sponsor). High school diploma or GED is the typical entry requirement. Glazing CONTRACTORS may need a state specialty contractor license - see this dataset's carpenter record for the state'S general contractor licensing structure and thresholds.
Wisconsin does not license glaziers - no US state does. This is a registered-apprenticeship trade, and the credential that travels is your U.S. Dept. Of Labor apprenticeship completion certificate, which is federally registered and valid nationwide. There's no reciprocity question here because there'S no state license to transfer. Note that a glazing contractor - as opposed to an employed glazier - may need a state specialty contractor license.
What applies instead: Because Wisconsin issues no glazier license, there is no state credential to reciprocate. The DOL-registered apprenticeship certificate is portable nationwide by design - it is a federal registration, not a state one.
