Trade and Classification Knowledge: Matching Scope to the Right Louisiana License
What this domain tests
This section tests whether you can read a scope of work and name the LSLBC classification that covers it, and whether you know how each classification's trade exam is applied for, taken, and maintained. Louisiana licenses by classification, not by a single blanket "contractor" title.
How classifications work
- Major classifications include Building Construction; Highway, Street and Bridge Construction; Heavy Construction; Municipal and Public Works Construction; Electrical; Mechanical; Plumbing; and Residential.
- Specialty classifications and the Home Improvement category cover narrower scopes.
- A license authorizes only the work inside its classification. A Building Construction license covers vertical construction, not the roadway, drainage, or water main work that belongs to Municipal and Public Works or Highway.
- Electrical, mechanical, and plumbing scopes require their own classification, qualifier, and trade exam; they are never picked up incidentally by a general building license.
The exams
- The qualifying party takes a trade exam for each classification, plus the Business and Law exam for the firm's first license.
- Exams are proctored, closed-book, multiple-choice, and built from the published content outline for that classification, which references the codes and standards used in that trade.
- You must be approved by the Board before scheduling. Adding a classification means passing that trade exam, filing the application and fee, and meeting the financial review for the limit you want.
- Higher contract limits require a higher level of financial statement, so a firm can pass the exam and still be capped below the job size it wants.
Worked example
A firm holding only Building Construction bids a $400,000 school project that includes a parking lot, storm drainage, and a water main extension. The building itself is covered, but the site utility and roadway scope is Municipal and Public Works or Highway work. The firm either adds that classification with a qualifier who passes the exam, or subcontracts that scope to a properly licensed firm. The bid must also carry the firm's license number.
Traps
Assuming one qualifier covers every classification; bidding before the license is actually issued; letting a qualifier leave without notifying the Board and replacing that person; exceeding the contract limit; and treating a subcontractor's electrical license as covering the prime's scope.
