How Much Does the Master Plumber’s Licensure Exam Cost?
The exam fee varies from state to state but you can expect to pay about $70-$90 altogether. Many states also require an application fee of between $20-$35 in addition to the exam fee.
You should also make sure you meet the prerequisite requirements established by your state’s licensure board. You will need to demonstrate that you have a certain amount of professional experience (anywhere from one to four years) and, in some states, a certain level of education or relevant training.
What Should I Expect on Test Day?
The total number of questions will depend on the state you are applying for licensure in. Some state exams have 80 questions, others have 100. The amount of time you’ll have to answer those questions can range from 2 to 3 ½ hours. Some exams are open book, meaning you can bring approved references into the exam room with you. Others are closed book, meaning you won’t be able to bring any reference material with you while testing.
To get a better sense of exactly how your test day will go, you should make sure to confirm with the licensure board in your state the following details:
- Time allotted for the exam.
- Total number of questions (including any unscored questions).
- Items and reference material that is (and is not) allowed in the exam room.
- Accepted ID formats
No matter where you’re taking the exam, plan to arrive at least 30 minutes prior to the start of your appointment. Doing this will ensure that you have plenty of time to sign in, familiarize yourself with the testing center, and relax before the exam actually starts.
