Of course, every state has its demands. This is for the safety of employers and clients. So, by hiring a licensed plumber you can be sure of his work quality. And as a specialist, you have to keep yourself up-to-date with the latest regulations. Currently, Delaware requires:

  • Being 18 y/o or above

  • 2 years of experience under a supervision of a licensed master: This is acceptable if before that you have already earned a journeyman certificate. If you don’t meet this point you must have a 7-year certified apprenticeship.
  • Presenting proof of passing state-accredited tests in a technical school
  • A statement verifying your disciplinary clear records: This means that there is no pending complaint against you.

Where to apply?

DELPROS designed a virtual platform to accept online applications. Thus, they replaced paper requests to make the steps convenient for applicants. To apply, first, you should create a user account on the website. Here you are able to send a request and check its status.

Once you start you have 6 months to return to your incomplete application and end it up. When everything is ready you should give a $153 fee using your debit card. But don’t pay earlier because payments are non-refundable.

How do I attach files?

Sure, you need to submit the required documents. For this goal you have 2 options:

  • Go to the “Attachments” section and click on “upload”. In this case, you are to have scans of your papers on your computer.
  • Press on “acknowledge”. Thereby, you choose to mail your packet directly to the Board.

DELPROS reviews your documentation and approves or rejects them. Anyways, you will receive a notification about confirmation or refusal. After that, you must visit the office on public meeting days. The schedule is available on the webpage.

Licensing Levels

In Delaware, certification consists of 3 stages:

  • Apprentice- this is for beginners
  • Journeyman- performs only under control of a foreman
  • Master- is an independent specialist

For each of them, you have to take exams to determine your knowledge level.

Training Courses

You can attend practical programs in trade schools and institutions. Yet, remember that you need to select board-approved ones. The educational plan includes:

  • 8000 hours of practice
  • 144-hour theoretical lessons

Many centers suggest online theory classes. Subjects that they teach are:

  • Mathematics
  • Drawing
  • Pipefitting
  • Drafts reading

Undoubtedly, this is the most important part of licensing. When the Board affirms your application you are to register for the exam. It lasts 4 hours and involves 100 multiple-choice questions. Like Florida, here the passing mark is %70 or higher. The participation fee is $141.

Career Opportunities
