After creating your user account or logging into the DELPROS online portal, you may begin your application for licensure to take the required exam(s).

When the Board has reviewed and approved your application, you will receive an email notification stating you have been approved to sit for the exam with your candidate information and registration form.

  • Click on the titles below in each section to expand the information.

The Division of Professional Regulation utilizes the external testing vendor, ProV Exam (ProV), to facilitate all the required licensure examinations for the Plumbing & HVACR trade, and the external testing vendor, Associated Builders and Contractors Delaware (ABC Delaware), for the “Apprenticeship-By-pass” examination for both trades should the Board also require this examination for licensure.

Associated Builders and Contractors Delaware:

Upon receiving Board-approval to sit for the “Apprenticeship By-Pass Examination,” Board staff will contact you by email and include all of the information you will need in order to call to schedule and prepare for your examination:

  1. NCCER Catalog Information
  2. NCCER Plumbing/HVACR materials
  3. Plumbing/HVACR Study Guide
  4. Plumbing/HVACR Approval Letter (includes ABC Delaware’s contact information to schedule your exam)

After taking your examination, the external testing vendor, ABC Delaware, will send us your test results. Once passing results have been received and verified, Board staff will forward the passing candidate’s registrations, to the testing vendor, ProV, who will contact you via a ProV email address within the next 1 – 2 weeks to provide you with the licensure examination information described in the section below.

You must obtain a minimum score of 70% to pass the exam. Should you require another attempt at the “Apprenticeship By-Pass” examination or a licensure examination, you may contact ABC Delaware or ProV directly, as detailed in the examination information materials originally issued to you for your initial examination. It is important to be aware that Regulations 2.2.2 and 3.1.6, state that Plumbing and HVACR applicants who do not receive a passing score after three (3) attempts must reapply as a new applicant and obtain the Board’s approval to sit for the licensure examination once again. You may not reapply until one (1) year has passed from the date you last took your examination.

Allow up to two weeks for the Board office to receive your official examination score. After the Board office receives your passing score and validates that you have met all Plumbing Licensure or HVACR Licensure requirements, your license will be issued.

You will receive an email notification stating that your license has been issued and will contain additional details about your license renewal and/or continuing education requirements.
