Information on How to Apply for a License in DELPROS

All applications are submitted our online system DELPROS. We no longer accept paper applications.


In order to apply for a license or submit a service request, you must first have a DELPROS user account. To LOG IN or CREATE a DELPROS (Delaware Professional Regulation Online Services) user account:

  1. Go to:
  2. Click GO on the Apply/Manage a License and Service Requests tile.
  3. If you do not have a DELPROS user account, click the REGISTER button on the left side of page for NEW USERS.
  4. If you already have a DELPROS user account, enter your email address and password on the right side for EXISTING USERS and click the LOGIN button.

DELPROS allows you to save your incomplete application and return to it later to finish the process. You only have six (6) months to submit your application once you begin.

  • If you do not submit your application within six months of starting it, you will be required to restart the entire online application again.

You may check the status of your application online throughout the entire application process by using the “View Application Status” feature in DELPROS on your e-License dashboard.


  1. Know the requirements for the license you are pursuing.
  2. Request and gather all documents required to upload on the Attachments page. All information and forms are located on your profession’s webpages.


On the ATTACHMENTS page of your application, you may be instructed to:

  • either “attach” or “upload” the required document(s) directly to your application. This means you will find the document(s) saved on your computer or device and upload it to your application.
  • click “acknowledge.” This means you will either have to mail the documents yourself or request the “third-party” mail the document(s) directly to the Board office.
    • Examples of “third-party forms” are transcripts from schools, employment verifications from a supervisor, and license verifications from another state.
  • Forms requiring a supervisor signature, seal, or notary may have to be MAILED to the Board office directly UNLESS the document specifically indicates to UPLOAD the document.

The requirements for this license type are provided in the following section(s).


In addition to submitting the application and fee in DELPROS, you must submit:

  • Copies of your certificates for 90 hours of QE with test results for each examination.
  • A copy of your high school diploma, or its equivalent. If you do not have a high school diploma or its equivalent, you must have at least two years of assessing experience. To establish your experience, submit one of the following:
    • Official county forms that you signed showing market value change for assessment purposes on a property or groups of properties. You must provide four property documents per year for the past three years.
    • Documents that you signed showing you are responsible for defending an assessment valuation on a property or group of properties before an assessment board or similar entity.
    • Documentation indicating your responsibility in defending an assessment appeal litigation. The documents may be in the form of an appraisal or other document.
