Del. Code tit. 24 § 1714
The amount of a fee imposed under this chapter by the Division of Professional Regulation must approximate and reasonably reflect the reasonable projected costs of services or activities provided by the Board, as well as the proportional expenses incurred by the Division for services or activities provided on behalf of the Board. A separate fee may be charged for each service or activity, but a fee may not be charged for a purpose not specified in this chapter. The application fee for a certificate to practice medicine, or for a certificate, license, or other authorizing document to practice any other profession or occupation regulated by this chapter, may not be combined with any other fee or charge. At the beginning of each licensure biennium, the Division, or another State agency acting in its behalf, shall compute and set the fee for each separate service or activity that the Board or the Division expects to provide during that licensure biennium.
