The Medication Access and Training Expansion Improvement Act, or MATE Improvement Act, aims to clarify and broaden the scope of recognized entities involved in training prescribers of controlled substances. It achieves this by amending Section 303 of the Controlled Substances Act , specifically expanding the list of organizations and educational institutions whose training programs are accepted. Key amendments include adding the American Academy of Family Physicians , the American Podiatric Medical Association , the Academy of General Dentistry , and the American Optometric Association to the list of recognized organizations. Furthermore, it incorporates podiatric medicine into the specified curricula and includes the American Pharmacists Association , the Accreditation Council on Pharmacy Education , and accredited schools of pharmacy among the recognized entities. These changes are designed to ensure a wider range of healthcare professionals and institutions can contribute to the required training for controlled substance prescribing, and they are effective retroactively to December 29, 2022.
