When I think of professional groups, I envision governing boards who help identify educational needs, entry requirements, standards of conduct (professional ethics), and ability to issue or revoke (or recommend) licenses/certifications. Rules, regulations and standards of practice are also part of the mix which a governing board would guide its members.
We are moving towards national accreditation through CAAHEP, at least at the paramedic level, which will help drive the transformation of an occupation to a profession.
The ability to increase educational requirements for all members, national recognition by other health professions, and mobility within will strengthen the movement to become a profession.
After over 40 years of teaching and working as an EMS provider, I have observed many changes in abilities, attitudes of providers as well as acceptance by other health care professions. I believe we are on the cusp of being a professional organization, thanks to many leaders who are taking strives to make it so.
