Their accreditation standards are periodically revised to reflect the dynamic, changing environment of medical transport with considerable input from all disciplines of the medical profession." Other states require either CAMTS accreditation or a demonstrated equivalent, such as Rhode Island and Texas, which has adopted CAMTS' Accreditation Standards (Sixth Edition, October 2004) as its own. In Texas and Maryland, an operator not wishing to become CAMTS accredited must submit to an equivalent survey by state auditors who are CAMTS-trained. An exception would be the Maryland State Police, who are not accredited. Virginia, Arizona, Missouri, and Oklahoma have also adopted CAMTS accreditation standards as their state licensing standards.
