Both ASPPH and APHA established task forces on the credentialing of public health workers in the late 1980’s, stimulated in part by the call from the U. S. Surgeon General for such an effort.

Formal Study

ASPPH commissioned a formal study of public health worker credentialing in 1989, which recommended that if ASPPH did decide to undertake credentialing that it should pursue it independently and in a “pro-active, reformist role.”
