PES's history dates back to 1941, when it originated as a testing department of the American Public Health Association (APHA). As an APHA testing department, PES focused on providing examinations for health professionals employed by state and local civil service agencies. Early in its history, PES began to expand our client base to include organizations that license and certify health and allied health professionals on a national basis. PES's clients span a wide range of professions, industries, and skill levels including the business, industrial, and government sectors. PES's history has been marked by continuous improvement in technology, methodology, mission definition, and quality of service. |
