Development Partners
Environmental Health Testing was formed in January 2000 as a partnership between Professional Testing Inc (PTI) and the Chartered Institute of Environmental Health (CIEH).

EHT's flagship product, National Registry of Food Safety Professionals (NRFSP) food safety manager certification, was the first examination created by the company.
The NRFSP program has expanded rapidly to become the second largest food manager certification examination in the United States.
