Interpretations from 2019 on are found in the table below. All prior interpretations can be viewed as a pdf: CHPS Criteria Interpretation Archive.
Interpretations may be formal (reviewed by our National Technical Committee) or informal (reviewed by a member of our technical team), depending on the substance. They may be submitted using the Request Form below or via Basecamp, our project management site. Criteria Interpretations range from unique situations requiring a case-by-case application of the criteria to clarifications applying to all projects. Registered CHPS Verified projects may request up to two Criteria Interpretations free of charge. Each additional CCI is $250 for non-members and $200 for CHPS members.
CHPS Designed projects and non-registered projects may also request interpretations at a rate of $200 per interpretation for members and $250 for non-members.
