Three assessment types are available, offering increasing levels of confidence in the assessment outcome.
Self-assessment
The self-assessment is completed by the facility and is based on self-declaration against the applicable requirements. Supporting evidence does not need to be submitted as part of the assessment, although the facility should have and retain evidence to substantiate its responses.
Third-party desktop assessment
The desktop assessment is conducted remotely by a ZDHC Approved Supplier to Zero Assessor. The assessor reviews the facility’s responses and the supporting documentation submitted for all criteria claimed as met.
The outcome reflects the assessor’s evaluation of the information and evidence available at the time of assessment.
Third-party on-site assessment
The on-site assessment includes the document review undertaken during a desktop assessment and an on-site evaluation of the facility.
The assessor verifies implementation through activities such as interviews, site observations, document and record reviews, and inspection of relevant processes and operational areas. The on-site assessment provides the highest level of confidence in the assessment outcome.
Second-party on-site assessment is another assessment type that is planned for future development.
