Knowledge base

The document issued to a facility depends on the type of assessment completed. All Supplier to Zero assessment types are valid for one year from the assessment completion date.

Self-assessment

A facility completing a self-assessment will receive an acknowledgement document confirming completion of the assessment.

The acknowledgement:

  • Is not an independently verified assessment or certification 

  • Does not indicate a Supplier to Zero Performance Level 

  • Should not be presented as certification of the facility’s performance 

Third-party desktop and on-site assessment

A facility completing a third-party desktop or on-site assessment will receive a Supplier to Zero certificate stating:

  • The achieved performance level 

  • The assessment type 

An on-site assessment certificate is valid for one year as standard; however, if the following conditions are met, the validity may be extended:

  • A facility achieving Level 2 may extend the certificate validity once by completing a desktop assessment before the certificate expires. 

  • A facility achieving Level 3 may extend the certificate validity twice by completing a desktop assessment before the certificate expires.
