It specifies the information and narrative required to confirm that the project complies with the Credit Criteria. The Submission Template will ask project teams to justify their claims with evidence that must be included in their submission.

Submission Templates are provided in MS Word format. There are no automated or 'smart' features embedded within these Submission Template.
