Stage One

The TSP prepares an outline "Specification of Service Subject to Assessment" (S3A). This provides a high-level description of the service to be submitted for approval, and lists the relevant Approval Profiles for the type of service approval sought. A more detailed version of the S3A will br required later, which will then form the basis of the contract between the TSP and the tScheme-recognised assessor. A Model Specification is available in the library, in the "supporting documents" section, entitled 'Model S3A' (document ref. tSd0230).

The TSP selects a tScheme-recognised assessor (for list click here), accredited for the performance of assessments using the tScheme Approval Profiles.
