Assessor Qualifications

tScheme has agreements with Accreditation Bodies to determine, as part of their accreditation process, whether Certification Bodies (Assessors) have the necessary skills and qualifications to be able to carry out assessments of TSPs against the Approval Profiles.

Details of how each accreditation body determines these qualities is specific to each body and further information is available under the relevant entry in the Directory of Recognised Accreditation Bodies (see here).

External Standards and Guidelines

tScheme originally worked with the Government in producing two documents that were to be used in the registration process for the Government’s Gateway project. These were “Guidelines for the Verification of Identity of Organisations” and “Guidelines for the Verification of Identity of Individuals”.

Following consultation during 2002, the Government produced their requirements based on these documents: “HMG’s Minimum Requirements for the Verification of the Identity of Individuals v2.0” and “HMG’s Minimum Requirements for the Verification of the Identity of Organisations v2.0”

Subsequently these were replaced by 'Good Practice Guides’. GPG45 for Individuals and GPG46 for Organisations. These guides, and GPG45 in particular, are the basis for the UK Government's Verify program.

These documents are recognised by tScheme and any TSP undergoing an Assessment leading to Approval against the Registration Profile (tSd0042) or the Identity Services Profile (tSd0108) can ask their Assessor to assess them against either or both of these requirements documents as part of their tScheme Assessment.
