Admission criteria and process

Criteria for membership

In addition to considering the reputation of a prospective firm and its adherence to the highest professional standards, Grant Thornton has developed a set of criteria that must be met by prospective member firms before they can be considered for membership in the organisation. The criteria for membership include:

  • member firms must adopt Grant Thornton policies, procedures and methodologies. These include, but are not limited to:
    - service line methodologies and quality controls, including client acceptance and reacceptance
    - engagement protocols 
    - ethical and independence policies
  • member firms must maintain a system of quality control in accordance with International Standards on Quality Control (ISQC) 1, and must agree to periodic quality assurance inspections by global teams.


Before acceptance of a new member firm, Grant Thornton performs due diligence to determine whether the criteria for membership are met. Admission as a member is dependent on the outcome of this due diligence and the execution of the Grant Thornton Member Firm Agreement and Name Use Agreement. Member firms must abide by all current Grant Thornton policies and standards. All member firms are subject to the same global monitoring policies, procedures and practices.
