Certification under the Scheme is available, without restriction, to all applicants who satisfy the certification requirements. Certification to the scheme is available in the following grades, depending on the individual assessment experience:

• Provisional Assessor This is the entry or training grade, for the assessor who has the appropriate personal attributes, academic, professional and technical competencies but lacks the required assessment experience.
• 
  
• Competent Assessor This grade applies if the assessor meets minimum requirements for assessment experience. The assessor will be able to lead assessments either individually or as leader of an assessment team.
• 
  
• Principal Assessor This grade applies to assessors that have extensive assessment experience and have led assessments as leader of assessment teams comprising two or more persons. Principal assessors will normally be working as consultants, for or on behalf of procurement organizations or certification bodies (registrars). Principal assessors are allowed to educate and train other assessors.
