Assurance principles

ASI‘s assurance model aligns with the principles outlined in the ISEAL Alliance Code of Good Practice: Assuring Compliance with Social and Environmental Standards (“ISEAL Assurance Code”).

The ISEAL Assurance Code sets out the following principles that ASI has adopted as key to enhancing conformity with standards and instilling trust in an assurance system:

  • Consistency: to ensure replicable results
  • Rigour: the ‘intensity’ of the assurance process that best enhances accurate results
  • Competence: of individuals carrying out assurance, to interpret and apply intent of the standards
  • Impartiality: to ensure fair and objective treatment of organisations seeking certification
  • Transparency: to provide for stakeholder scrutiny and build confidence
  • Accessibility: affordable, culturally sensitive, comprehensible and within reach of target clients
