Those who pass the exam and meet the documentation and auditing qualification requirements can become Provisionally Accredited Assessors, progressing towards full accreditation through mentored assessment experience.
HSA’s network of Accredited Assessors underpins the credibility of HSS certification, providing independent evaluations of projects’ sustainability performance.
