Why ISI exists and what we work towards

Our vision

A world where every scaffold is built, inspected and signed for by people whose competence can be proven, so that nobody is hurt working at height.

Our mission

To set clear, independent competence standards for scaffolders, supervisors, inspectors and instructors; to authorise and audit the centres that train them; and to make every ISI certificate verifiable by anyone, in seconds.

What we value

• Honesty. A certificate only says what the assessment proved.
• Trust. Decisions are independent, consistent and open to appeal.
• Quality. Standards, centres and assessors are reviewed and improved continually.

How we measure ourselves

• Employers can check any certificate before work starts.
• Authorised centres pass regular, evidence-based audits.
• Complaints and appeals are answered on time and used to improve.
