How criteria are classified

Required, Recommended, Best Practice.

Every criterion in the framework carries one of three classifications.

Required

Core criteria normally expected to satisfy the relevant Builder Standard assessment area.

Recommended

Processes that demonstrate stronger professional business management.

Best Practice

Processes associated with exceptionally well-managed professional contractors.

Required within Builder Standard does not necessarily mean legally required. It means required to satisfy the relevant Builder Standard criteria. Builder Standard is independent and is not a statutory scheme.

The framework

Assessment, audit and verification decisions are measured against these pillars. Nothing is hidden and nothing is weighted behind the scenes.
