How to use the BIA
Step 1: Set up
Begin by completing your Assessment Setup to create a customised assessment based on your company’s size, industry, and location.

Identify, track, and learn about improvement opportunities and best practices over time. Whether you're pursuing certification or simply looking to set and track targets, the BIA is designed as an ongoing tool you can return to as your business evolves.

Additional requirements for B Corp Certification
The BIA is composed of Foundational Requirements and Impact Topic Requirements. If you are pursuing B Corp Certification, both must be completed in full.
You will also need to complete a confidential Disclosure Questionnaire — declaring any sensitive practices, fines, or sanctions related to your company or partners, and meet the B Corp legal requirement, which commits your company to considering the impact of its decisions on all stakeholders, not only shareholders. Once complete, your assessment is submitted for independent verification by B Lab's Standards Team.
