To certify as a B Corp, a company must achieve a minimum verified score of 80 points on the B Impact Assessment. The B Impact Assessment asks questions about how the day-to-day operations of a company create positive impact for the company’s workers, community, and environment. Additionally, companies can earn further points if their overall business model can be shown to create positive social and environmental impact as well, qualifying the company for specific Impact Business Model points.

Scores for Certified B Corporations are verified by the non-profit B Lab.

The questions in the B Impact Assessment are organized into five Impact Areas: Governance, Workers, Community, Environment, and Customers. Click into a Impact Area to see topics covered in each. Topics in blue are Impact Business Models associated with that Impact Area where the company has earned additional credit. Due to rounding, displayed totals may not add up exactly.

The B Impact Assessment is customized to a company's size, sector, and geographic market.  However, within those parameters, there are still questions included in the B Impact Assessment that might not be relevant to a particular company. In cases where a question is not applicable, the potential points available for that question are instead earned based on the performance of the company on the other topics relevant to the stakeholder and summed up as "N/A points." Likewise, a score of N/A for Workers means that the company is a sole proprietor or partnership with no full-time staff, and a score of 0 or N/A for Customers means that the company does not have a specific Customer-focused Impact Business Model.
