Phone Review:

B Lab staff review questions over the phone that may have been difficult to answer and help companies refine answers so that they better fit the intent of the questions.

Document Review:

Companies and funds submit documents for material questions within the B Impact Assessment. Validation through supporting documentation ensures a greater degree of accuracy.

On-Site Review:

An on-site review is the highest form of validation B Lab provides. This involves documentation review, employee interviews, and a plant/facility walk through.
