Teachers Mutual Bank Limited’s B Corp score is 102.4


B Corp Certification is a rigorous, verified performance assessment across 5 areas: Governance, Workers, Customers, Community and Environment.

Companies that become Certified B Corporations must score at least 80 points out of 200.

Most companies score between 40 -100.  

The median score of all completed B Impact Assessment (BIAs) is 55.

The average score for Certified B Corporations in Australia and Aotearoa New Zealand region is 96.

The B Impact Assessment involves more than 300 scored questions, multiple verification rounds, a series of interviews and data provision. The process took us over 12 months to complete. Companies undergo a multi-step verification and must meet certain transparency requirements.

Once certified, each B Corp must make its B Impact Report transparent on, allowing the public to see the areas in which specific companies excel and compare B Corps' scores against the performance of mainstream businesses.
