In 2019, ISEAL carried out a review of the Credibility Principles to determine if they require revision, understand how they have been used and adopted, ensure the best approach to communicating them to meet stakeholder needs, understand changes in the landscape and trends, and understand usability of the principles and any possible changes to scope or objectives

This document outlines the findings from the review, which determined that there is a need to revise the Credibility Principles in 2020.
