The Bridge Collaborative is a global change agent driving a fundamental shift in how we think, plan, fund and work across sectors to make bigger change faster.

This document captures a set of principles identified and used by the Collaborative, along with a detailed set of guidance for creating comparable results chains across sectors and evaluating evidence from multiple disciplines in common terms.
