This document provides a brief description of the context for, and use of, the European Training Foundation (ETF) Financing Prism, and includes a call for evidence regarding the development and implementation of vocational education and training (VET) financing policies, as well as the use of the prism itself. The components of the prism are described in detail, and a series of steps is outlined which can be used to organise the policy dialogue. This document concludes that the critical success factors are familiarity with the ETF Financing Prism, forward planning, and a steady level of political will.
