The Digital Accessibility Maturity Model provides a clear and concise method for measuring the development of accessibility programs. The model is split into ten core dimensions that define high level areas of activity or competence needed to be addressed for an effective digital accessibility program to be in place. These dimensions are, in turn, divided into a set of aspects - essentially, divisions used to break down large dimensions into specific sub-categories. Each aspect must be mastered in order to ensure that a program is successful and mature. Maturity level is rated along five progress levels of process maturity, moving from level one - a lack of defined process - to level five a continuously improving process.
