Rules & Requirements

The VCS Program rules are the backbone of the program. They define the standards and processes which all projects must follow in order to be certified. The VCS rules are set out in a suite of documents which include four types of program documents Requirements, Procedural, Templates,  and Guidance.

Documents are updated periodically. Please check this page to be sure you are using the latest version of a given document.

For a running  a running catalogue of all updates, see the Updates to the VCS Standards Version 3.
