Effective 8 March 2011, all projects should use VCS Version 3 requirements. The previous version, VCS 2007.1, may still be used up to and including 8 September 2011. However, all project documents wholly or partially reliant upon the VCS 2007.1 must be issued on or before 8 September 2011.
In some cases, the VCSA may ask a methodology developer to make minor revisions to a methodology. However, all VCS methodologies approved before 8 March 2011 will remain valid until 8 September 2011. If more extensive revisions are required and a methodology must be put on hold, projects may still continue to use the methodology for a grace period of 12 months (for non-AFOLU methodologies) or 18 months (for AFOLU methodologies). The list of methodologies and their status is available on the VCS website.
Where projects are using a VCS methodology, they must use the version of the methodology approved by the VCS. However, where approved VCS methodologies apply or reference VCS Version 3 requirements, projects may apply a methodology deviation to use VCS 2007.1 requirements if the project is validated on or before 8 September 2011.
