The Structure group of the Analyst Resource Center periodically reviews the structure of the WID, and makes modifications when they feel it is appropriate to do so.  When modifications occur, a new version of the WID is created. While states are required to update their WID to the latest version, we realize that the transition to newer versions can take time. Therefore, the ARC will maintain documentation and provide support for the current and past two versions of the the WID. Below you will find links to the file structure, file information and data directories.
