The Uniform Guidance is an effort to by OMB to streamline guidance for the management of federal grant awards and to strengthen oversight of federal funds. To help achieve this, the Uniform Guidance consolidates eight previous OMB publications (called OMB circulars) on federal award management into one central document.
For universities, the Uniform Guidance consolidates and replaces three previous OMB circulars: A-21 (Cost Principles), A-110 (Administrative Requirements), and A-133 (Audit Requirements).
