About GRC
We've been on the auditor's side of the table.
Every instructor at GRC is a former federal auditor, OIG analyst, or program officer. We built GRC because grantees deserve training from people who know what auditors are actually looking for when they open your files.
What we stand for
Compliance training that is
backed
Every session is built from current compliance data. We know which compliance requirements matter most right now, and that is what we teach.
led
Every instructor has worked inside the compliance process, on the auditor's side of the table. They teach from that perspective.
tested
Our frameworks, checklists, and toolkits come from real single audit fieldwork. Built around what auditors actually test.
enough
We give grantees the exact documentation standards, internal controls, and policy language that match each compliance requirement.
We've conducted single audits across the country. We know what compliance gaps look like in practice. Now we teach grantees how to close them.

See open roles →How we approach training
We want grantees to understand exactly what auditors are testing, why, and what their documentation needs to show — with enough specificity to act on it.
We start with what auditors actually look for
Every session is built backward from current compliance data. We analyze compliance requirements and documentation patterns to identify where organizations face the most risk.
We teach from the auditor's checklist
Federal auditors work from compliance checklists. We walk grantees through those checklists so they know what documentation is being requested, what is being tested, and what a gap looks like from the other side of the table.
We stay specific
We give grantees the exact documentation language, control structures, and policy requirements for each compliance area. That specificity is what prevents the same compliance issues from recurring.
Partnerships
We encourage our compliance community to grow
