In plain terms. VAAR is the Department of Veterans Affairs' supplement to the FAR, adding VA-specific contract rules.
Who it applies to. Contractors serving the VA, especially in health care and IT.
What it requires. Comply with the FAR, then VAAR additions. VA work commonly involves veterans' protected health information and personal data, so expect privacy, information-security, and records-handling requirements tied to that data.
Why it matters. The VA holds vast amounts of sensitive personal and health information, making data protection a central contract obligation.
Citation. VAAR, the Veterans Affairs Acquisition Regulation supplement to the Federal Acquisition Regulation (FAR), codified in the FAR System at Title 48 of the C.F.R.
