CMMC-RP study guide
CMMC-RP · Work through your exam, one topic at a time.
The CMMC Registered Practitioner (CMMC-RP) is a professional credential in the CMMC ecosystem, positioned alongside assessors, instructors, and other CMMC professions. The Cyber AB describes itself as building trust and confidence in the CMMC Ecosystem, and its site lists CMMC Professions as covering "Assessors, Practitioners, Instructors, and more." This makes the Registered Practitioner track relevant to individuals who support defense contractors in understanding and preparing for CMMC requirements rather than performing certified assessments. The CMMC-RP study guide has 4 sections and about 1,748 words.
01CMMC Ecosystem and Governance
This domain tests whether you know who owns, runs, and enforces the CMMC program, and how the pieces fit together: DoD policy, the 32 CFR Part 170 rule, the accreditation body, and the credentialed workforce. Items here are usually "who does what" and "which document governs." CMMC is a Department of Defense program, not a NIST publication and not a private certification scheme.
420 words, about 2 min02CMMC Model and Assessment Requirements
This domain tests the model's structure and the mechanics of an assessment: what evidence counts, how requirements are judged, and how results become a certification status. Expect questions on requirement counts, NIST SP 800-171A objectives, scope, and POA&M rules.
458 words, about 2 min03Consulting and Implementation Support for Defense Contractors
This domain tests how an RP supports an organization seeking certification (OSC) without crossing into assessment. You advise, scope, build, and prepare; you do not certify, attest, or affirm for the client.
427 words, about 2 min04Code of Professional Conduct and Ethics
This domain tests judgment. The Cyber AB Code of Professional Conduct binds every credentialed individual and accredited organization, and the exam presents realistic pressure scenarios: a client who wants a favorable result, a schedule that rewards shortcuts, and evidence that is inconvenient.
