Cyber AB CCA Certification Guide 2025: Requirements, Exam Details & How to Get Certified

If you want to help defense contractors earn their CMMC Level 2 certification, the Cyber AB CCA certification is your official pathway into accredited assessment teams. In this comprehensive 2025 guide, you’ll learn what the CCA is, who it’s for, how to qualify, how the exam works, how to prepare, what it costs, and how to get hired.

By the end, you will know exactly how to go from “interested” to “in demand” as a Certified CMMC Assessor in 2025–2028.

What Is the Cyber AB CCA—and Why It Matters Now

The Certified CMMC Assessor (CCA) is Cyber AB’s Level 2 assessor credential. CCAs serve on teams within a C3PAO (Certified Third-Party Assessor Organization) to perform official CMMC Level 2 certification assessments for defense contractors (OSCs).

A CCA must be able to:

• Apply DoD’s Level 2 Assessment Guide

• Use NIST SP 800-171A assessment methods

• Evaluate documentation, evidence, and interviews

• Produce defensible assessment findings

In plain terms, CCAs turn CMMC requirements into validated certification decisions.

Why CCA Is Becoming Critical (2025–2028)

The DoD finalized the DFARS rule on September 10, 2025, making CMMC enforceable starting November 10, 2025. The rollout phases (2025–2028) mean thousands of contractors will require Level 2 certification.

Demand for qualified CCAs is about to surge, especially between 2026–2028, when enforcement peaks.

Actionable takeaway:
If you already work in audits or cybersecurity, CCA is your fastest path to high-value CMMC assessment work in the coming years.

Who Should Pursue CCA (And Who Shouldn’t)

CCA is ideal for professionals who:

• Have 3+ years of cybersecurity experience

• Have 1+ year of assessment or audit experience (ISO 27001, SOC 2, FedRAMP, internal audit)

• Are comfortable reviewing evidence, conducting interviews, and documenting findings

• Want to perform official CMMC Level 2 assessments as part of a C3PAO

CCA might NOT be the right first step if:

• You’re new to cybersecurity or compliance

• You don’t yet understand scoping, auditing, or evidence-based evaluations

• You have not completed CCP, the required precursor certification

If you’re early in your career, start with the CCP (Certified CMMC Professional).

Actionable takeaway:
If you lack real audit experience, do CCP first and shadow internal assessments to build credibility.

CCA Prerequisites & Eligibility (Clear List)

To sit for the CCA exam, you must meet all of the following:

• ✔️ Active CCP certification

• ✔️ CCA training from a CAICO Approved Training Provider (ATP)

• ✔️ U.S. citizenship

• ✔️ Favorable Tier 3 (or equivalent) determination / NAC

• ✔️ 3+ years cybersecurity experience

• ✔️ 1+ year audit/assessment experience

• ✔️ One baseline cert mapped to DoDM 8140.3 Work Role 612 (Security Control Assessor), such as:

  • CompTIA Security+

  • ISC2 CGRC/CAP

  • CySA+

  • CISA

  • CISSP

  • CISM

  • GIAC GSEC/GSLC/GSNA

Baseline certification timing is important—don’t leave it until the last minute.

Actionable takeaway:
If you’re missing your baseline cert, schedule it immediately—these take 4–8 weeks to prepare.

The CCA Exam: Format, Domains & Scoring

Exam Details

• Delivery: Meazure Learning

• Format: 150 MCQs

• Duration: 4 hours

• Type: Closed book

• Passing Score: Scaled 500+

• Results: Immediate

• Retake Policy: One paid retake before retraining is required

CCA Exam Blueprint (v3.3)

What Mastery Looks Like

You need to be able to:

• Scope systems correctly across CUI assets, security protection assets, etc.

• Apply examine / interview / test from NIST SP 800-171A

• Follow the CAP lifecycle for planning, assessing, reporting, and closure

Actionable takeaway:
Print the blueprint and create a “master annotation copy” to guide your entire study plan.

DoD Rule Timeline (What CCAs Need to Know)

• Final rule published: September 10, 2025

• Rule effective: November 10, 2025

• Phase 1 begins: November 10, 2025

• Scale-up (certification volume spike): 2026–2028

Over the next three years, Level 2 assessments will gradually be required in more solicitations—driving strong demand for qualified assessors.

Actionable takeaway:
If you want paid assessment work in mid-2026, complete CCA by mid-year to join first-wave teams.

What CCAs Actually Do (Day-to-Day Assessment Work)

You will work with:

• DoD’s Level 2 Assessment Guide

• DoD Scoping Guidance

• NIST SP 800-171A

• Cyber AB’s CAP

Operational Responsibilities

• Validate evidence sufficiency (documents + interviews + tests)

• Conduct interviews with SMEs to confirm implementation

• Validate practices using 171A methods

• Write defensible findings aligned to CAP

• Ensure independence (no conflict of interest with clients)

Evidence Hashing Requirements

For Level 2 certifications:

• OSCs must hash all assessment artifacts

• Hashing must use NIST-approved algorithms

• Evidence must be retained for six years

• CCAs verify and upload the hash list into CMMC eMASS

Actionable takeaway:
Create your own internal "evidence sufficiency rubric"—it dramatically improves consistency across assessments.

Key Skills CCAs Need (and Pitfalls to Avoid)

Essential Skills

• Scoping mastery

• 171A methods discipline

• Clear writing & justification skills

• Interview planning & execution

Common Mistakes to Avoid

• Asking poorly structured or vague evidence requests

• Relying only on documentation without testing

• Missing independence requirements

• Weak rationales that don’t align with CAP expectations

Actionable takeaway:
For each 800-171 practice, write two interview questions and two test steps. This is exam prep and real assessment practice.

CCA Study Plan: A Step-by-Step Roadmap

Phase 1 – Foundation (1–2 weeks)

• Read the CCA Exam Blueprint

• Read the Level 2 Scoping & Assessment Guides

• Skim NIST SP 800-171A

• Skim the CAP

Phase 2 – Practice (2–3 weeks)

• Conduct scoping drills

• Build an evidence playbook for all 110 practices

• Practice examine/interview/test application

Phase 3 – Exam Readiness (1–2 weeks)

• Take timed practice exams

• Rehearse CAP-aligned documentation

• Validate your weak areas against the blueprint

Actionable takeaway:
Schedule your exam near the end of Phase 2—commitment increases discipline and success rate.

Costs & Budgeting for the CCA Path

Cyber AB / CAICO Fees

• CCA Registration: $50

• CCA Exam: $350

• Annual Renewal: $500

• CCP Prereq Fees:

  • CPN: $200

  • CCP exam: $275

  • CCP annual renewal: $250 (until earning CCA)

Training

CCA training typically costs $1,695–$3,500 depending on the ATP provider.

Baseline Certifications

Varies by vendor (CompTIA, ISC2, ISACA, GIAC, etc.).

Time Investment

Most candidates need 4–8 weeks after training to fully prepare.

Actionable takeaway:
Budget for training, one retake, and one baseline certification—don’t rely on best-case timing.

Career Value & Job Market Outlook

Why demand is exploding

• DoD enforcement begins in 2025

• Level 2 certification volume spikes through 2028

• C3PAOs must hire and retain CCAs to stay authorized

Salary Signals (Based on Public Job Postings)

CCAs often command:

• $130K–$200K+ depending on:

  • Clearance

  • Travel requirements

  • Leadership responsibilities

  • Employer (C3PAO vs consulting firm)

C3PAO Staffing Requirements

Each authorized C3PAO must associate at least:

• 1 Lead CCA (LCCA)

• 1 CCA

• A QA function staffed by a CCA

Actionable takeaway:
If you want to become a Lead CCA, start developing reporting, QA, and leadership skills now.

CCA vs CCP: Which One Should You Take First?

• CCP = Foundational certification

• CCA = Level 2 assessor certification

You must:

• Hold CCP

• Complete ATP CCA training

If you’re new to CMMC, complete CCP first, then do CCA within 3–6 months.

If you’re already an assessor or auditor, go straight into CCA training after meeting prerequisites.

Where CCA Fits in the Contractor Lifecycle

A typical OSC Level 2 journey:

1. Readiness & gap remediation

2. Annual self-assessments

3. C3PAO certification (where CCAs perform the assessment)

4. POA&M close-out

5. Certificate maintenance (3-year cycle)

Actionable takeaway:
Understanding this lifecycle boosts your value as an assessor—it's not just about assessment day.

Tools, Templates & Operating Tips for CCAs

Build your personal toolkit:

• Scoping kit: asset inventory templates, decision trees

• Evidence toolkit: method-mapped request lists, interview plans

• Test procedure checklists

• CAP-aligned reporting templates

• Evidence hashing checklist

Actionable takeaway:
Convert your study notes into reusable templates. They compound your efficiency over multiple engagements.
