For many organizations in the DIB, the phrase CMMC self-assessment creates more questions than answers.
Where do we begin? Does every contractor have to complete one? What information must be submitted?
It can be complicated, and the answers depend on the type of information your organization handles and the requirements included in your contracts.
Below is a guide we've put together to help explain the self-assessment process, the risks, and how to make sure your organization is prepared.
What Is a CMMC Self-Assessment?
A CMMC self-assessment is an internal evaluation of how well your organization meets the cybersecurity requirements associated with your required CMMC level. Rather than having an outside assessor evaluate your environment, your own personnel review each required practice, collect evidence, identify deficiencies, and document the results.
The goal isn't simply checking boxes, and the risks are real.
A quality self-assessment helps determine whether your security controls are operating effectively and whether your organization is prepared to satisfy contractual cybersecurity obligations.
For organizations that only require a self-assessment, this process becomes part of their ongoing cybersecurity program rather than a one-time event.
Which Organizations Can Self-Assess?
Not every defense contractor is eligible for a CMMC self-assessment.
Eligibility depends on the CMMC level required by the contract and the sensitivity of the information being protected.
Generally:
- Organizations requiring CMMC Level 1 complete an annual self-assessment.
- Some Level 2 contractors may also perform an annual self-assessment when specified by the applicable contract.
The Self-Assessment Process
Although every organization operates differently, most successful self-assessments follow a similar sequence.
1. Understand Your Assessment Scope
Before reviewing security controls, determine exactly what systems, users, locations, cloud services, and data fall within scope.
One of the most common reasons organizations struggle during assessments is unclear scope. Defining your CMMC boundary early makes the remainder of the process more manageable.
2. Review Each Required Practice
Once scope is established, evaluate every required practice for your CMMC level.
This means confirming that policies exist, procedures are documented, technical safeguards are configured correctly, and employees consistently follow these processes.
The assessment should focus on both documentation and operational implementation.
3. Gather Supporting Evidence
Evidence demonstrates that security practices are actually being performed. Collecting evidence throughout the year is far easier than attempting to recreate it shortly before an assessment.
Examples include:
- Policies and procedures
- Configuration settings
- Multi-factor authentication screenshots
- Asset inventories
- Vulnerability scan reports
- Audit logs
- Security awareness training records
- Incident response documentation
- Backup verification reports
A lack of evidence indicates that the processes are not fully or consistently implemented.
4. Address Gaps
Few organizations complete an assessment without identifying opportunities for improvement.
Commonly, it is missing documentation, incomplete processes, outdated configurations, or inconsistent implementation. These should all be corrected before the next assessment cycle.
Treat the assessment as an opportunity to strengthen your cybersecurity program rather than simply measuring compliance.
Understanding SPRS Reporting
SPRS records the organization's assessment score and demonstrates compliance with DoW cybersecurity reporting requirements. Organizations will need to upload their scores to SPRS at the end of their self-assessment.
Maintaining current assessment information ensures contractors remain eligible for future opportunities requiring NIST SP 800-171 or CMMC compliance.
Make Self-Assessments Easier
The organizations that experience the least stress during assessments typically don't prepare once a year, they prepare continuously.
Some best practices include:
- Review cybersecurity controls throughout the year.
- Keep documentation current after system changes.
- Maintain organized evidence repositories.
- Perform periodic internal reviews instead of annual catch-up exercises.
- Update inventories as assets are added or removed.
- Validate backups, incident response procedures, and access controls regularly.
Continuous compliance usually requires less effort than scrambling before deadlines.

If you're unsure where to begin, let's talk through it.
Identifying issues before they become contractual problems is one of the most effective ways to reduce risk and stay competitive in the defense marketplace.
