Requirement ID: IVV-CSO-FIA
The requirement
The official language varies by certification class. Each class statement is quoted exactly below.
Class A (force: MAY): “Providers with Class A Certifications MAY persistently complete an independent verification and validation assessment of all applicable FedRAMP rules with a FedRAMP Recognized independent assessment service OR FedRAMP at least once per year; this is a FedRAMP independent assessment.”
Class B (force: MUST): “Providers with Class B Certifications MUST persistently complete an independent verification and validation assessment of all applicable FedRAMP rules with a FedRAMP Recognized independent assessment service OR FedRAMP at least once per year; this is a FedRAMP independent assessment.”
Class C (force: MUST): “Providers with Class C Certifications MUST persistently complete an independent verification and validation assessment of all applicable FedRAMP rules with a FedRAMP Recognized independent assessment service OR FedRAMP at least once per year; this is a FedRAMP independent assessment.”
Class D (force: MUST): “Providers with Class D Certifications MUST persistently complete an independent verification and validation assessment of all applicable FedRAMP rules with a FedRAMP Recognized independent assessment service OR FedRAMP at least once per year; this is a FedRAMP independent assessment.”
What does this mean?
An outside party checks your security work rather than relying only on your own internal review. That outside party is either a FedRAMP Recognized independent assessment service or FedRAMP itself.
The assessment looks at all applicable FedRAMP rules for your cloud service offering and confirms, through objective evidence, both that the specified practices were fulfilled (verification) and that the results are suitable for their intended use (validation).
The cadence is at least once per year, and it is meant to run steadily over time rather than as a one-off. For Class A the activity is optional (MAY). For Classes B, C, and D it is mandatory (MUST).

Why does this matter?
Self-assessment alone can miss gaps because the people who build and run a system may not see their own blind spots. An independent review provides assurance to federal customers that the security posture is real, current, and backed by evidence.
If the annual independent assessment is skipped or lapses, the certification behind the offering can lose its foundation. Findings that would have surfaced may go undetected, and federal customers lose a trusted, repeatable signal that the offering still meets FedRAMP practices.
What could implementation look like?
This is illustrative, not mandatory. One approach is to treat the independent assessment as a recurring annual program rather than a single event.
A provider could maintain a calendar that schedules the assessment before the prior one expires, select a FedRAMP Recognized assessment service (or engage FedRAMP where applicable), and keep the scope aligned to all applicable FedRAMP rules for the offering. Because the requirement uses the word “persistently,” documenting the cycle, any waiting periods, and the current status could help demonstrate the activity is intentional and always known.
Example scenario
A mid-sized cloud provider holds a Class C certification for its data analytics platform. Each year, roughly two months before the prior assessment result reaches its anniversary, the compliance team engages a FedRAMP Recognized assessment service.
The assessor reviews evidence across all applicable rules, tests a sample of controls, and issues an assessment report. Because the provider maintains an on-demand trust center, most of the implementation and effectiveness evidence the assessor needs is already current and accessible rather than assembled fresh for the engagement. The provider tracks the engagement start date, assessment window, and completion in a shared register so leadership can see the status at any time. When one cycle closes, the next is already scheduled.
What evidence could demonstrate implementation?
Examples may include:
- Signed engagement records or contracts with a FedRAMP Recognized assessment service
- The completed independent assessment report covering applicable FedRAMP rules
- A schedule or register showing the annual cadence and current status
- Records of scope decisions confirming coverage of all applicable rules
- An on-demand trust center or similar continuous evidence portal giving the assessor direct access to implementation and effectiveness evidence, rather than a one-time document handoff at assessment time
Common pitfall
Treating the assessment as a project that happens once and then goes dormant. The word “persistently” points to a steady, repeated cycle with known status. Letting the timing drift past the annual mark, or narrowing scope so it no longer covers all applicable rules, can undermine the assurance the assessment is meant to provide.
Question for your team
Do we have a documented, always-current view of when our next independent assessment starts and ends, and does its scope clearly cover all applicable FedRAMP rules for our offering?
Key takeaway
An outside, FedRAMP Recognized assessment of all applicable rules, run on a steady yearly cycle with known status, is what keeps independent assurance behind the offering credible and continuous.
