How to Calculate Your SPRS Score for CMMC Level 2

Calculate your SPRS score Free CMMC compliance tool (SPRS, objectives and POA&M)

Direct answer: an SPRS score for CMMC Level 2 starts at 110 — one point for each of the 110 NIST SP 800-171 Rev. 2 security requirements — and you subtract a weighted 5, 3, or 1 point for every requirement you have not implemented. The weights reflect risk, not effort, so the scale runs from a maximum of 110 down to a minimum of -203. Two requirements allow partial credit (3.5.3 and 3.13.11), and 3.12.4 gates the assessment entirely.

What the SPRS score is

SPRS is the Supplier Performance Risk System. For CMMC Level 2, your SPRS score is a single number representing how completely you have implemented the 110 security requirements in NIST SP 800-171 Rev. 2. You start at a perfect 110 and lose weighted points for every requirement not fully met.

SPRS score range

SPRS scores range from -203 to 110 under the NIST SP 800-171 DoD Assessment Methodology. 110 means every requirement is implemented; -203 means none are.

The 110-point scale and the weighted deductions

It is not one point per requirement. Under the DoD Assessment Methodology, each unimplemented requirement costs 5, 3, or 1 point according to its risk to the confidentiality of CUI, so the scale runs from 110 down to -203. Every requirement is scored all-or-nothing — you earn the point only when every applicable assessment objective is satisfied — with two documented exceptions:

• 3.5.3 (multifactor authentication) carries a 5-point weight. When MFA is implemented for remote and privileged users but not for general users on local access, 3 points are deducted instead of 5.
• 3.13.11 (FIPS-validated cryptography) carries a 5-point weight. When cryptography is employed to protect CUI but the modules are not FIPS-validated, 3 points are deducted instead of 5.

The 3.12.4 gate. Requirement 3.12.4 requires a system security plan. Without one there is no assessment to score, so the calculator treats 3.12.4 as a gate rather than as one more point: mark it Not Met and the result is not a defensible score.

A worked example, verified exactly

Take an organization with 106 of the 110 requirements Met — including 3.12.4, which must be Met for the score to mean anything — and exactly these four exceptions:

Total deductions: 3 + 3 + 3 + 5 = 14. Score: 110 − 14 = 96. Note that you cannot derive this from counts alone: four unimplemented requirements produce a deduction of 14, not 4, because the weights and the two partial-credit rules decide the arithmetic.

Which assessment are we talking about?

Four different things get called "the assessment," and they are not interchangeable:

• SPRS Basic Assessment. Your own self-assessment of the 110 NIST SP 800-171 requirements, scored with the DoD Assessment Methodology and reported in SPRS under DFARS 252.204-7019/7020. This calculator computes that score.
• CMMC Level 2 self-assessment. An assessment against the CMMC Level 2 practices and their assessment objectives, affirmed by a senior official. Related to, but not the same as, the SPRS Basic Assessment score.
• DIBCAC assessment. A government-conducted assessment by the Defense Industrial Base Cybersecurity Assessment Center. Not something you self-report.
• C3PAO assessment. A CMMC Level 2 certification assessment conducted by an authorized third-party assessment organization. Only a C3PAO (through the accreditation body) can produce a CMMC certification.

Nothing on this page produces a certification, an official score, or a submitted SPRS entry. It is a readiness aid.

How to calculate it, step by step

1. Confirm your scope. Identify the assets that store, process, or transmit CUI. Scoping errors are the most common reason a score has to be redone — the CUI scoping check walks the categories.
2. Assess all 110 requirements against their assessment objectives with the Level 2 self-assessment checklist. A requirement is Met only when every applicable objective is satisfied.
3. Prove each objective with the artifacts an assessor will examine — the 320-objective evidence checklist lists them.
4. Apply the weighted deductions (5/3/1) and the two partial-credit rules, then subtract from 110.
5. Build your POA&M for the gaps with the POA&M builder — not every requirement is eligible.
6. Submit in SPRS with your assessment date and scope, then use the C3PAO preparation checklist before a certification assessment.

One caution: submitted scores are spot-checked against system security plans. A number you cannot defend with evidence is a liability, not an asset.

Turning the number into something defensible

Hand-scoring 110 weighted requirements is the easy part. The hard part is the evidence behind each of the 320 assessment objectives, and the POA&M that closes the gaps in an order an assessor will accept. That is what Athena does with the score you just produced.

FAQ

What is a passing SPRS score?

110 means every requirement is met; 88 or above with a valid POA&M supports Conditional status; below 88 is no CMMC status.

What is the lowest possible score?

-203 — because unimplemented requirements carry weighted 3- and 5-point deductions.

Can every requirement be placed on a POA&M?

No — higher-weighted practices are not eligible, a minimum score is required to use one, and scoring is all-or-nothing apart from 3.5.3 and 3.13.11.
