NIST SP 800-171 Basic Assessment
SPRS score calculator: 110 requirements, one score.
This SPRS score calculator scores all 110 NIST SP 800-171 requirements with the point values of the DoD Assessment Methodology, version 1.2.1: from 110 down to -203, with the points lost by family and the gaps a CMMC POA&M cannot hold. No sign-up; nothing you mark leaves your browser unless you ask for the report.
Mark each requirement
Mark each requirement Met or Not met; 3.5.3 and 3.13.11 also take Partial. Count a requirement as Met when it is implemented, when a plan of action covers a temporary deficiency, when the system security plan describes an enduring exception, or when the DoD CIO approved it as not applicable.
The calculator runs in your browser. Your marks are saved on this device so a reload keeps them, and nothing is sent unless you ask for the report by email.

How the score is computed
The DoD Assessment Methodology starts at 110 and subtracts the value of every requirement not implemented, so a score can fall below zero. These are its rules as the calculator applies them.
- method.start
- Start at 110, one point for each requirement, and subtract the value of each requirement not met. The lowest possible score is -203, when all 313 points are lost.
- method.values
- 5 points where a gap could lead to significant exploitation of the network or exfiltration of CUI, 3 where its effect is specific and confined, 1 where it is limited or indirect. 42 requirements carry 5 points, 14 carry 3, 51 carry 1, and 2 carry 3 or 5.
- method.partial
- Partial credit applies to two requirements only. 3.5.3 loses 3 points instead of 5 when multifactor authentication covers remote and privileged users but not general users. 3.13.11 loses 3 instead of 5 when CUI is encrypted with modules that are not FIPS validated.
- method.plan
- A plan of action does not make a requirement Met: a requirement not implemented loses its points with or without one. A requirement with no plan of action also makes 3.12.2 Not met.
- method.met
- Counted as Met: a temporary deficiency addressed in a plan of action, an enduring exception described in the system security plan, and a requirement the DoD CIO approved as not applicable or as met by an equally effective alternative.
- method.permitted
- Remote access (3.1.12, 3.1.13), wireless access (3.1.16, 3.1.17) and mobile device connection (3.1.18) lose no points when the system does not permit them.
- method.ssp
- 3.12.4, the system security plan, has no value of its own. Without one an assessment cannot be completed, so the calculator shows no score while 3.12.4 is Not met.
What a CMMC POA&M can hold
For the SPRS Basic Assessment, every requirement not yet met needs a plan of action, and it still loses its points. A CMMC Level 2 assessment also limits what a POA&M may hold: under 32 CFR 170.21, a POA&M leads to Conditional status only under the first three rules below, and that status lasts only under the fourth. The calculator marks each gap that can and cannot go on one.
- poam.score
- The score is at least 88, which is 0.8 of 110.
- poam.value
- Every requirement on the POA&M is worth 1 point. The one exception is 3.13.11 marked Partial, encryption used but not FIPS validated, worth 3.
- poam.never
- None of these is on it, whatever its value: 3.1.20 external connections, 3.1.22 public information, 3.10.3 escorting visitors, 3.10.4 physical access logs, 3.10.5 physical access devices, and 3.12.4 the system security plan.
- poam.closeout
- Each item is closed and confirmed by a closeout assessment within 180 days, or the Conditional status expires.
What PolicyCortex does with SPRS
PolicyCortex scores the same 110 requirements with the same values in the product, drafts answers from the evidence it has recorded for a person to confirm, and turns the requirements scored below full credit into POA&M items.

- The ten-question CMMC Level 2 readiness assessment.
- cmmc.checklist
- The 110-control checklist, by control family.
Questions about the SPRS score
- Q-01
How is the SPRS score calculated?
Start at 110 and subtract the value of each NIST SP 800-171 requirement not implemented: 5, 3 or 1 point, as the DoD Assessment Methodology assigns them. Two requirements, 3.5.3 and 3.13.11, can lose 3 points instead of 5. The lowest possible score is -203.
- Q-02
What is the lowest possible SPRS score?
-203: every requirement not met, with a system security plan in place. Without a system security plan, 3.12.4, no score can be produced at all, because the methodology says an assessment cannot be completed.
- Q-03
Does a plan of action raise the score?
No. A requirement not implemented loses its points whether or not a plan of action covers it. The exception is a temporary deficiency that arose after implementation and is addressed in a plan of action, which counts as implemented.
- Q-04
Which requirements cannot go on a CMMC POA&M?
Any requirement worth more than 1 point, except 3.13.11 when encryption is used but not FIPS validated, and 3.1.20, 3.1.22, 3.10.3, 3.10.4, 3.10.5 and 3.12.4 whatever their value. The score must also be at least 88. The rule is 32 CFR 170.21.
- Q-05
Is anything I mark sent to PolicyCortex?
No. The calculator runs in your browser and saves your marks on this device only. If you ask for the report by email, your email address and your marks are sent; PolicyCortex works out the same score from them and emails you the report.
- Q-06
Is this score an assessment of record?
No. It is the methodology's arithmetic applied to your own marks. The score posted in SPRS is the one your organization affirms. PolicyCortex is not an assessor and does not certify anything.
