How to use your SPRS Score Calculator.
The workbook has three sheets. Here's the fastest path from download to knowing your score.
Open the 📋 Assessment sheet
This is your working sheet. All 110 NIST 800-171 controls are listed with their penalty point values and the full requirement text. Everything you need to complete your self-assessment is on this sheet.
Select a status for each control using column F
Click the dropdown in column F for each control and select
Met
,
Partially Met
,
Unmet
, or
Not Assessed
. The score impact in column H updates automatically. Work through all 110 controls before submitting your score to DoD.
Add notes in column I for any N/A or Partially Met controls
The Notes column is where you record your implementation evidence, not-applicable justifications, and remediation plans. This documentation is what a C3PAO assessor will look for. Don't skip it — especially for controls you've marked Met but with an N/A rationale.
Check your running score on the 📊 Dashboard
Your SPRS score updates in real time as you mark controls. The Dashboard shows your total score, a status count summary, and a family-level breakdown — so you can see which of the 14 control families is driving the most score risk.
Submit your score to SPRS
When your assessment is complete, self-report your score at sprs.csd.disa.mil. You'll need a CAC card or ECA certificate and your organization's CAGE code. The score you enter there should match the score in your completed calculator.
