How it's scored
5 points deducted from your SPRS score if unmet.
An open gap here is not POA&M-eligible (only 1-point requirements qualify under 32 CFR 170.21, with one narrow exception at SC.L2-3.13.11): it must be fully implemented before a Level 2 assessment can certify.
What an assessor checks: the 6 assessment objectives
NIST SP 800-171A determination statements, verbatim. A CMMC Level 2 assessor marks SC.L2-3.13.2 MET only when every applicable objective is satisfied — and examines evidence, not assertions.

| 3.13.2[b] | software development techniques that promote effective information security are identified. |
