Assessment objectives

Assessors don’t evaluate the requirement as one sentence; they walk these objectives one by one. Each must be met for the requirement to score.

  1. 3.8.4[a]media containing CUI is marked with applicable CUI markings.
  2. 3.8.4[b]media containing CUI is marked with distribution limitations.

Inside Valontir, this requirement carries a full plain-English guide: what it asks in normal words, what good looks like in a small shop, the evidence an assessor accepts, the common gaps that cost points, and a plain reading of every assessment objective shown above. See it in a demo.
