Preparing for a CMMC Level 2 assessment begins with understanding the 110 NIST SP 800-171 controls and evaluating your current environment. Start by reviewing your documentation, identifying any gaps, and organizing evidence for each control. Most contractors overcomplicate this step, but the key is to focus on policy alignment, access controls, logging, and staff training.

Before your assessor arrives, make sure you have a structured evidence folder, updated policies, a system security plan, and a clear record of technical implementations. A clean, organized documentation package can significantly reduce assessment time and lead to smoother interviews with the C3PAO team.
