NASA's Compliance with Executive Order 13526: Classified National Security Information
"However, while the Agency's procedures meet Federal requirements, its implementing directive does not require Agency personnel with classification authority to receive all necessary training. Additionally, we found instances in which Agency personnel were not consistently following these NASA policies. Specifically, we found classified documents that were improperly marked,training requirements that were not met, and self-inspections that were not fully implemented. Although these deficiencies were relatively minor in nature, failure to comply with these requirements increases the risk that personnel may inadvertently misclassify material."
