Which of the following is NOT a phase of security education?

The correct answer is Sensitive Compartmented Information, as it does not represent a phase of security education. The phases of security education typically involve initial training, where foundational knowledge and practices are established, ongoing training to keep personnel updated on security protocols and evolving threats, and assessments that evaluate the effectiveness of the training and understanding of security measures.

Sensitive Compartmented Information is a classification of data, which refers to information that requires special protection due to its sensitive nature. This classification is related to the handling and dissemination of information rather than being a step or phase in the training process itself. Consequently, while it’s an important aspect of security and operational protocols, it does not constitute a phase of education aimed at enhancing personnel’s security awareness and capabilities.
