Which of these represents an indirect supervision activity?

Indirect supervision activities are those that do not involve real-time observation of a session but rather take place outside of the direct interaction with clients. The option concerning the review of progress in a professional development plan exemplifies this concept effectively. This activity involves evaluating personal growth, identifying areas for improvement, and understanding the application of learned skills, all indirectly related to the direct service being provided to clients.

In contrast, role-playing scenarios and directly observing a session involve direct interaction or observation, making them direct supervision activities. Discussing ethical considerations can also encompass both indirect and direct elements, but it typically isn't categorized solely as indirect since it can be part of immediate training or support during practice. Therefore, reviewing professional development progress remains the clearest example of an indirect supervision activity, as it focuses on self-assessment and planning rather than direct client interaction.
