Which of the following is NOT considered a tool in social work?

In social work, tools are essential for effectively assessing and assisting clients. An interview is a fundamental method used to gather information, build rapport, and understand a client's situation. Effective communication is crucial for conveying empathy, understanding client needs, and facilitating change. An ecological map serves as a visual representation of a client's environment, highlighting relationships, support systems, and other factors that may influence their well-being, thus aiding in planning interventions.

Thermal imaging, however, is not a recognized tool within the context of social work. It is primarily a technology used in certain fields such as medicine and engineering, primarily for detecting heat patterns rather than for assessing social or emotional needs. This distinction underscores why thermal imaging is not part of the toolkit used by social workers in their practice.
