Written tests are a method to evaluate:

Written tests are specifically designed to evaluate knowledge change, as they assess an individual's understanding of specific concepts, facts, and information that have been taught or presented. When a written test is administered, it measures what a person knows at a given moment, based on the material they have been exposed to.

In the context of fire and life safety education, a written test can gauge how well participants have grasped essential safety protocols, regulations, or procedures, indicating a shift in their knowledge as a result of the educational program. This method provides tangible evidence of the learning that has occurred, allowing educators to determine areas of success or aspects that may need further attention.

Other options do not primarily focus on knowledge change. For example, behavior change relates to how individuals may alter their actions based on their knowledge, which typically involves a more complex process beyond just testing. Subjective learning pertains to personal interpretations of experiences and may not be measurable through formal testing. Environmental change usually refers to modifications in the surroundings that affect safety and does not relate directly to evaluating individual knowledge.
