The Certification Study Guide (6th edition) emphasizes that educational objectives must be written using measurable, observable action verbs that clearly define learner outcomes. This principle is grounded in adult learning theory and Bloom’s taxonomy, both of which are highlighted in the education and communication sections of the guide. Effective objectives allow educators to evaluate whether learning has occurred by observing or assessing learner performance.

The verb “know” is considered inappropriate because it is vague and not measurable. It does not specify how the learner will demonstrate knowledge, making it impossible to objectively assess whether the objective has been achieved. For this reason, “know” is frequently cited in the study guide as an example of a poorly written objective verb.

In contrast, verbs such as define, compare, and explain are acceptable because they describe specific actions the learner can perform. These verbs allow the instructor to evaluate learning through verbal responses, written assessments, or demonstrations. The study guide stresses that well-written objectives should answer the question: What will the learner be able to do at the end of the session?

This concept is commonly tested on the CIC exam because infection preventionists are expected to design and deliver education effectively. Clear, measurable objectives support competency-based education, documentation of learning outcomes, and program evaluation—all essential components of a successful infection prevention program.
