The company officer providing a written or practical test is applying which step in the method of instruction?

The correct answer is evaluation, as this step is crucial for measuring the understanding and performance of learners after instruction has taken place. In this context, when a company officer administers a written or practical test, they are assessing the knowledge and skills that have been taught during the training.

Evaluation helps determine the effectiveness of the instruction and whether the learners have grasped the necessary concepts and procedures. By conducting tests, the company officer can identify areas where students may need further assistance or additional training, and it validates the teaching process by providing feedback on both the learner's and the instructor's performance.

The other options, while related to the instructional process, do not specifically capture what is occurring during the testing phase. Presentation refers to the step where information is delivered to the learners. Application is the phase where learners practice the skills they have been taught. Assessment is a more general term that can encompass evaluation but doesn’t solely refer to the formal testing process. Each of these steps plays a role in the instructional method, but evaluation directly pertains to the testing and measuring of learner outcomes.
