A good objective specifies the behavior that trainees should exhibit following instruction. Two words to remember when specifying behavior are " For an objective " and " measurable ". For an objective to be observable and measurable, it must describe what action you expect to see. Thus. objectives must include action verbs. For example, if the objective states that trainees must disassemble a carburetor, you should be able to observe the dis assembly and measure whether it was dis assembled correctly.
