If this approach is used, students will learn and retain at a better rate. Content should be consistent. After developing class content, the instructor should present the same information to each class taught. As students ask questions, training materials should be updated. If multiple instructors teach the same class, consistent materials will assure that each student receives the same information.
Techniques are unique to each instructor.
Quality trainers are those who have developed their own style of training. Audio-visual equipment varies with classes and instructor participation. Whatever the techniques may be, instructors should evaluate their effectiveness and be ready to redesign classes when the techniques don't work or need to be updated. Success measurements are crucial. Trainers benefit from classroom evaluations.
