• Since the Instructor has to teach the prescribed course, if in case there is no planning he cannot teach the entire course content in time. It is therefore necessary to plan a lesson.

• The Instructor has to achieve some definite results by teaching. If a lesson is taught according to lesson planning, then only the teacher can teach well.

• Teaching in an improper manner will not bring the desired results. If no aim is fixed, it will be useless to teach a lesson.

• When a teacher/trainer is prepared to teach a lesson, he enters the class with some definite aim.

• He/she is self confident that he/she will teach a lesson well then he/she need not depend on his/her memory.

• He is also prepared to face the learners and answer their probable questions.

• He/she is able to solve any problem regarding the lesson to be taught.

• He/she finishes the lesson according to the plan in the prescribed time and schedule.

• It is therefore very much necessary to plan a lesson. In this way, then much teaching can be done in time.
