Duties of Coach in Tennis are : 

1. Learn how each student learns best : Some students are visual learners, since they emulate what they see. Other students are auditory learners who understand by listening. Some are kinesthetic learners, in that they need to perform a movement to understand it best. Make an assessment of the students’ learning style and adjust the message accordingly. 

2. Separate the performance from the performer : One of the most important things coaches can do is build every player’s selfesteem, no matter what their skill level is Make sure every comment is constructive, sandwiched between compliments and correction. 

3. Be demanding and disciplined, never demeaning : The coaches style must be based on the laws of learning. If screaming, yelling, or putting down a player was the best way to teach, then all teachers in school classrooms would be using that method. Coaches must make sure they are teaching, not taking out their frustrations or setting unrealistic expectations. Coaches should never be demeaning to their athletes. 

4. Coach smarter, not harder : Experience is a great teacher, but attending coaching clinics and learning from other coaches is essential. Sharing and bouncing ideas off other coaches will lead to greater coaching wisdom. 

5. Be innovative, not imitative : This is hard to do, but it’s best to not just copy other successful coaches. For instance, don’t just copy practice plans. 

6. Put the needs of the player first : The experience of coaching is first and foremost about providing a secure, productive, healthy and motivating environment for players to learn, develop and grow. It is not about satisfying the coaches or parents’ needs. Do not exploit your players. 

7. Be a role model : A coach should emphasise the importance of hard work, perseverance attentiveness, determination health and fitness. The greatest impact however, is when coach personally embody and repeatedly display these attributes. “Do as I say” is not as powerful a message as “Do as I do!”
