In my opinion, I think there are 3 qualities that a teacher must have in order to be great.

**Knowledge**

You can't teach what you do not know. Hence, knowledge is an important quality for any teacher.

**Empathy**

Knowing your stuff doesn't mean you know how to impart your knowledge. And that's why I think empathy plays an important role. Good teachers follow a curriculum and stick by the books. Great teachers understand every student and tailor their teaching style to suit each student. In order to do this, you need to understand how each student feel. Learn about their problems and difficulties. This requires a lot of empathy.

**Growth mindset**

Learning is a never-ending journey. This is something which I think great teachers will all agree. And in order to keep learning, you need to have growth mindset. The key thing here is to teach students how to learn on their own and encourage them to keep learning. Great teachers with a growth mindset will be able to lead by example and become the inspiration for students.
