Hello Rajat,

There are many ways to become a teacher in high and intermediate level. The teachers for high school are in a high demand and the number of jobs are increasing as a bunch of  new schools are being constructed every year.

To become a high school teacher, you need to have a bachelor's degree and could probably have teacher certification so as to have an experience of teaching. To a higher qualification, master's degree and then PG is required. 

To become a lecturer in intermediate colleges,you need to posses bachelor's degree, master's degree and then PG courses.You can even complete your PhD.

If you can complete your PhD, you can become a professor in engineering colleges which is a respectable position.You can even become the head of some department in your college too.

Hoping for the best,All the Best!!
