Since there is little scope for professional growth for teachers in schools and colleges, many people take up a teaching job as the last resort. So the quality of education is poor with limited job prospects. To overcome this problem, students flock to private training institutes.
Since the main aim of these training institutes is making a profit, they try to ensure that the subjects taught to the students are in demand. They also try to ensure placement for their students, so that they can list it in their promotional literature.
