1. Teachers in public sectors are not well trained just like private sectors because the policies are bogus for the training of educators. People who do not get job in any other sectors try to find jobs in education system which is very bad for students. They are not professionally trained and cannot educate the children. The specialized people are very rare in government sectors which is cause of failure of education system. We can say that any nation cannot progress without hiring the trained teachers.
