Teacher vs Professor
Teacher and Professor are two professions that are sometimes interchanged, though there is some difference between them. A teacher is one who teaches various subjects in a school. On the other hand, a professor teaches at a college or in a university. This is the main difference between teacher and professor.
A teacher in a school is qualified with or without a research degree. On the other hand, he gets an appointment as a professor in a college only if he has a research degree to his credit. Otherwise, he is not eligible to apply for the post of lecturer or a professor in a college.
On the other hand, any person who has worked as a teacher in a school is eligible to earn a research degree studying part time and become a professor in a college. On the other hand, a professor that has retired from a college or a university can work in a school too, if he desires.
Sometimes, the word professor refers to a lecturer who teaches at the university only. Any educator who teaches at a college is called by the name lecturer. Sometimes, the head of the department in a college alone is called a professor. All other educators who teach in the department are called as lecturers only. On the other hand, any person who teaches at school is called a teacher.
A school teacher is either a trained graduate teacher or a post graduate teacher. A trained graduate teacher is called as a TGT, whereas a post graduate teacher is called as PGT. The salary drawn by a professor is higher than the salary drawn by a teacher in a school. These are the major differences between the two important words that are often confused, namely teacher and professor.
