The job duties and responsibilities of teaching remain the same whether you work in a public school or a private school. However, there are key differences for teachers in public versus private school environments. For instance, public schools are legally bound to admit all students, regardless of demographics, academic achievement, or behavioral issues. Private schools can be more selective when admitting students. In public schools, government legislation often dictates curriculum and learning standards. This is not the case in private schools. Private schools also have more flexibility when it comes to hiring teachers.
