There are various reasons that justify the study of comparative education especially for students of education -teachers in the making (or to-be), practicing teachers, policy makers, education planners and managers and all interested parties.
We study comparative education to discover which reforms are desirable and possible and how best to implement them, and also what successes to borrow and what failures to avoid.
; We study comparative education in order to get exposure to knowledge in other disciplines in humanities and social sciences that also study human affairs so as to enable us have a holistic picture of education.
Education in this regard is considered to be a consumer good.
It therefore must have practical utility for example, ability to read and write.
The task of making education practical is the duty of the government and the educationist.
Comparative Education is therefore considered very suitable for studying this problem.; By studying schools in other countries, comparative education opens the window through which we can understand a society for often the school reflect what the society looks like (schools are the mirrors of society).A school actually reflects or represents the national character.Michael Sadler (1900) said "In studying foreign systems of education, we should not forget that the things outside the school matter even more than the things inside the school and govern and interpret the things inside" vii) Contribute to International understanding and goodwill ; Comparative education fosters international understating, peace and co-operation among nations of the world.By discovering and appreciating what exists elsewhere it replaces national pride and prejudice with the objectivity of judgment that facilitates international harmony.viii) Humanitarian reasons ; The contemporary world is characterized by a big quest for knowledge, peace, equality and better life.
