From 65438 to 0957, Professor Hans Heckel of the Law Department of the German University of International Education and Professor Sipp co-authored the School Law, which systematically expounded the legal composition of the school system, the legal relationship between management and education, and was regarded as the earliest monograph on education law in the world.

In the United States, the School Law-A Teacher's Manual, co-authored by Nolte and Lynn, is the first systematic work on education law.
