In 1989, the course of study (primary and secondary school in Japan) was reformed, and the change of curriculum choice was extended in junior high school. But, we have many problems with this system. In the school history since 1949, we estimate the system of curriculum choice have been obliged to bear the function of educational selection. Therefore, we have the conclusion that if the principle and conditions of curriculum were not changed for the better, we can't expect the system to succeed. (1) We must change the principle of education from the selection to the choice. (2) Conditions of education must be reformed. (3) Autonomy by pupils must be valued in the process of choice. (4) Evaluation system must be established. (5) In the school, all teachers need to come to an agreement about the curriculum.
