Because school-based research is "for the school, in the school, based on the school." As the first responsible person, the principal must proceed from the actual situation of the school and make decisions around school-based research. The decision-making should be appropriate and clear, and it should be recognized by all teachers, which is the basic condition to ensure the implementation of school-based research and judgment.

First of all, the decision should be appropriate. Suitability comes from the orientation of teachers, from the development requirements of schools, and from a series of problems faced by schools. Scientific research activities in primary and secondary schools should proceed from reality, not take so-called innovation as the only measure, not take long academic papers as an important form of expression, and teachers should form their own personalized achievements. This requires the headmaster to put forward appropriate school-based decisions from the requirements of school development and the problems faced by teachers.
