First of all, (including two confusing concepts):

1, the purpose and policy of education:

Education policy is the macro guiding ideology and general education direction of education. The structure of education policy includes three parts: the nature and direction of education, the purpose of education and the basic ways and principles to realize the purpose of education.

2, the purpose of education and training objectives:

The purpose of education is the general requirement of the state for all kinds of schools at all levels, while the training goal is the specific requirement for a certain level or type of school or a certain specialty according to the purpose of education. The two are general and individual, universal and special; Secondly, the formulation of training objectives must conform to the educational objectives, which must be reflected and implemented through the training objectives of schools and majors at all levels.

Second, the purpose of education is the general policy followed by all kinds of schools at all levels, but all kinds of schools at all levels also have their own specific work policies and training objectives, which determines that the purpose of education is hierarchical. This level includes:

The purpose of education-country

Training objectives-schools

Course objectives-discipline

Teaching objectives (semester, unit, class hours)-classroom

I wonder if you are preparing for the teacher's exam. I suggest that you choose a textbook that is analytical, comprehensible and practical, which is easy to remember and understand. Good luck!
