First, fully take care of students' development differences and be able to teach students in accordance with their aptitude.

Second, it eliminates intellectual discrimination and is easily accepted by students.

Thirdly, the competition mechanism in hierarchical teaching enables students to accept challenges and achieve leaps and bounds in the process of continuous circulation, thus easily forming a lively, mutual help and catching up with each other, forming a multi-directional interactive classroom teaching situation, reducing students' research burden and improving students' research results.

Hierarchical teaching means that teachers scientifically divide students into several groups with similar levels and treat them differently according to their existing knowledge, ability level and potential tendency. These groups get the best development and improvement through teachers' appropriate stratification strategies and interactions.

Hierarchical model of directional training objectives

This model is mostly limited to vocational education. Refers to the teaching in different levels and classes according to the graduation direction of students. The specific method is to conduct a thorough investigation when entering school to understand the students' knowledge and ability level, as well as their choices for employment and further studies. While respecting the opinions of students and parents, we also give feedback on our own learning situation and make a correct positioning.

Then according to the students' foundation and development, it is divided into two levels, namely, the further education class and the employment class. The main cultural courses in the two classes have the same teaching materials and the same progress, but the teaching objectives and the difficulty of knowledge are different. Admission classes pay more attention to the cultivation of test-taking ability, while employment classes emphasize the combination of cultural knowledge and professional practice.

When grade two students pass the proficiency test, the school provides them with a second choice. Continuing education classes further strengthen cultural courses and major professional courses, and employment classes focus on vocational skills training.
