The school broke the traditional teaching procedure, boldly introduced advanced teaching modes such as Jianping mode, foreign thinking experience, Dulangkou experience and differential teaching, and formed a characteristic education mode combining brand-new education mode with Chuxiong localization education mode. In the teaching practice, the school carries out the far-reaching teaching concept of "giving full play to talents" and "teaching students in accordance with their aptitude", and offers characteristic and forward-looking education classes such as inspirational classes, parallel culture classes, art classes and physical education classes. According to the characteristics of students in Chuxiong Economic Yi Autonomous Prefecture, the school has been teaching according to the syllabus and college entrance examination indicators, and has achieved great success in just a few years since its establishment. In the high school class system, Rentian Middle School divides classes into four types according to the different needs of students, so that different students can get the development they need in different aspects. The correctness of the unique class system has been proved by the results of previous college entrance examinations.

Inspirational class: composed of students from poor families with excellent grades. Class members are free of tuition and books, and the monthly subsidy is 150-400 yuan (provided by the government, Chongqing Chengsheng Group and social charity). And each student who gets a key score in the college entrance examination will be given a scholarship of 15000 yuan (provided by Chuxiong Development Zone Management Committee, Chongqing Chengsheng Group and Principal Scholarship).

Physical education class and art class: They are composed of students with excellent achievements in physical education and art. The students in the class develop their specialties according to their own conditions, implement the idea of preparing for the exam with the common development of culture and professional art, and ensure that the comprehensive online rate of art and physical education candidates is above 98%.

Parallel culture class: that is, the ordinary high school placement system, the first year of high school is not divided into classes, and the second year of high school is divided into subjects according to students' interests and actual conditions. The school also holds excellent training courses and make-up classes for students with good and poor grades in mathematics, foreign languages and physics and chemistry to ensure students' all-round and high-quality development.
