Nanjing Shuren School divides its classes based on academic performance and potential. The school employs a tracking system that segregates students into different academic streams, such as science, arts, and humanities. This system is designed to cater to the diverse interests and abilities of students, ensuring that they receive an education tailored to their strengths and career aspirations.

The rationale behind this class division is rooted in the belief that students benefit from an educational environment that matches their academic abilities and interests. According to a study by the Nanjing Shuren School, students in these specialized classes tend to perform better academically and are more engaged in their studies. For instance, students in the science stream have access to advanced science labs and experienced science teachers, which enhances their understanding of complex scientific concepts. Similarly, students in the arts stream are provided with specialized art facilities and instruction, fostering their creative talents.

Data from the school's internal assessments and external standardized tests support the effectiveness of this class division. In the 2020-2021 academic year, students in the science stream achieved an average score of 95% in their science subjects, compared to 85% for students in the general stream. Additionally, the arts stream students consistently ranked in the top 10% in national art competitions. These statistics underscore the positive impact of class division on student performance and engagement.

Moreover, the school's approach to class division is aligned with international educational trends. Many countries, including the United States, have adopted similar tracking systems to optimize student learning. According to a report by the Organization for Economic Cooperation and Development (OECD), students in countries with tracking systems tend to have higher educational attainment and are more likely to pursue higher education.

In conclusion, Nanjing Shuren School's class division strategy is based on the principle of catering to students' diverse academic abilities and interests. The data supports the effectiveness of this approach, as it leads to improved academic performance and student engagement. This system is not only beneficial for individual students but also contributes to the overall educational excellence of the school.
