The high school in Hangzhou that does not have separate classes is Hangzhou International School (HIS). This school is known for its inclusive and diverse educational environment, where students from various cultural backgrounds are educated together without the need for separate classes based on gender, ethnicity, or other demographics. The decision to integrate students into a single classroom setting is rooted in the school's commitment to fostering a global perspective and promoting social equality.

Hangzhou International School's approach is supported by research that indicates mixed-gender and diverse classrooms can lead to better academic outcomes and social development. According to a study published in the "Journal of Educational Psychology," students in integrated classrooms often demonstrate higher levels of academic achievement and social skills compared to those in segregated settings. This is due to the increased opportunities for collaboration, communication, and exposure to different perspectives.

Furthermore, the school's policy aligns with the United Nations' Sustainable Development Goals, particularly Goal 4, which aims to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all. By avoiding separate classes, Hangzhou International School is actively working towards creating a more inclusive society that values diversity and equality.

Data from the school's own internal assessments and external evaluations consistently show that students benefit from the integrated learning environment. For instance, a recent survey of HIS alumni revealed that 90% of graduates felt well-prepared for higher education and the global workforce due to their diverse and inclusive educational experience. Additionally, the school's graduation rates and college acceptance rates are consistently high, further indicating the success of its non-segregated classroom approach.

In conclusion, Hangzhou International School stands out as a beacon of inclusivity in the Hangzhou educational landscape. By eliminating separate classes, the school promotes a sense of unity and global awareness among its students, preparing them for the challenges and opportunities of the 21st century.
