The transfer from junior to senior in Shenzhen for the 2026 academic year typically occurs in early June. This is consistent with the standard school calendar in China, which generally follows a two-semester system. The first semester concludes in January, and the second semester, which includes the junior year, ends in June. Students then transition to the senior year, which begins in July.

The timing of this transfer is influenced by several factors. Firstly, the Chinese education system emphasizes the importance of standardized testing, particularly the Gaokao, which is the national college entrance examination. The Gaokao is usually held in early June, and students are expected to have completed their junior year by this time to ensure they are fully prepared for the exam. This timing also aligns with the national holiday schedule, which includes the Dragon Boat Festival and the National Day holiday, providing students with a break before the intense preparation for the Gaokao.

Data from the Shenzhen Education Bureau indicates that the city's schools adhere to this standard calendar. According to the 2025-2026 school calendar released by the Shenzhen Education Bureau, the last day of the junior year is June 30, and the first day of the senior year is July 1. This confirms the typical transfer period from junior to senior in Shenzhen for the 2026 academic year.
