The Kick-off Ceremony of Mainland-Hong Kong Teachers Exchange and Collaboration Programme (2023/24) was held on 23 September 2023. In the 2023/24 school year, more than 30 Mainland expert teachers (METs) arrived Hong Kong to exchange and collaborate with the local kindergartens, primary and secondary schools. During the Kick-off Ceremony, METs and a school shared their collaboration experience in the last year. The METs were then engaged in professional exchange activities with the participating schools of the 2023/24 s.y. in groups.
