Four vacant schools are being offered for bids as potential sites for international schools.
The move is part of a raft of government measures to boost the number of school places in the city.
The Education Bureau says the sites - two in Kowloon and two on Hong Kong Island - are open to applications from all non-profit-making international-school operators over the next two months.
The deadline for bids is on August 27.
The biggest and newest among the sites is the 11-year-old former premises of Cheng Jack Yiu School in Stanley. It has 30 classrooms and six special-purpose rooms covering 4,730 square metres.
The smallest is the 43-year-old Yan Kow School in Choi Hung, at 1,679 square metres.
The two other sites are St Mark's School in Shau Kei Wan - the oldest site at 56 years old - and Sing Yin Secondary School in Lam Tin.
