True Light Girls' College (TLGC, Chinese: 真光女書院) is a Christian girls' secondary school in Kowloon, Hong Kong. It was founded in 1973, to commemorate the centenary of the first True Light Middle School, which was founded in 1872 in Guangzhou by an American missionary, Ms Harriet Noyes. It is run by the Kowloon True Light Middle School Management Board with assistance of the Hong Kong Council of the Church of Christ in China. The school is an aided EMI secondary school. There are 20 classrooms, 12 special rooms, a hall, a library, a covered playground, a canteen and two basketball courts. Since the school was built according to the standards 30 years ago, a lot of effort has been made to improve the basic facilities of the school premises to meet the needs of the fast changing society. A new annex will be completed in mid-2005. There are 24 classes: 4 classes at each level from S1 to S5 (in S4 and S5 there are 3 Arts classes (Class A, B and C) and 1 Science class (Class D) in each Form) and 2 classes each (1 Arts class and 1 Science class) at S6 and S7.
