All schools should imbue students with the spirit of service, especially those with students who have done well, said Prime Minister Lee Hsien Loong at the 80th anniversary of CHIJ St Nicholas Girls' School on Tuesday.

He said while the students may have succeeded through talent and hard work, they must also realise that they live in a meritocratic system that rewards them for their abilities and develops them to their potential, as well as, in a society that cheers those who succeed instead of cutting them down.

"It is right that you give back to society, and strengthen the system that has enabled you to succeed," he said.

Mr Lee also affirmed that Special Assistance Plan schools like St Nicholas remained an important part of the school system in developing students with a deep understanding of Chinese culture, but urged them to learn to understand and relate with other ethnic groups. He said: "If we do it well, it gives us a unique strength - a deep understanding of one's culture, within a multi-cultural context - which will enable you to continue maintaining harmony in Singapore, and also to thrive in a globalised world."

Mr Lee officially opened the re-built campus of CHIJ St Nicholas Girls' School at Ang Mo Kio St 13, which was funded mainly by the Government and which has a new indoor sports hall, and music and dance studios.

He said the Government is rebuilding old campuses and investing in new facilities, and encouraging schools to come up with creative ideas to improve their facilities.
