The Junior College (Grades 11 and 12) is the extension of the Secondary School. After the IGCSE level examinations in Secondary 4, students may apply for admission to the Junior College (JC).  The two years spent here culminate in a GCE ‘A’ Level Certificate which is one of the most recognized international qualifications used for university admission around the globe

General characteristics of the SIS JC Curriculum
Character building is the prime focus of the Junior College. Students explore issues like morals and key human attributes needed to face a world filled with challenges. On-going political developments are discussed. International conflicts and environmental issues are put in perspective.  Attributes like integrity, courage, fortitude, honesty, and loyalty, are encouraged and emphasised. Much of this is integrated in the Projects that they do and in the curriculum that they will be exposed to. In short, students are expected to see beyond themselves, their family and their friends, and look towards society and the world they live in.

Subjects Offered
A key component of the JC curriculum is the Community Service Programme which extends from the secondary school. Other courses offered are: English Language and Literature, Mathematics, Biology, Physics, Chemistry, Business Studies, Accounting, Economics and Physical Education. (More subjects may be added depending on student numbers and the choices they make)
