The International Baccalaureate Diploma Programme is a two-year programme for entrance to international universities. It is designed and supervised by the International Baccalaureate Organization and offered in over 1500 schools worldwide.

The Computer Science course is offered in two levels (Standard and High Level). The Standard Level course covers basic elements of Computer Science (Computer Architecture — Number systems — Digital data representation — Operating Systems — Computer Networks — Compilers — Software Engineering) and programming in Java. The High Level course additionally includes further details on all the above subjects, covers further areas of Computer Science (File and Database Organization — Computational Complexity) and of programming (Object Oriented programming — Data Structures). Within the course, students develop a complete Java application and fully document the development process.
