Diploma Pathways
The IB Diploma Programme
The International Baccalaureate (IB) Diploma Programme is a rigorous two-year course of study that was introduced at ISL in September 2000. It gives students access to college and university study throughout the world, and universities rightly perceive that a student who has completed the requirements of the IB Diploma Programme is well prepared for the demands of higher education. The IB Diploma Programme offers both breadth, in terms of the range of courses offered, and depth, in that students must take each course for two years. It is a deliberate compromise between the specialisation required by some national systems and the breadth preferred in others.

The ISL High School Diploma
ISL offers a fully recognised US High School Diploma in addition to the IB Diploma, as ISL is accredited by the New England Association of Schools and Colleges (NEASC). The IB Diploma and the ISL High School Diploma are two separate qualifications. The IB Diploma is a more demanding programme, and students who successfully complete it are also awarded the ISL High School Diploma. However, several students each year choose to focus their efforts on achieving the ISL High School Diploma only, rather than both qualifications simultaneously. This involves taking individual courses that lead to the same final IB examinations, and results in a portfolio of official IB course results that are recognized by universities in combination with the ISL High School Diploma.

The IB Diploma Curriculum
Students take six subjects for the full IB Diploma; three at higher level (HL) and three at standard level (SL). Each student must take one course from each of six groups, although they may substitute the arts for an additional subject from one of the other groups. In addition to this, every student is required to complete the three core elements of theory of knowledge (TOK), extended essay (EE) and creativity, activity, service (CAS).
Generally, subjects studied at higher level will reflect the student’s area of interest and specialisation, and will be covered in greater depth and breadth than subjects studied at standard level. Higher level courses involve about 50% more work and are also more demanding.
