Respected. Balanced. Effective.

The IB Diploma Programme is the final stage of the IB program at ISI and takes place in Grades 11 and 12. It’s a challenging but balanced program of study that prepares students for success at the university level and beyond.

The IB diploma is highly respected by institutions of higher learning in the United States and throughout the world. IB diploma students make connections across subject areas, explore the theory of knowledge, and study courses of their choice in six subject groups.


IB Success

In May of their Grade 12 year, ISI students take their IB final exams. Students are tested in each of their chosen subjects, with 20-25% of each subject evaluated internally by their ISI instructor and the remaining portion evaluated by International Baccalaureate examiners.

The IB diploma minimum pass score is 24 points out of a total 45. ISI students achieve an average of 32-33 points, and students’ success rate varies between 83 and 96%.

Students who do not pass the IB exam but meet state course requirements will still receive an Indiana Honors (Core 40) diploma, plus IB certificates in each subject for which they sat the exam and completed coursework.

Six Subject Groups

The IB diploma curriculum features six subject groups:

  • Language and literature
  • Language acquisition
  • Individuals and societies
  • Mathematics
  • Sciences
  • The Arts

Students must take one subject from each of the first five groups. For their sixth subject, they may choose either an arts subject, Chemistry, or a Foreign Language. Foreign Language classes only go ahead in Group 6 if there are sufficient numbers to run the class.

Core Requirements

In addition to their subject study, IB diploma students complete three additional core requirements:

  • The Extended Essay requires students to engage in independent research and in-depth study of a question relating to one of the subjects they are studying.
  • The Theory of Knowledge (TOK) Course requires each student to reflect on the nature of knowledge by examining different ways of knowing (perception, emotion, language, and reason) and different kinds of knowledge (scientific, artistic, mathematical, and historical).
  • Creativity, Activity, Service (CAS) requires students to actively learn from the experience of doing real tasks beyond the classroom.  Students can combine all three components or do activities related to each one separately.

Meaningful Assessment

Meaningful assessment is important for student progress in the IB Diploma Programme. But “assessment” does not always mean testing. Much of our student assessment doubles as teaching, so students do not feel over-evaluated.

Teachers assess students continually using methods specific to each subject. Students demonstrate skills and knowledge in actual learning situations, rather than being tested on rote memorization.

Students’ assessments are based on how they do compared to set standards. Students are not evaluated against the performance of other students.
