About IB

IB World School LogoWhat is IB

The International Baccalaureate (IB) Diploma Program is a rigorous pre-university course of studies, leading to examinations that meet the needs of highly motivated secondary school students. IB is a nonprofit educational foundation founded in the 1960’s and based in Geneva, Switzerland. It has 1,464 schools in 115 countries. There are more than 485 IB programs in North America.

IBO grew out of efforts to establish a common curriculum and university entry credential and the idealistic vision that a shared academic experience emphasizing critical thinking and exposure to a variety of viewpoints would encourage intercultural understanding and acceptance of others. The goal of education is to provide young people with the values and opportunities that will enable them to develop sound judgment and to make wise choices. This demanding and comprehensive two-year curriculum’s aim is to help students learn how to learn, how to evaluate information critically, how to analyze, how to reach thoughtful conclusions, and how to communicate.

IB Mission Statement

The International Baccalaureate® aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect.

To this end the organization works with schools, governments and international organizations to develop challenging programmes of international education and rigorous assessment.

These programmes encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.

What is the Extended Essay (EE)?
The extended essay (EE) is an in-depth study of a focused topic chosen from the list of available Diploma Programme subjects.  This is normally one of the student's six chosen subjects for those taking the IB diploma, or a subject that a student has a background in.  It is intended to promote academic research and writing skills, providing students with an opportunity to engage in personal research in a topic of their own choice, under the guidance of a supervisor (appropriately qualified member of the staff within the school).  This leads to a major piece of formally presented, structured writing, in which ideas and findings are communicated in a reasoned and coherent manner, appropriate to the subject chosen. Click on the "EE Subject Brief" below for more details.

IB Grade Scale


Each academic subject is assessed on a scale of 1 (minimum) to 7 (maximum) with 4 considered the "passing grade". In all IB subjects this grade is arrived at through internally as well as externally assessed or moderated work, throughout the two-year program with the final examination. Following are the approximate grade scales used by the IB:

IB Grade % Range Description
7 80 - 100 Excellent
6 68 - 79 Very Good
5 55 - 67 Good
4 45 - 54 Satisfactory
3 35 - 44 Mediocre
2 25 - 34 Poor
1 0 - 24 Very Poor

To achieve the IB Diploma, therefore, a student should achieve a minimum of 24 IB points (IB grade 4 in 6 subjects) with the maximum possible diploma score being 45 points (IB grade 7 in 6 subjects plus 3 bonus points). However, there are specific IB requirements which mean that a student scoring a 1 in any subject is not awarded the Diploma, even if the total score is 24 or greater. Similarly, a student scoring a 3 in one subject at HL still needs to reach a total of 12 points at HL, or an overall Diploma total of 28 points.

For this reason, for school purposes, we recommend that students aim for a total of 28 points with no failing conditions in order to be considered strong IB Diploma candidates.
