The Beginners Guide to the IB Program
Understand the International Baccalaureate (IB) program: its diploma structure, core components (Extended Essay, CAS, TOK), curriculum, and benefits for university success.

What is the IB program?
The International Baccalaureate (IB) is an exciting program for students to be a part of. Here’s a guide to everything you need to know about the course and exactly what to expect.
The International Baccalaureate is a program that forms part of secondary school studies. It can feel daunting to beginners, as there are course codes and acronyms but you’ll soon become acquainted with it all.
The IB diploma was designed in Switzerland in the 1960s to prepare students between the ages of 16 and 19 for success at university and life beyond. It is an academically challenging program of study, allowing students from around the world the opportunity to earn a rigorous, internationally recognized diploma.
This diploma can be used for entry into top universities from around the world.
What does the IB diploma cover?
To earn an IB Diploma, students are required to meet a set of requirements. This includes classes across six subject groups as well as the passing IB exams, and completing three additional core requirements.
IB classes can be taken on their own. Alternatively these classes can be taken as part of a separate diploma (such as the American high school diploma), or as part of the two-year International Baccalaureate Diploma.
This program is typically taken during Grades 11 and 12 to help students develop “physically, intellectually, emotionally and ethically.”
This balanced approach makes a major impact on students during these crucial, final years of secondary education. It is an important program that can assist in answering common questions that arise regarding future studies, career ambitions, and personal goals.
The curriculum
As mentioned above, the IB program curriculum includes six subjects and three core requirements. Students are required to take six classroom courses taught by qualified IB Diploma teachers. This includes knowledge across languages, social studies, science, mathematics and the arts subjects.
The program is designed to develop critical thinking, active participation, research and writing skills. These skills will prepare you for the types of assignments assigned at university level.
Building your IB diploma
Students select a total of six courses – three of these are taken at higher level (HL) and three at standard level (SL). Examples of these subjects include language and literature, language acquisition, individuals and societies, sciences, mathematics, the arts.
IB Core
The IB Diploma core components challenge students to apply their knowledge and skills beyond their courses of study.
Theory of Knowledge
Theory of Knowledge asks students to reflect on the nature of knowledge, and on how we know what we claim to know.
Ways of knowing
This component encourages a combination of critical thinking and personal reflection.
Extended Essay
The extended essay is an independent, self-directed 4,000-word research report. It demands independent research, academic writing, and strong communication skills from students.
Creativity, Activity, Service
The IB Diploma program includes a range of activities to perform alongside their academic studies. This allows for hand-on experience that is creatively expressed.
The benefits of the IB program
In addition to preparing students for university, the students who enrol in this program are more likely to further their studies.
A study conducted by IB and SRI Education (PDF) reported that DP graduates in the United States experienced more positive post-secondary enrolment rates and graduation rates in comparison to average American high school students.
Another study found that students that received the full IB Diploma were more likely to enrol in higher education and graduate from a four-year institution.
There are also several longer-term outcomes for students who complete this course. While many students focus on more immediate gains of the IB program, the benefits extend far past university. A global study of IB alumni found that the IB has the potential to powerfully shape the lives of the students who participate in its programs.
Former IB students reported experiencing profound and long-lasting effects that are consistent with the goals of the IB Learner Profile in terms of student development.
Examples of these longer-term outcomes include:
- The development of international-mindedness
- A broader global perspective
- Critical thinking skills
- Analytical and writing skills
- Positive dispositions towards lifelong learning
The IB classes
The IB classes are unique from other advanced classes because they fit into the educational ecosystem created by IB. The classes are intentionally developed to promote comprehensive, interdisciplinary learning and critical thinking across different fields of study.
The IB diploma program begins in Grade 11 and focuses on three core elements:
- The theory of knowledge: reflecting on how we know what we know
- The extended essay: writing an independent research paper
- The CAS (creativity, activity, service) project: creating a project based on those three themes.
Students select classes from each of these subject groups to build their own academic path. Some of these classes are one year courses (Standard Level, SL), which require 150 hours of study, while other classes take place over two years, (Higher Level, HL), and require 240 hours of study to complete.
HL courses allow for a deeper dive into a particular field of study. These subject selections require careful thought. The courses will include theoretical and practical aspects in each class.
Having a range of different subject groups and the option to choose Standard or Higher Level courses allow students to pursue their particular academic interests while also enjoying courses from across the spectrum of the arts, sciences, and humanities.
Reasons to enrol in the IB program
The IB program is established to provide students with a balanced education, facilitate geographic and cultural mobility, and to promote international understanding. As the IB explains, students will:
- Gain an excellent breadth and depth of knowledge
- Flourish physically, intellectually, emotionally, and ethically
- Have the opportunity to study at least two languages
- Excel in traditional academic subjects
- The chance to explore the nature of knowledge through the program’s unique theory of knowledge course
Importantly, this program is also a great way to prepare for university. All in all, students will develop a well-rounded and worldly perspective that is ready to learn more at a university level.
IB courses are interdisciplinary, which means they require independent thinking, oral presentations and original research, which is akin to what is expected of university students. It is important that students are enabled to cope with demanding workloads, time management, and meeting the expectations placed on them.
University Credit for the IB student
As any student with international ambitions knows that the requirements for university admissions and transferring credits from high school can differ from one country to the next.
Before taking on IB classes or the IB diploma program, students and their parents are encouraged to speak with their guidance counsellor about how this program can be directed towards their desired program of study. College counsellors can also advise students on the potential college credits that students can earn for each successfully completed IB course and examination.
Students can usually find a clear IB credit transfer chart on the Admissions portion of each university’s website.
Depending on the IB class, students can earn between one and two-quarters of credit for certain classes in everything from Chemistry to French.
By enrolling in advance, students can economize their time, allowing them to take other courses while maintaining their progress toward their desired degree, or opt-out of certain core classes (depending on the university). Almost stress-free!
