IB Diploma

The International Baccalaureate Diploma Programme (IBDP) is an academically challenging and balanced educational programme for 16 to 19-year-olds that seeks to develop intellectual, social, emotional and physical well-being.  

The DP is one of four courses offered by the IB Organization. It is widely regarded as a high-quality, challenging educational programme well-suited to a worldwide community of schools aiming to create a better, more peaceful world. The aim of the IB is to provide students with values, opportunities and experiences that enable them to contribute to a global community. 

This 2-year programme values critical-thinking abilities and creativity in analysis, enabling a comprehensive learning experience with a strong physical, intellectual, emotional and ethical component. Students undertake 6 optional subjects and 3 compulsory subjects to form a personalised course suited to their interests and future aspirations.

Benefits of the IBDP

The IB Diploma Programme option offers a number of benefits for senior students seeking a globally-accepted course. At our school, graduates gain a senior education that encourages them to understand the world around them. The course prompts participants to ask questions and examine subject material using evaluation techniques and critical analysis.

To this end, the IB DP supports learners in the final stage of their schooling by offering a framework in which they can acquire and comprehend subjects in a more profound way. During the course, students understand the importance of knowledge more comprehensively and can apply it beyond the school environment.

IB Diploma Evaluation

Internal Assessment

Some student work is assessed by their IB teachers over the duration of the course. This procedure is part of the Internal Assessment component in which teachers mark individual pieces of work. This grade counts as a percentage of the student’s overall IB score.

Mock Exams

Over the course of the two years of the Diploma Programme, students will undergo Mock Exams. This type of assessment will include all the written examination papers for all the subjects and will be carried out in exam conditions. The purpose of these exams is to acquaint students with exam procedures and regulations as well as help students assess their knowledge and, as a result, construct an effective revision plan.

Predicted Grades

The Predicted Grade (PG) is the teacher’s prediction of the grade the candidate is expected to achieve in the subject taught. The grade is estimated in accordance with all of the evidence of the candidate’s work and the teacher’s knowledge of the IB standards and criteria.

External Assessment

External Assessment refers to work that is conducted and orientated by teachers and then graded externally by examiners. End-of-course exams are the main instruments of external assessment, but this also includes work such as the Extended Essay and the TOK essay.

To achieve the IB Diploma, there are several requirements, outlined in the IB Guide. Among other requirements, we highlight the following:

  • Failure to comply with the requirements for CAS
  • A total score lower than 24 points
  • Obtaining grade N in any subject
  • Obtaining grade E in Theory of Knowledge or Extended Essay
  • Achieving grade 1 in any subject or level
  • Obtaining grade 2 in three or more subjects (SL or HL)
  • Achieving grade 3 or lower in four or more subjects (SL or HL)
  • Achieving 12 points or lower in the HL subjects (for candidates who enrolled in four HL subjects, the top three results will be considered)
  • Achieving 9 points or lower in SL subjects (for candidates who have enrolled in two SL disciplines, they must obtain at least 5 SL points)
