1 IB Diploma Programme Candidates may register for a modified set of subjects instead of attempting the full complement of requirements for the IB Diploma and receive only a certificate of examination results. An IB Diploma candidate who does not pass the requirements for the IB Diploma will also only receive a certificate of results for their examinations. A candidate who meets all of the requirements for the IB Diploma receives the IB Diploma as well as a certificate of their results. Fewer candidates worldwide attempt the full IB Diploma than take individual subjects and examinations for certificates only.

2 30 IB points arejust above the IB World Average andare equivalent to an average IB grade of 5 (good). Many North American universities give university course credit for grades of 5 or better, especially at the Higher Level.

3 36IB points are equivalent to an average IB grade of 6 (very good). Many North American Universities give a full year of university credit at considerable savings to the student or the possibility of graduating with a double major in 4 years. Only 17-18% of IB candidates around the world achieve 36IB points or greater. Approximately 5.5% of IB candidates earn 40 points or better and only about 0.2% earn the maximum 45 points.
