What do this year's results mean?

This years's grade awarding system returns to the IBO's pre-pandemic one. After the IB introduced “appropriate grade boundaries” in 2021 and 2022 due to the disruption caused by Covid-19, it decided that "the distribution of grades awarded for our qualifications returned close to those of May 2019."

The global average IBDP score for the May 2023 session is 30.24 points.

This compares with an average of 31.98 in 2022 when students returned to examinations following the Covid 19 pandemic, against 32.98 in 2021, when students received Teacher Assessed Grades.

The global average in the last full set of examinations taken by students in 2019 was 29.62, which was actually a lower average than those of 2018 of 29.76. While the 2023 global average is lower than last year, it, still remains 0.60 points above the 2019 average of 29.62.

A statement from the IBO states: 

"In line with other national and international awarding organisations, the profile of grade distribution returned close to pre-pandemic standards. This return to established distributions of awarded grades is aligned with university expectations and has been a phased process: results for the May 2022 and November 2022 examination sessions were closer to the results of 2019 than those of 2021". 

The two-year IBDP programme is currently offered at 23 international schools in Thailand, including five that are full IB schools. These include: Ascot International School, Bangkok Patana School, British International School, Phuket, Concordian International School, Garden International School, International School Bangkok, International School Eastern Seaboard, KIS International School, NIST International School, Pan-Asia International SchoolPrem Tinsulanonda International School, Regents International School Pattaya, Ruamrudee International School, St Andrews International School, Bangkok, St. Andrews International School, Green Valley, St. Andrews International School, Sukhumvit 107, Regent's International School, UWC Thailand International School, and Wells International School.

There are four schools currently offering the IBCP.
