The following Assessment research studies address a range of topics related to the IB educational programmes that include IB summative assessments, the DP, CP and MYP. These studies focus on assessment related issues and ensure that IB assessment and its examination processing are appropriately informed by current research.

In this study, Oxford University analysed student data from the May 2018 and 2019 DP Science exams to explain some of the differences in student achievement. They found that IB translations are of high quality.
