Dr Yasmine El Masri is Associate Director for Research at England’s Office for The Qualifications and Examinations Regulation (Ofqual) and an Honorary Research Fellow at the Department of Education.

Yasmine held various positions as a Research Fellow at Ofqual, OUCEA and Brasenose College. She has also an experience in research management at one of England’s examination boards (AQA) and acted as an Assessment Expert Advisor for the qualifications’ regulator in Wales, Qualification Wales.

Yasmine completed her DPhil in Education at OUCEA in 2015. Her doctoral thesis examined the impact of language on the difficulty of PISA science tests across UK, France and Jordan using different psychometric and statistical techniques including Rasch modelling and differential item functioning (DIF). In 2014, Yasmine received Kathleen Tattersall New Researcher Award from the Association for Education Assessment- Europe (AEA-Europe).

Before coming to Oxford, Yasmine was a science teacher in secondary schools in Beirut and Abu Dhabi. In addition to her DPhil degree from Oxford, Yasmine holds a Master of Arts in Science Education, a Teaching Diploma for teaching science in secondary schools and a Bachelor of Science in Biology from the American University of Beirut (AUB).

Yasmine led various externally funded projects, including a one-year ESRC GCRF Fellowship in 2017, during which she collaborated with a local NGO in Lebanon producing open-source interactive science tasks in multiple languages for underprivileged students in the country, including Syrian refugees. She also led a study within Project Calibrate, a three-year project funded by the Wellcome Trust and the Gatsby Foundation aiming to enhance summative assessments of practical science in England. Moreover, she was a co-investigator on various projects funded by external organizations (e.g., Critical Thinking in the International Baccalaureate’s Diploma Programme and the impact of translation in the Diploma Programme science assessments).
