Samuel Sollerman

Samuel Sollerman serves as Director of PRIM (a research and test development group) and Senior Lecturer at Stockholm University's Department of Teaching and Learning. His work focuses on the assessment of knowledge and competence, primarily in mathematics education.

His research interests center on large-scale measurements of mathematical knowledge, with particular emphasis on validity issues in international assessments like PISA and TIMSS. He also investigates Swedish national examinations in mathematics, exploring areas such as digitalization, student performance, and assessment methodologies.

Sollerman holds significant responsibilities in Sweden's educational assessment landscape, serving as project manager for national mathematics tests across multiple grade levels and as the Swedish project manager for international studies including PISA and TIMSS. He is also involved in the national entrance test for higher education and the PIAAC study.

As coordinator in the research school ASSESS (Assessment of Knowledge in Educational Systems), he supervises doctoral students and teaches courses on assessment, quantitative methods, and large-scale assessments in mathematics at both master's and postgraduate levels. His recent publications demonstrate expertise in international comparative studies, assessment validity, digital testing transition, and student emotional responses to mathematics education.

Sollerman's work bridges research, policy, and practice in educational assessment, contributing to both national and international understanding of mathematics assessment systems and their implications for educational practice and policy development.
