Academic interests

Isa Steinmann is a postdoctoral researcher at the Centre for Educational Measurement at the University of Oslo (CEMO) in Norway and at the Center for Research on Education and School Development (IFS) at TU Dortmund University in Germany. In her research, she mostly uses international large-scale assessment data for secondary analysis to determine how education systems and schools affect student achievement and educational inequalities. In this field, she enjoys applying methods that aim for causal inference from observational data. Another strand of her research investigates how properties of the international large-scale assessments affect their results and interact with the respondents.
