Expertise

Leslie’s research is in the area of international large-scale assessment. Her interests include latent variable models and examining methods for comparing heterogeneous populations in international surveys.

In particular, I am interested in critically analyzing the methods used to gather data and to produce achievement scores. I am also interested in methods and models for accommodating heterogeneous populations in latent variable models.

Projects:

  • Response Time in ILSA
  • Multistage Testing.
