The Psychometrics Centre

Cambridge Judge Business School

The Psychometrics Centre and Speech Link have a long history of collaboration on interesting psychometric questions arising from Speech Link's provision of advanced linguistic assessments. Our current project covers several areas, including:

  • Analysing data to understand the key stages of development in child language ability and evaluate the effectiveness of interventions
  • Conducting CAT simulations on response data from Speech Link's tests to support business decisions
  • Advising on order effects and distractor analyses to optimise response data quality and test resilience
  • Providing recommendations on the implementation of computer-adaptive testing engines
  • Concurrent estimation of item parameters using IRT methods
