Statistics, Psychometrics and Data Analytics in Educational Survey Assessments

Helena Jia Executive Director, National and International Assessments /ETS

Educational survey assessments are used in measuring and monitoring learning and educational progress for youth as a group, rather than as individuals. This talk offers an overview of how practitioners applying methodologies in statistics, psychometrics and data analytics in the design of educational survey assessments, as well as in the estimation of group scores nationally and internationally. I will describe several statistical approaches that are involved in the group score estimation–item response theory models, latent regression models and missing data imputation/plausible values. Recent and future research and methodology development as survey assessment data collection transitioning from paper-based to digitally-based platform will be discussed as well.
