This paper aims to showcase the value of implementing a Bayesian framework to analyze and report results from international large-scale assessments and provide guidance to users who want to analyse ILSA data using this approach. The motivation for this paper stems from the recognition that Bayesian statistical inference is fast becoming a popular methodological framework for the analysis of educational data generally, and large-scale assessments more specifically. The paper argues that Bayesian statistical methods can provide a more nuanced analysis of results of policy relevance compared to standard frequentist approaches commonly found in large-scale assessment reports. The data utilized for this paper comes from the Teaching and Learning International Survey (TALIS). The paper provides steps in implementing a Bayesian analysis and proposes a workflow that can be applied not only to TALIS but to large-scale assessments in general. The paper closes with a discussion of other Bayesian approaches to international large-scale assessment data, in particularly for predictive modeling.
