Grading Standards Globally
You will be able to define what a grading system is, distinguish letter-grade and numeric-scale models, and explain how GPA and cumulative grades are calculated as the basis for all comparative analysis.
You will be able to identify how historical, cultural, and institutional factors drive divergence in grading philosophies across countries, using concrete examples from European, East Asian, and North American systems.
You will be able to explain the concept of measurement invariance and articulate why establishing construct equivalence is a prerequisite for any valid cross-national comparison of academic grades.
You will be able to critically evaluate methodological approaches—such as IRT-based linking, equipercentile equating, and confirmatory factor analysis—used to achieve and test psychometric equivalence in global grading research.
