Assessing Measurement Invariance of the Teachers’ Perceptions of Grading Practices Scale across Cultures

In a cross-cultural study, it is crucial to understand whether items and the factorial structure of a survey instrument are equivalent across different cultural groups, because items might mean differently to different population groups, and thus the factorial structure of the measurement instrument might not hold across groups. The purpose of this study was to investigate the measurement invariance of the Teachers’ Perceptions of Grading Practices Scale (TPGP) across the U.S. and China using structural equation modeling. In particular, this study was designed to examine whether items and the factorial structure of the TPGP scale were equivalent across the two countries, and identify nonequivalent items if this instrument was a partially invariant measurement instrument.
