Powerpoint Presentation at AERA 2017 Annual Meeting by NIEER Assistant Research Professor Zijia Li

Summary Findings:

  • The unidimensional model provides a parsimonious and near precise solution for the dimensionality assessment of the 32-item Preschool OnlineCOR and the 8-item COR-ST
  • The graded response model showed better fit than the reduced graded response model for the 32-item Preschool OnlineCOR and the 8-item COR-ST
  • COR-ST only held partial longitudinal measurement invariance
