Abstract:

In the context of scaling with Item Response Theory, the choice of parameter calibration methods is an essential factor that can affect the results of vertical scaling. Existing research has obtained consistent results on the relative performance of some calibration methods and has proposed many new calibration methods to obtain better scaling results. In addition to further exploration in existing framework to form a comprehensive research system, future research should investigate the performance of the calibration methods with related disciplines on the basis of a deep understanding of the nature of achievement growth, as well as examine the best match of particular calibration methods and particular research conditions and scaling situations.

Key words: vertical scaling, parameter calibration, achievement growth, developmental educational assessment, scale maintenance
