A comparison study of IRT calibration methods for mixed-format tests in vertical scaling

The purpose of this dissertation was to investigate how different Item Response Theory (IRT)-based calibration methods affect student achievement growth pattern recovery. Ninety-six vertical scales (4 × 2 × 2 × 2 ×3) were constructed using different combinations of IRT calibration methods (separate, pair-wise concurrent, semiconcurrent, and concurrent), lengths of common-item set (10 vs. 20 com...
