Robustness of the School-Level IRT Model.
Tate, Richard L.
Journal of Educational Measurement, v32 n2 p145-62 Sum 1995
Robustness of the school-level item response theoretic (IRT) model to violations of distributional assumptions was studied in a computer simulation. In situations where school-level precision might be acceptable for real school comparisons, expected a posteriori estimates of school ability were robust over a range of violations and conditions.
