Rašov model — Jednoparamentarska logistička IRT

Rašov model, koji je uveo Georg Raš 1960. godine, najjednostavniji je član porodice teorije odziva na stavke (IRT). On dodeljuje jedan parametar težine svakom zadatku na testu i postavlja i težine zadataka i sposobnosti osoba na istu logit skalu, omogućavajući direktno, nezavisno od uzorka, poređenje zadataka i osoba.
