Description

The TCALS (Test de Connaissance en Anglais Langue Seconde) is an aptitude test of English language as a second language in the French speaking college of Outaouais (Gatineau, QC, Canada). The test consists of 85 items and is administered every year to newly incoming students. The item parameters of the year 1998 have been estimated under the 3PL model. Inattention parameters are therefore fixed to one. Subgroups of items are also included for content balancing purposes.
