This paper presents the application of unidimensional and multidimensional item response theory models on a multi- and interdisciplinary test that was part of a college admission process. Even though the test comprised contents from the many high school subjects, we have managed to set up a unidimensional model of the item response theory and establish a pedagogically sound scale. However, by using the multidimensional approach, we have managed to identify three predominant latent traits: logical reasoning, reading comprehension and proficiency in English. This paper also reports on some trials carried out with the positioning and the assessment of items in the intersection of the logical reasoning and reading comprehension latent traits, both still recent additions to the educational assessment studies.

Keywords : Item Response Theory; Dimensionality; Educational Assessment; Admission Test.
