CERDAS NUNEZ, Danny  y  MONTERO ROJAS, Eiliana. Use of the Rasch model to build specification tables: Methodological proposal applied to a university selection test. Rev. Actual. Investig. Educ [online]. 2017, vol.17, n.1, pp.79-95. ISSN 1409-4703.  http://dx.doi.org/10.15517/aie.v17i1.27299.

Through quantitative approach and a descriptive analysis research, this paper presents a less known application of the Rasch Model, as a technical tool for the development and validation of specifications tables for standardized tests. The study proposes a framework to generate a specification table with processes and contents for the math context component of the undergraduate admission test used by the University of Costa Rica. It is worthwhile to remember that the standard approach to construct specifications tables in educational tests has been based on what traditionally is called “expert judgments”, with no good hold on scientific approaches. The main interest, beyond this particular application, is to detail the methodology, and show a way that could be implemented to use this frame of reference to develop and validate specification tables in a more rigorous and scientific way, supported for the empirical evidence provided by the Rasch Model, along with the knowledge and assessment of expert judges.

Palabras clave : Rasch model; specifications table; standardized testing; psychometric tests; validity.
