PRIETO ADANEZ, Gerardo  and  DIAS VELASCO, Angela. Uso del modelo de Rasch para poner en la misma escala las puntuaciones de distintos tests. Actual. psicol. [online]. 2003, vol.19, n.106, pp. 5-23. ISSN 0258-6444.

Test users have to link scores of different instruments in several practical situations, such as academic assessment, personnel selection, change studies, item banking, cross-cultural validity studies, and differential item functioning analyses. Test linking is one of the main utilities of the Rasch model. In this paper, we show the process of linking two tests (design, data analysis and interpretation) using as anchor a commom set of items.

Keywords : Test anchoring; Test linking; Test equating; Rasch model.
