The Issue of Fuzzy Concepts in Test Construction and Possible Remedies

This editorial introduces the current issue on the topic of fuzzy concepts in test construction. This issue focuses more specifically on a mixed methods approach in test construction. The quantitative aspects of testing a newly constructed assessment tool range prominently within this journal (Alonso-Arbiol & van de Vijver, 2010). However, some issues arising during the test development process cannot be dealt with using quantitative methods alone. Along with the coauthors of this editorial—experts in the application of a mixed methods approach in test construction—these issues are explored.
