摘要:In view of the high-stakes character of university admission procedures the validity of instruments used is crucial in avoiding both false negatives (unjustly rejected) and false positives (unjustly admitted). Researching ‘predictive validity’ is a way to find out more about the false positives: do high scores on an admission test indeed promise high scores in university? Unfortunately this tells us nothing about the false negatives, the unjustly rejected, because they do not find themselves in higher education. How can we improve admission procedures to decrease both errors and increase fairness? The paper will present approaches and research aimed at increasing the validity of admission tests, and present approaches from The Netherlands, Georgia and Israel. As International Consultants for the Ukrainian Standardized External Testing Initiative (USETI) the authors are advising the Ukrainian Centre for Education Quality Assessment in its development of admission testing and with this paper wish to encourage the introduction of validity research in Ukraine.
