Psychometric Features of the General Teacher Test under the D-Scoring Model: The Case of Teacher Certification Assessment in Saudi Arabia

Dimiter M. Dimitrov, Abdullah Alsadaawi


The teachers’ knowledge and skills on general standards under the Saudi National Professional Teacher Standards is assessed with the use of the General Teacher Test (GTT) administered by the National Center for Assessment (NCA) in Saudi Arabia. This paper examines the psychometric features of the GTT in the framework of a new approach to test scoring, referred to as D-scoring model, which is used with assessments at the NCA. The stability of such features across four test forms of the GTT is also examined. The study findings provide valuable information about the accuracy of the GTT scores and the validity of their interpretation and decisions regarding the licensure of teachers.
