Abstract:
The purpose of the present study was to examine the psychometric properties of a new test of spelling achievement. Using a large sample of participating students from grades 2-4 (N = 580), results pointed to the existence of one latent spelling dimension, which was verified across grade and using multiple measurement points. Indices of reliability and internal consistency were adequate suggesting the stability of the instrument. A secondary purpose of the present study was to examine the presence of language biases across cultures. For that purpose a series of Differential Item Functioning tests were run to examine whether specific words were significantly more difficult for immigrant students compared to Greeks. By applying the Rasch model, results indicated that very few words presented themselves as significantly more challenging for immigrant students compared to Greeks. Last, by calibrating item difficulties a new ordering of the scale was proposed.
