Abstract: The purpose of this study was to investigate initial evidence regarding the reliability and validity of scores from a digital professional portfolio (DPP) designed to assess the instructional competencies of preservice teachers. Data were collected from 30 preservice teachers during their intern teaching experience. Data were analyzed using a variety of methods including Pearson product-moment correlation coefficients, Cronbach's alpha, and Cohen's kappa coefficient. Evidence supporting the use of the DPP was found through theoretically acceptable relationships with other teacher assessments. Weaknesses of the DPP also were identified, including low percentage of exact agreement between scorers. Directions for future research are discussed. (Contains 1 table.)
