Dimiter Dimitrov joined the faculty of the Graduate School of Education of George Mason University in the Fall of 2003 as an Associate Professor of Quantitative Research Methods. Prior to coming to Mason, he was an Associate Professor of Evaluation and Measurement in the Graduate School of Education at Kent State University (1995-2003), where he has taught graduate courses in Multivariate Statistics, Quantitative Research Methods, Measurement (Classical and Item Response Theory), and Generalizability Theory.

Dr. Dimiter Dimitrov received his bachelor's degree in mathematics from the University of Sofia "Kl. Ohridski", Bulgaria. He is a dual Ph.D. - in 1984 he received his (first) Ph.D. in Mathematics Education from the University of Sofia, Bulgaria, and in 1995 he received a Ph.D. in Educational Measurement and Statistics from the Department of Educational Psychology in Southern Illinois University at Carbondale.

Dr. Dimitrov's current research interests include:

• Presenting expected true-score measures as a function of item response theory estimates of item parameters,
• Adjustment of estimations with the Rasch model,
• Theoretical and methodological issues of reliability,
• Validation of cognitive structures using methods of item response theory and structural equation modeling, and
• Psychometric analysis of student performance and other behavioral variables.
