Abstract

Professor Ronald K. Hambleton (1943-2022) shaped the development of psychometrics in the United States and had a far-reaching impact on professionals interested in psychological and educational measurement worldwide. All three authors were at different times visiting researchers in the Research, Educational Measurement & Psychometrics (REMP) Program at the School of Education at the University of Massachusetts at Amherst (USA). We would like to develop these brief notes according to three main arguments of how Ron impacted our lives: Hambleton as a "professional model," Hambleton as an "educator," and the indelible imprint that Ron has left on our professional practice.
