Fumiko Samejima (1930–c2021) was a prominent Japanese-born psychometrician best known for her development of the Graded Response Model (GRM)[1], a fundamental approach in Item Response Theory (IRT). Her innovative methods became influential in psychological and educational measurement, particularly in improving the accuracy of tests involving Likert-scale questions and other graded responses. She published her seminal paper “Estimation of Latent Ability Using a Response Pattern of Graded Scores” in 1969.[2] This publication became a foundational reference in psychometric literature, significantly advancing the analysis of ordered categorical data.[3]

Fumiko served as President of the Psychometric Society (1996-1997)[4]. She also received various awards during her life including Outstanding Technical Contribution from the National Council on Measurement in Education (1991)[5].
