James Sick has been a resident of Japan for 30 years, where he has taught English as a foreign language at the high school, university, and graduate school level, as well as courses and workshops on language assessment, Rasch measurement, and technology assisted language learning. His work with Rasch measurement has centered around the measurement of affective and cognitive individual differences amongst language learners, as well as the measurement of proficiency, achievement, and progress in language skills. He currently serves on the executive board of the Japan Association of Language Teaching (JALT) and writes a regular column on Rasch measurement in education for Shiken, the journal of the JALT testing and evaluation special interest group.
