In 1964 American educational psychologist at the University of Connecticut (Storrs) Ellis Batten Page, inspired by developments in computational linguistics and artificial intelligence, began research on automated essay scoring. Page published his initial research in 1967 as "Statistical and linguistic strategies in the computer grading of essays," Coling 1967: Conférence Internationale sur le Traitement Automatique des Langues, Grenoble, France, August 1967. The same year he also published "The imminence of grading essays by computer," Phi Delta Kappan, 47 (1967) 238-243. The following year he published, with Dieter H. Paulus The analysis of essays by computer (Final report, Project No. 6-1318). Washington, D. C.: Department of Health, Education, and Welfare; Office of Education; Bureau of Research. That year he published his successful work with a program he called Project Essay Grade (PEG) in "The Use of the Computer in Analyzing Student Essays," International Review of Education, 14(3), 253-263. Page's work is considered the beginning of automated essay scoring, the development of which could not become cost effective until computing became far cheaper and more pervasive in the 1990s.
Later at Duke University, Page renewed his development and research in automated scoring and, in 1993, formed Tru-Judge, Inc., anticipating the potential for commercial applications of the software. In 2002, and in declining health, Page sold the intellectual property assets of Tru-Judge to Measurement Incorporated, educational company that provides achievement tests and scoring services for state governments, other testing companies and various organizations and institutions.
