Established as a department in 1999, ITD's history dates from 1969 when it was first created as the Central Data Processing Division with the Office of Management and Budget. The division set up an electronic data processing center used by all state agencies except the institutions of higher education, Job Service, and the office of the Adjutant General. The Higher Education Computer Network (HECN) was funded after a 1969-70 interim legislative study. In 1981 the director of CDP was directed to supervise all executive branch agency data processing activities and to approve data processing equipment acquisitions.
The division was renamed the Information Services Division in 1989. At this time, the division was required to prepare guidelines for agency information technology plans, develop a statewide plan based on those plans, develop statewide information technology policies, standards, and guidelines, coordinate services with political subdivisions and systems and services with higher education, and report non-compliance to the legislature.
