The Computer Technology Institute and Press “DIOPHANTUS” (CTI) was founded in 1985 as the “Computer Technology Institute” with its headquarters in Patras, as a Non Profit Private Legal Entity, supervised by the General Secretariat of Research and Technology, (Presidential Decree 9/1985).

Since 1992 CTI has been supervised by the Greek Ministry of Education and Religious Affairs as a financially, administratively and scientifically independent institution. In 2001 it was renamed as “Research Academic Computer Technology Institute” (Law 2909, art. 2).

Under the new law 3966/2011 its name was changed to “Computer Technology Institute and Press “DIOPHANTUS”” and it was established as the technological pillar supporting ICT in education and as the publishing body of Greek school textbooks and electronic educational material.

CTI is also responsible for the administration of the Greek School Network, the largest user network in Greece.

The organization’s successful development is attributed to its executives and staff, beginning with its former Presidents/Directors, who laid the foundations for building a modern research institution in the Greek peripheral region.
