Centre for Person-Computer Studies
The Centre for Person-Computer Studies (CPCS) was formed in the UK in 1968 as a not-for-profit organization to support research and development in interactive computers and their application. It relocated to Canada in 1982, and its research and development activities have continued to be funded through a combination of grants, donations, consultancy and sale of software.

A major objective of CPCS is to promote understanding and application of personal construct psychology by making constructivist psychological techniques as widely available as possible.

CPCS has made repertory grid elicitation and analysis available for the last decade as interactive web services through a freely accessible WebGrid server at the University of Calgary. This has been used by tens of thousands of colleagues world-wide, most of whom we do not know, and has supported research resulting in numerous graduate theses and research papers as well as classroom and personal studies.

CPCS has also supported access to stand-alone repertory grid elicitation and analysis programs by issuing the PLANET suite for the Apple II in 1978, porting the programs to the Macintosh in 1986 as RepGrid, and extending them for knowledge-based system development as KSS0, NEXTRA and KSSn.

In 2004 it developed new versions of the programs to run under Microsoft Windows XP and Apple Macintosh OS X, integrating them with its representation network tools as Rep IV that incorporates RepGrid, SocioGrids, WebGrid and RepNet.

In order to support constructivist educators and students a simplified Personal version of Rep IV has been made freely available for non-commercial use.

CPCS has a close association with Knowledge Support Systems Inc, which specializes in commercial and industrial applications of knowledge-based systems, and offers extended and customizable versions of the programs for use in market research, knowledge management, and related applications.
