The CTEQ Collaboration was formed in 1991 by a group of theorists and experimentalists in response to a call from the American Physical Society Division of Particles and Fields to emphasize ``physics in four dimensions.'' The concern was that the experimental programs at Fermilab and the SSC that was under construction would need theoretical guidance if precision test of QCD and the Standard Model were to be carried out. The original group, of which I was a founding member, consisted of twelve theorists and experimentalists. Today that number has grown to twenty-four. The acronym CTEQ was chosen to stand for Coordinated Theoretical and Experimental Tests of QCD and the Standard Model.

CTEQ originally received funding from the Texas National Research Laboratory Commission as part of the Superconducting Super Collider project. After the SSC was cancelled in 1993 CTEQ continued using funding provided to the individual members' research programs from the Department of Energy and the National Science Foundation. These agencies and various national laboratories have also been instrumental in funding our outreach activities described below.

The main CTEQ activities consist of organizing international summer schools, hosting workshops, and the work of the Global Fitting Group on the construction of sets of parton distribution functions (pdfs). A complete list of the summer schools and workshops as well as links to the pdf sets can be found on the CTEQ web site. Many of the summer school lectures can be found there, as well, in addition to other links which may prove useful to researchers in QCD. The CTEQ Collaboration also created a Handbook of Perturbative QCD. An updated version of this can be found on our web site.

In November 2005 I was elected co-spokesperson of CTEQ. A complete list of the current members may be found on the CTEQ web site.
