International Association for Computerized Adaptive Testing

2014 IACAT Conference

The 2014 IACAT conference is will be held on October 8 - 10, 2014, in Princeton New Jersey, U.S.A.  The conference is being coordinated by Educational Testing Service.  All researchers and practitioners interested in psychometrics and adaptive testing are welcome to attend.  Click here to view the conference program.

What is IACAT?

The International Association for Computerized Adaptive Testing (IACAT) is a tax-exempt nonprofit professional and scientific organization intended to promote adaptive testing. (See our Mission Statement for more information.) The organization was formulated in 2009 and founded in 2010.

Please see our extensive bibliography of CAT articles.


Currently membership is free and we invite anyone interested in adaptive testing to join. You only have to create a User account on this system  to be a member.  Members have access to the Forums, where issues in CAT research and applications can be discussed.   Members also can vote for members of the Board of Directors and hold office in IACAT.

Journal of Computerized Adaptive Testing

Our new Journal, The Journal of Computerized Adaptive Testing (JCAT) is a peer-reviewed electronic journal designed to advance the science and practice of computerized adaptive testing (CAT) by publishing empirical research reports, theoretical papers, and integrative critical reviews of topics directly related to CAT (e.g., item selection algorithms, security algorithms, multistage designs, examinee reactions to CAT, DIF in CAT, item bank development, the psychometrics of CAT) and on important ancillary topics (e.g., innovative item types, assessment engineering, psychometric models, issues surrounding the technology of adaptive testing, or validity studies).

For further information about JCAT, see the link under Resources.

CAT Bibliography

Our CAT Bibliography (which you can find under Resources) has over 2,000 references and is growing, thanks to our Bibliography Manager, Vince Maurelli, and Zhen Li, Jerry Melican, and Shungwon Ro who each are monitoring several journals for new CAT literature .  We welcome your contributions to this important resource.  Please send your CAT references and papers to IACAT Bibliography.
