2011: The first half – IRT analysis and CAT workshops


The first half of 2011 has been quite busy at ASC.  I have had the opportunity to visit Malaysia, India, and China for workshops on IRT analysis and adaptive testing.  It is exciting to see the growing interest for advanced psychometrics in those countries, and I am thankful to my friends for the chances to visit. The workshop in Malaysia was hosted by MIMOS Berhad, the one in India by the Ministry of Defence, and the one in China by Jiaxing University.

ASC has also presented at two conferences this spring, the Association of Test Publishers and the National Council for Measurement in Education.  Papers are available at our research page, https://assess.com/research.php.

IRT analysis and CAT software

ASC has also made major strides in its software.  FastTEST Web (www.fasttestweb.com) has ever-expanding functionality, with a focus on item response theory and computerized adaptive testing.  It remains the only publicly available platform for fully adaptive tests based on IRT.  Another important release was Xcalibre 4.1, which provides superior output for IRT analysis, as well as being the only IRT analysis program that is point-and-click.  That is, no DOS-style command code is needed, which makes IRT much more accessible to researchers and practitioners in a wide variety of fields.

Nathan Thompson, PhD

Nathan Thompson earned his PhD in Psychometrics from the University of Minnesota, with a focus on computerized adaptive testing. His undergraduate degree was from Luther College with a triple major of Mathematics, Psychology, and Latin. He is primarily interested in the use of AI and software automation to augment and replace the work done by psychometricians, which has provided extensive experience in software design and programming. Dr. Thompson has published over 100 journal articles and conference presentations, but his favorite remains https://pareonline.net/getvn.asp?v=16&n=1.
