“…As evident from a reading of Kolen and Brennan (2004), many studies have explored consistency of scaled scores. Typically an old test form is spiraled, either in intact form or in sections, along with a new form.…”

This study uses historical data to explore the consistency of SAT ® I: Reasoning Test score conversions and to examine trends in scaled score means. During the period from April 1995 to December 2003, both Verbal (V) and Math (M) means display substantial seasonality, and a slight increasing trend for both is observed. SAT Math means increase more than SAT Verbal means. Several statistical indices indicate that, during the period under study, raw-to-scale conversions are very stable, although conversions for extreme raw score points are less stable than are other conversions.

This report summarizes the performance of the Imaging Informatics Professional (IIP) examination from 2009 to 2011 (six exam administrations). Results show that the IIP exam is a reliable measuring instrument that is functioning well to consistently classify candidates as passing or failing. An analysis of the section scores revealed that content in the Image Management, Systems Management, and Clinical Engineering sections of the exam were somewhat more difficult than the content in the other sections. The authors discuss how future candidates may use this information to help hone their study strategies. By all indications, the IIP examination appears to be statistically functioning as a high-quality certification measuring instrument.

“…However, for W, the zero line in Figure 7 is below the lower ASEE band, which may indicate that the scale drift in W is caused by sources other than random equating error. (Haberman, Guo, Liu, & Dorans, 2008 (Dorans, 2002), the ACT assessment rescaling (Brennan, 1989), and the ITBS periodical rescaling (Kolen & Brennan, 2004).…”

“…For a testing program that administers multiple test forms over successive years, equating is used to adjust test scores so that scores from different administrations are comparable. However, over time, test content evolution, change in the composition of the groups of examinees, and equating errors may result in scale drift, where this drift is defined to be a change in the interpretation that can be validly attached to scores on the score scale (Haberman & Dorans, 2011;Kolen & Brennan, 2004;Livingston, 2004). Even random error in equating can add up to a noticeable scale drift (Guo, 2010;Haberman, 2010).…”
