Test of Irregular Word Reading Efficiency™

By using the pronunciation of phonetically irregular words to measure reading comprehension, the TIWRE offers a rapid assessment of the examinee's reading vocabulary. Because phonetically irregular words cannot be pronounced correctly unless they are already a part of the reader's vocabulary, they are especially useful for measuring reading comprehension. The TIWRE is different from other reading comprehension assessments because it utilizes this concept and presents only phonetically irregular letters and words for pronunciation. This easy-to-administer measure is supported by validity evidence and is highly reliable. With three equivalent forms, the TIWRE provides its user with the ability to monitor changes in reading performance over relatively short periods of time with no detectable practice effect from testing itself.
