  1. Note. b i item difficulty, SE standard error. Items are identified by the text to which they are related (RB Rita and Bruno, AN the animals, LB lost bread, TT Two twins almost alike), followed by a number. The comprehension level assessed by each item is presented in superscript (LC literal comprehension, IC inferential comprehension, R reorganization, CC critical comprehension). Common items to the TRC-n-3 appear in bold. A = Anchor item with a fixed value
