The Standardized Reading Inventory-Second Edition (SRI-2) differs from the first edition in important ways. In addition to being criterion-referenced, the instrument is now norm-referenced. Also, the subtests include a measure of vocabulary proficiency and a supplemental measure of predictive comprehension.
Designed like an informal reading inventory, each of the two forms consists of 10 graded passages, ranging from the lowest reading level (preprimer) to the highest level (eighth grade). Each passage incorporates key words extracted from five popular basal reading series to form a new word list for primary, intermediate, and advanced readers.
