Adult Diagnostic Reading Inventory (ADRI) provides placement and diagnostic information and identifies reading patterns, enabling you to choose effective teaching strategies. This manual contains a word list, 40 graded passages that range in readability from Grades 1 to 12, and a combination of factual and inference comprehension questions. As well, the manual provides step-by-step instruction on how to score and interpret ADRI. (Alternate-form reliability was established by piloting ADRI with over 1500 adult basic education students.) Please note that ADRI is designed for individual testing situations rather than group testing. You need to purchase only one copy of this test, as passages and questions can be photocopied.
