Self-ratings encourage metacognitive awareness, comprehension questions test accuracy, and hints enable greater success and independence. Score reports make it easy to see progress (and write progress notes) along the three graded levels: * Level 1: Shorter passages of 50 words or less, written around a Grade 0 – 1 reading level. Three questions after each passage test comprehension. ** Level 2: Medium passages of 50-150 words, written around Grade 2 – 3 reading level. Four questions appear to see how well you understood. *** Level 3: Harder passages get you ready for the texts you want to read. 150 – 600 words and Grade 3 – 6 reading level with five questions each. Adult readers will enjoy these functional and entertaining passages as they get back to reading the pages and screens in their own lives. Speech-language pathologists will love having so many modern reading passages with carefully-crafted questions at hand to teach strategies.
