All titles included on the MRB Reading Recovery® Approved Book List have been field-tested by the Reading Recovery® Council of North America. Books range from Reading Recovery® Level 1 (comparable to Fountas & Pinnell Guided Reading Level A) to Level 20 (Fountas & Pinnell Levels L-M). See a Reading Level Correlation Chart that compares different literacy leveling systems here. The books on the approved book list were selected by the Reading Recovery® Council of North America because of their ability to support a young reader’s strategic development, as well as, to encourage problem-solving skills.
