Since last summer I have been using a Readability Test from Joe's Web Tools to figure out reading levels for the easy reader section of the Literacy Collection. The processing department at the Library purchased reading level labels (1-12) from Gaylord. Based on the Flesch-Kincaid grade level system, I have been appyling labels to the front of our books so that we have one unified system from which to rank readability. While there are many readability factors and systems, I have found Joe's calculator to be in line with my experience with easy reading materials and as an ESL tutor and teacher. Check it out!
