I'm a former reading specialist, but have given away all of my materials and references. I am curious about the relatively new text stats provided by amazon.com, and realized I have forgotten the percentages for the three levels of reading....independent, instructional, and frustration. Also...which level does the Flesch-Kincaid refer to? The example used is 10.1 that would be suitable for someone with a 10th grade or higher reading level, but that could be instructional, understanding with some help,. or reading independently with complete comprehension.

I would really appreciate this information in order to select appropriate books for my grandchildren. (Have been retired for 10 years and am working in another direction.)
