What is a Lexile Ranking? 

    A Lexile Ranking is a number calculated upon several factors, such as sentence length, and word-frequency characteristics, that indicates how readable a particular text is by a child at a particular grade level.   For information on how it came about in 1998, and by what formula the numbers are calculated, see:  http://www.lexile.com

For an excellent analysis of the pluses and minuses of the Lexile Ranking system, plus other readability ranking methods, see Reading Instruction Today: Matching Books and Readers by Linda Diekman:  http://courseweb.lis.illinois.edu/~diekman/LIS590/Matching.htm
