(1)Levels 1 and 2 are NOT nationally-normed.

The norm represents the performance of a group of students that are on the same grade level as your child. The last two norms were done in 2002 and 2007. Our company uses the 2007 norm results in our scoring process.

National norms represent the pattern of performance of all the nation’s schoolchildren. But it is important to keep in mind that children are constantly expanding their knowledge. Therefore, your child’s performance will most likely change from year to year.

The Lexile score refers to a measure provided about a person’s reading ability. It helps parents decide the appropriate level of difficulty for a book and or article, and it helps determine how well the student will be able to understand the text. According to its developer, “The Quantile Framework for Mathematics is a scientific approach that indicates the difficulty of mathematical skills and concepts. In addition, the Quantile Framework locates a student’s ability to address new mathematical topics. Each of these measures are on a single scale so that the skill demand and student ability can be matched for targeting instruction.”
