A Conversion Chart For Reading Level Measurement Tools
by TeachThought Staff
If you’ve used AR (Accelerated Reader) as a reading motivation tool to set goals and track progress, you’re undoubtedly aware of its ability to assess general reading levels as well.
The problem is, measuring reading level is really outside of its sweet spot as a literacy tool, with better resources available from DRA, DIBELS, Lexile, Reading Recovery, and Rigby, among others. There is also the issue of availability, with most schools only using one or two of these tools, primarily in early elementary school. But what happens if you need to convert a general level from one program to another?
1. Lexile Framework for Reading

Cons: Doesn’t account for background knowledge or interest
Best for: Grades 2+, especially when used with adaptive assessments
2. Fountas & Pinnell (F&P)
