Tools to Support Reading & Math
The Lexile scale balances a learner’s comprehension against a text’s difficulty. And the Quantile scale balances a learner’s readiness to learn against skills and concepts. With these scales, we can predict how well a learner will engage with content at any level.

How do I use Lexile and Quantile measures?
These testing organizations and publishers use our measures because they are useful beyond the testing day and outside a publisher’s own leveling system. In fact, any linked test can report learner measures. And any publisher may use content measures to communicate their materials’ difficulty.
In addition to our measures, data in areas from vocabulary to math skills and concepts are offered for truly targeted instruction.
