NWEA Lexile and Quantile Measures

Question 1

Which MAP Growth test provides a Lexile measure and a Lexile range?

Accepted Answer

Reading

Answer

Lexile measures describe reading ability and text complexity, so they are reported with MAP Growth Reading results. Math results use Quantile measures instead.

Question 2

Which measure does MAP Growth Math report to connect a student's score to math skills and concepts?

Accepted Answer

Quantile measure

Answer

Quantile measures place a student's math ability and math skills on a common scale. They are the math counterpart to Lexile measures in reading.

Question 3

A teacher wants to select books that are challenging but still manageable for a student. Which MAP Growth data point is most useful?

Accepted Answer

The student's Lexile range

Answer

The Lexile range gives a span of text complexity suited to the reader. It is meant for choosing appropriately challenging texts.

Question 4

How is a Lexile measure on a MAP Growth report derived?

Accepted Answer

It is computed from the student's RIT score using a linking relationship

Answer

NWEA reports Lexile measures by converting the student's Reading RIT score through a linking relationship. No separate test is given.

Question 5

Why should a Lexile measure NOT be used as the only criterion for choosing a book for a student?

Accepted Answer

Lexile reflects text complexity only, not content, theme, or student interest and maturity

Answer

Lexile quantifies text complexity (sentence length and word frequency). It does not capture content appropriateness, theme, or interest, so teachers should also use professional judgment.
