What’s my child’s Lexile range?
Most parents only get a Lexile number from a school MAP test once a year. This is the at-home version: a short adaptive reading check that estimates the same range — and shows you the math behind every point.
Discover books that map to your child’s reading level and interests.
A short adaptive reading check. Each answer makes the next passage harder or easier until we land on a Lexile range — the same measure NWEA MAP reports.
Whose reading check is this? (optional — keeps a separate history per kid)
What grade are they in? (optional — it just sets the starting point)
What are they into? (optional — we’ll match the passages and books to it)
How we estimate Lexile reading range
The test adapts to every answer.
We start near your child’s grade level and use a staircase: a correct answer serves a harder question, a miss serves an easier one — mixing reading comprehension, vocabulary, and language items the way MAP does. After ten to sixteen questions the answers bracket the level where comprehension sits around 75% — the same comprehension target the Lexile Framework is built on.
Each passage is calibrated, not guessed.
Every passage is original and tuned to a target difficulty using the public Lexile Analyzer method — difficulty rises with longer sentences and rarer words. The “show your work” panel on your result lists each passage’s calibrated difficulty and why it lands there.
A Lexile is what MAP reports, too.
NWEA’s MAP Growth Reading report outputs a Lexile range alongside its RIT score, so once we have a Lexile we can show the approximate RIT you’d land on. We treat that crosswalk as an estimate and link the linking study below.
