Why Reading Level Conversion Charts Differ by School District

All Why Reading Level Conversion Charts Differ by School District
Table of Contents

Key Points:

  • Reading level conversion chart creators never ran a joint study to align their scales against each other — their charts are based simply on the grade-level guidance published by each reading leveling system (Kitaboo, 2026).
  • Two published conversion charts can differ in numbers for the same score due to charts’ creators building their system based on comparing grade bands rather than testing the same students on both systems, schools and libraries often posting the chart that came with their assessment program, and state education pages sharing Lexile bands in different forms.
  • Among the actions you can take if your school’s score doesn’t match another source are asking the teacher which system the school uses, asking for the evidence behind the score, and performing a direct reading speed and comprehension check to see a clearer picture.

Your child’s school report card, the library shelf, and a reading app may all show different reading levels — they all can be right, because each may use a different scoring system and often a different chart to compare them. See what a reading level conversion chart shows, why charts may give different numbers for the same score, and what you can do when your child’s reading level doesn’t match across systems.

What a Reading Level Conversion Chart Shows

A reading level equivalency chart (same as a conversion chart) puts scores from different reading systems side by side — the systems include Lexile, Guided Reading Level (GRL), DRA, and AR. Basically, if you take your child’s score in one system, the chart gives you an estimate of where that score falls across other systems. 

Teachers, librarians, reading apps, and book vendors use these charts to match children with level-appropriate books, while parents can use these charts to make sense of a school score report that may list levels from different systems.

Why Two Published Charts Can Show Different Numbers for the Same Score

Two published charts can show different numbers for the same score because nobody tests the same kids on every reading leveling system. Instead, each chart provider just makes their own judgment about the band edges of each system. Schools then usually post whichever chart came with their program. Besides, different US states share Lexile ranges in different ways, which also explains why reading levels differ for the same score.

Charts Are Built by Comparing Grade Bands, Not by Testing the Same Students on Both Systems

According to Kitaboo’s 2026 article, Lexile (MetaMetrics chart), Guided Reading (Fountas and Pinnell), and DRA (Pearson) systems were built separately — no study has tested the same students on all three. Chart makers simply place each system’s grade guidance side by side and decide where each band starts and ends.

For example, Literably’s chart starts Grade 2 DRA at 20, while Brighterly reading level by grade chart starts it at 16/18. Kitaboo ends the Grade 2 Lexile band at 500L, while Brighterly runs to 650L. The charts disagree most in kindergarten and Grade 1 — Lexile gives every very early book the same label, “BR” (Beginning Reader), so it can’t tell a simple pattern book from a slightly harder one, while Guided Reading and DRA split those books into separate levels (A, B, C and 1, 2, 3) to be able to do so.

Why Two Published Charts Can Show Different Numbers for the Same Score

Schools and Libraries Often Post Whichever Chart Came With Their Assessment Program

Greenbrook Elementary, a San Ramon Valley school, titles its page a Guided Reading/Lexile conversion table and credits Rigby Education, Scholastic Lexiles, and a 2000 book on book leveling. Scholastic publishing company, Literably literacy assessment platform, and Fountas and Pinnell conversion chart (balanced literacy framework) each publish their own charts too. So, each school posts whichever program chart it already uses, which can result in a difference in school district reading levels, but this difference doesn’t mean any school’s chart is incorrect.

State Education Pages Share Lexile Bands in Different Forms

Georgia’s Department of Education lists Grade 2 reading level at 420L–650L and gives students a Lexile conversion chart measure with their Georgia Milestones ELA score, while Nevada’s Lexile page provides no grade table — it points families to MetaMetrics tools and suggests books from 100L below to 50L above a student’s measure. Besides, a state test and a teacher’s running record measure different things on different days, so a Lexile chart can disagree with a classroom DRA result without either making a mistake.

What to Do When Your School’s Score Doesn’t Match Another Source

  1. Ask the teacher which system the school uses and treat every other number as a reference point. Use guides to Lexile levels, Guided Reading levels, DRA, and AR to see what each one records.
  2. Look for a named source on any chart you use. Greenbrook credits its sources, and Literably dates its chart — a chart with neither date nor source deserves extra caution.
  3. Ask for the evidence behind the number, like the running record, the test date, or the score report.
  4. Keep one source when tracking reading growth — compare scores from the same system and the same chart across the school year, so a change reflects your child’s real progress and not a difference in charts.
  5. Don’t try to convert Lexile to Guided Reading level or any other chart — the charts cannot do that.
  6. If the numbers still conflict, the Brighterly diagnostic reading test can help check reading speed and comprehension directly — private educators then shape online reading tutoring program around those test results.

Is There One “Correct” Conversion Chart?

No, there’s no correct conversion chart. While you can find plenty of those charts online, they are all approximations, and none of them is official or more correct than the other. Besides, major organizations like MetaMetrics (creators of Lexile) and Fountas & Pinnell (creators of Guided Reading) state that their systems do not align directly, which means they can’t be compared to determine which one is more “correct”.

Conclusion

One reading level conversion table differs from the other one because compilers build each of those tables independently from every publisher’s grade guidance, and schools post whichever chart fits their program. Your child’s reading level is the score from the assessment the school actually uses, read as a range. Every other chart is a helpful, but approximate second opinion.

Frequently Asked Questions

Is There an Official, Universal Conversion Chart for Lexile to DRA?

No, there’s no official or universal chart for DRA to Lexile conversion. MetaMetrics creates and owns the Lexile framework, and Pearson publishes the DRA — neither organization officially endorses or publishes a cross-reference standard that can be used to convert them.

Do All Schools in the Same District Use the Same Reading Level System?

No, all schools in the same district do not necessarily use the same reading level system. While many districts recommend or adopt one standard system (such as Lexile or DRA), individual schools, grade levels, or teachers often use different assessment tools and tracking systems.

Can a DRA Score Be Converted to an Exact Lexile Number?

No, a DRA score cannot be converted into an exact Lexile number, as there’s no universal mathematical formula that links these two systems. The two systems measure different things with different methods — DRA evaluates oral reading fluency, accuracy, error patterns, and comprehension through a teacher-led observation, while Lexile measures semantic difficulty and syntactic complexity of text (or reader comprehension ability) on a psychometric scale.

Which Reading Level Chart Should I Trust If My School Gives Me One and an App Gives Me Another?

To determine which chart to trust, check each chart’s date and named sources, then compare your child’s results over several testing periods instead of relying on one score. If the numbers still pull in different directions, consider a direct skills check through a reading test for a clearer view.
