Understanding Lexile® Ranges in Vocab Loco

Understanding Lexile® Ranges in Vocab Loco

What Are Lexile® Ranges?

Lexile® measures are widely used to describe the reading difficulty of texts. In Vocab Loco, some vocabulary lists include Lexile Ranges (for example, “Grade 4 — 635L–950L”). These ranges help teachers match vocabulary difficulty to general grade-level reading expectations.

Our Lexile Ranges are approximations, not official Lexile® scores or MetaMetrics-certified measures. They are provided as a guide to help educators align vocabulary instruction with reading comprehension levels commonly associated with each grade.

How Are Lexile Ranges Used in Vocab Loco?

Vocab Loco uses Lexile Ranges to show word list complexity — not to measure student performance.
Teachers can use these ranges to:

• Select grade-appropriate word lists.

• Align vocabulary instruction with reading programs that use Lexile ranges.

• Group students by reading level using comparable ranges.

Why Can’t I “Coordinate Lexile Scores”?

Vocab Loco focuses on vocabulary growth, spelling mastery, and word understanding, not reading comprehension metrics. While you can choose word lists by Lexile Range, Vocab Loco doesn’t assign or track individual Lexile® scores for students.

If you used our legacy program (VocabClass), you may recall direct Lexile coordination tools — those features have now been replaced by flexible grade-based word lists and custom assignment tools in Vocab Loco.

How Lexile Labels Appear in Vocab Loco

You’ll see each word list labeled by grade and range:

• Grade 3 — 415L–760L

• Grade 4 — 635L–950L

• Grade 5 — 770L–1080L

• Grade 6 — 855L–1165L

• Grade 7 — 925L–1235L

• Grade 8 — 985L–1295L

• Grade 9 — 1040L–1350L

Because “Lexile Range” already appears in the category title, individual list names now display only the grade and numeric range for clarity and trademark compliance.
