Lexile Codes

These codes help determine developmental approriateness, not jst a Lexile score for text.

AD: Adult directed (Picture boks to read aloud)

NC: Non-conforming (Doesnot match interest level)

HL: High-interest, Low-readability (Reluctant teens)

IG Illustrated Guide (Indenpendent pieces like encyclopedias)

GN: Graphic novel (Speech bubbles)

BR Beginning Reading (Emergent reader)

NP  Non prose (Poems, plays, songs, alphabet books)

Readability and Common Core Standards

Basic Readability

Reading Ability  can vary from type of text, vary from day to day, vary within a text.

The average teacher reads at a 1400 Lexile.

Lexiles are the current measure of readability often the text and the reading ability of the person. For the first time, this measure claims a correlation between the two.

Readability formulas are based on word familiarity (semantic) measures by word frequency an/or word length and sentence complexity (synthatic) sentence length. It is smeant to predict text comprehensibility and reading difficulty.

What is Readability?

Readability formulas are based on sentence length, syllabication, and word counts. they are typically done by computers with some formulas with more details than others.
