Lexile® Framework for Oral Reading

The Lexile Framework for Oral Reading is a scientific approach for measuring both students' oral reading ability and the oral reading difficulty for text (or oral readability). Oral reading ability is conceptualized as a latent trait that influences a student’s chance of success in reading professionally edited text aloud. Oral readability is a quantitative feature that represents the difficulty of reading a text aloud.

Knowing the Lexile oral reading measure of a student and the Lexile oral readability measure of a text can be used to predict how the text matches the student’s ability. This helps identify whether a text may be too easy, too difficult, or just right for the student to read aloud.

MetaMetrics provides an API service that analyzes audio recordings of students’ oral reading, and then returns a Lexile measure, as well as other diagnostic information. How it works:
  1. The student reads a passage aloud for about a minute or even less for younger students. The student’s reading is captured by an audio device determined by the assessment developer.
  2. Audio files are sent via API to MetaMetrics where they are analyzed. API is powered by Carnegie Speech that uses state-of-the-art speech recognition.
  3. A student's oral reading measure, along with a diagnostic profile and personalized qualitative feedback, are returned via API in 1-2 minutes. Diagnostics take into account the complexity and readability of the text. 

Lexile oral reading measures and Lexile oral readability measures are expressed as numeric measures followed by an “L” (for example, 350L) and are placed on the Lexile scale. Measures range from below 0L for beginning readers and materials to above 1000L for advanced readers and materials.

Benefits of the framework:
  • Accurately evaluate students’ abilities. Lexile oral reading measures provide consistent results because we take into account both the oral reading level of the student and the readability of the text.

  • Evaluate students’ oral reading abilities efficiently and removes subjectivity. Requires no manual scoring from educators.

  • Track changes in proficiency. Highly sensitive Lexile oral reading measures easily track growth in beginning readers and can be used for frequent progress monitoring – even weekly!

  • Activate reading & speaking. Tests linked to the Lexile Framework for Oral Reading can offer qualitative feedback with a list of words to practice based on reading performance. Research shows that repeated practice of reading aloud improves fluency.

  • Get a more detailed student literacy picture. Lexile oral reading measures can be compared with other student Lexile results, such as the Lexile reading measures for more diagnostic information about students’ abilities.
