Free Text Complexity Tool

Pearson’s free Reading Maturity Metric™ (RMM) is the most accurate measure of text complexity. It employs modern language analysis techniques to measure deep characteristics of language and align any text to the new Common Core State Standards.

How It Works

Traditional and current readability formulas rely on only a few, simple superficial measures, such as the average number of words in sentences and how frequently words are encountered in general or educational reading. This new measure utilizes a range of measures of the text structure, syntax, and vocabulary usage including Word Maturity. Word Maturity is a novel application of Latent Semantic Analysis, a widely used mathematical model of human language. Its application to text complexity, the Reading Maturity Metric, simulates how each of thousands of individual words gradually develop their unique meanings by being encountered in paragraphs entwined with already known words that implicitly define the new words.
