The Coh-Metrix Common Core Text Ease and Readability Assessor (T.E.R.A.) provides measures of text “easability” and readability. Most current readability measures are based exclusively on two features of text: the difficulty of sentences and the familiarity of words. Coh-Metrix  T.E.R.A. is very different. It provides component profiles of text easability on five different dimensions: narrativity, syntactic simplicity, word concreteness, referential cohesion, and deep cohesion.

T.E.R.A. allows educators to see a profile analysis of a text by either entering their own short passage or selecting one from an existing library of Common Core Exemplars. All text profiles include percentile comparisons to other texts (along the five component dimensions) and a description of the text properties.
