Qualitative Assessment of Text Difficulty 

A Practical Guide for Teachers and Writers

by Jeanne S. Chall 

Jeanne Chall and her three collaborators offer a breakthrough in readability measurement: an easy and straightforward qualitative method for quick and accurate assessment of the reading difficulty of written materials in literature, social studies, and the sciences.

Whereas quantitative readability measures are based only on two or three particular text features, the assessment method here is sensitive to the complete range of variables that differentiate the relative difficulty of written texts.
