What is the Coleman-Liau Index?

Developed in 1975 by Meri Coleman and T. L Liau, the Coleman-Liau Index is one of the most commonly used readability formulae.

Classic readability tools involve counting the number of syllables per word and per sentence. Yet, the Coleman-Liau Index doesn't count any syllables.

Coleman & Liau argued that techniques designed to estimate the number of syllables lacked accuracy.
