|GRAPH FOR ESTIMATING READABILITY - EXTENDED
RUTGERS UNIVERSITY READING CENTER
NEW BRUNSWICK, NY 08904
DIRECTIONS: Randomly select three 100 word passages from a book or an article. Plot
average number of syllables and average number of sentences per 100 words on graph to
determine the grad level of the material. Choose more passages per book if great
variability is observed and conclude that the book has uneven readability. Few books will
fall in gray area but whey they do, grade level scores are invalid.
Count proper nouns, numerals, and initializations as words. Count a syllable for each
symbol. For example, "2012" is 1 word 3 syllables, and "AFT" is 1 word and 3 syllables.
EXAMPLE: 1st hundred words 124 6.6
2nd hundred words 141 5.5
3rd hundred words 158 6.8
AVERAGE 141 6.3
READABILITY 7TH GRADE (PLOT 141 AND 6.3 ON GRAPH ABOVE)
