FRYE READABILITY SCALE or GRAPH by Jamestown Publishers 1978. MINT CONDITION. Includes Directions and Plastic Sleeve. It works like a slide rule to determine the grade level something is written on - all the way from a 1st grade level to a college level. It says on it Copyright 1978 by Edward B. Fry. Edward Fry worked as a Fullbright scholar in the 1960s in Uganda. While trying to help teachers teach English as a second language, he created one of the most popular readability tests, one that uses a graph. Fry returned to the U.S. to become the director of the Reading Center of Rutgers University and a renowned authority on helping children learn to read. Fry"s original scale determined the difficulty of a text through high school. It was validated with comprehension scores of primary and secondary school materials and by correlations with other formulas. In 1969, Fry extended the graph to primary levels. In 1977, he extended it through the college years. By plotting the average number of sentences and syllables in samples of 100 words, you get a grade-level score—the reading ability required to read the text. This device is copyrighted 1978.
