New Dale-Chall Formula
Published in 1995, the “new” Dale-Chall readability formula uses an updated word list and table-lookup procedure in determining readability scores. Generally considered to be one of the most accurate readability formulas - the new Dale-Chall formula is especially useful in scoring books, pamphlets, news articles... plus a wide variety of everyday reading materials. The New Dale-Chall Formula supports the scoring of materials in either of two modes - quick and approximate, or methodical and precise. You may use either mode - whichever best fits your accuracy requirements and time constraints.
