What is Spache Readability Formula?
'''Spache Readability Formula''' is one method of finding out how hard a piece of [[write|writing]] is (its [[textual difficulty]]). The method compares [[word]]s in a text to a list of words which are familiar in everyday writing. The words that are not on the list are called ''unfamiliar''. The [[number]] of words per sentence are counted. This number and the percentage of unfamiliar words is put into a [[formula]]. The result is a reading age. Someone of this age should be able to read the text. Spache works best on texts that are for [[child]]ren under the age of eight. the formula; (0.141 * average sentence length)+(0.086 * percentage of difficult words)+0.839 = grade level According to Oleander Solutions ([http://www.oleandersolutions.com]), the revised Spache Formula is: GL = (.121 * ASL) + (.082 *UW) + .659 Where: GL = U.S. grade level ASL = Average sentence length UW = Number of unique unfamiliar words ==Related pages== *[[Flesch-Kincaid Reading Level]] [[Category:Reading]]
