THE EDUCATOR'S WORD FREQUENCY GUIDE is the largest systematic word frequency count ever conducted. Based on over 17,000,000 tokens & 164,000 types, it is nearly 3 times the size of the corpus in the American Heritage WORD FREQUENCY BOOK, which is now over 20 years old. THE EDUCATOR'S WORD FREQUENCY GUIDE exceeds the earlier study not only in number of words, but also in number of samples (60,500) & number of different texts sampled, spanning texts from kindergarten through college. This comprehensiveness & diversity give THE EDUCATOR'S WORD FREQUENCY GUIDE corpus better coverage of actual text use across the grades than does any previously published word frequency study. The guide is comprised of four sections. Technical characteristics are described in the first section, followed by an alphabetical list of words with frequencies of 1 or greater in section 2. This list includes SFI, D, F, U, & frequency by grade-level statistics for each word. Section 3 lists words with frequencies less than 1, & the final section presents the words from the entire corpus in descending order of frequency.
