In order to understand how computer software can score your timed writings, you will need to review and understand a number of scoring rules. First, you should remember that only one error can be charged to each dictionary word. And just what is a word? In addition to the letters that spell it, for error scoring a word includes all punctuation marks that are directly attached to it, such as commas, quotation marks, and periods. Also ruled to be a part of the word is the blank space that follows its keying. Following the end of a timing all error words are indicated by a red marking. Thus, all the words that contain a keystroke error are immediately pointed out to the keyboarder. The typewriting practice of having to proofread the copy and circle each of the words possessing a misstroke is no longer employed. In fact, the correct form of each of the marked error words is provided in a column to the right of the entered copy. The problem with proofreading typed copy was that it required a large amount of class time, and a high percentage of errors were not located. However, proofreading, or the ability to locate keystroke errors, is a valuable language arts skill.
