Understand the word count process. In keyboarding, every five letters, punctuation marks, numbers, symbols and spaces equal one word.
Count the words. Have the student type a passage of at least 400 words and time the exercise. Then, count the number of words completed.
Calculate the GWAM. Divide the total number of words keyed by the number of minutes they were timed. For example, if the student keyed a total of 245 words on a 5 minute timing, divide 245 by 5 to see the resultant GWAM of 49.
