Thirty two fourth level students in the Department of Foreign Languages at King Faisal University have participated in the study. They are 22-24 years old. All the subjects of the study were Saudi female college students enrolled in an advanced course, Language Testing, and most of them have successfully passed all the courses of the English program and are left with only one course, Teaching Practice. It is important to mention here that the students have attended an Error Analysis course where they were taught how to identify, classify and describe written and verbal errors in English made by second.
