The Scoring of the TOEFL is different for each Section, Question, & Task. For the Reading & Listening Sections of The Exam — your answers will be scored automatically. But for The Speaking & Writing Sections — your answers will be scored by actual humans who are trained & certified in the criteria for the scoring of these answers.
(Not Actual Certified TOEFL Judges or Scores)
One other thing that makes the TOEFL Exam unique is that: Since there are so many thousands of answers that need to be scored every week — just to ensure that the judges are scoring your answers correctly — there is also a second line of judges that makes sure that your answers are scored properly. (At least, that is what we are told.)
Your scores will be available on-line approximately 10 days after The Exam, and the hard-copy of your scores are mailed to The Institution that you selected upon registration, approximately 2 weeks after The Exam. However — the actual delivery of your scores is subject to the competency of the mailing service in each country.
