  • In order to encourage iO’s philosophy of commitment to a group and an ensemble. students are allowed to miss no more than two classes in each 8 week session. (You may make up a class, but make-ups will still count as an absence.) If a student misses more than 2 classes they are required to repeat the level.
  • Tuition is non refundable. If you cannot attend the class you registered for, we can roll your tuition to be used during another session as long as you contact the Training Center 24 hours prior to the class beginning. If you reach out after that, we cannot roll your tuition.
  • Participation in or completion of classes does not guarantee placement on an iO Harold Team.
  • The iO Theater reserves the right to postpone or cancel a class if they do not reach a minimum number of students.
  • Our instructors are working actors/improvisers. While we don’t anticipate having to change the instructor after registration ends, please be aware that this may happen from time to time.
