While most first-time volunteers have no experience teaching prior to their ILP semester, yes, there will be at least one person (your Head Teacher) who has taught with ILP before.

Head Teachers are volunteer peer supervisors that have at least one semester of ILP  teaching experience. Your ILP Head Teacher works with your ILP group — they are there to help lead the group, conduct teaching trainings, and give suggestions for working with the children. They also work with the Local Coordinators and school to help keep things running smoothly. You may also have alumni in your group who are returning to teach for the second or third time.

It’s also good to remember that most locations are familiar with the ILP program. Children who have been in ILP classes for a few semesters typically know what to expect (though they do like to bend the rules to make sure you’re paying attention!). But even if you’re the first semester in a brand new location, you will have a Head Teacher there who’s familiar with the ILP method to help you.
