Guests from outside of ECHS must purchase their tickets online and fill out separate paper permission slips. For this reason, the purchase link for outside guests is different from ECHS students. Outside guests must be high school students and at least 14 years of age. Graduated students may attend, however, they can be no older than 20 years of age in order to participate. Outside guests can find their paper permission slips here. Please print out the permission slips and sign them by hand. ECHS students should bring their outside guest’s completed permission slips when they come to pick up tickets.
