In 1st grade, a class community of students is formed with a main lesson teacher. These students stay together as a class throughout their OCS experience and graduate together as 8th graders. Their teacher stays with them, “looping” for multiple grades with the class. Typically, a teacher stays with a class for 3-5 years, such as from 1st-5th grade. When appropriate for teacher and his/her class, a teacher may loop all the way from 1st to 8th grade with a class.
