Hillsboro Parent Preschool is a non-profit cooperative preschool for 3-, 4-, and 5-year-olds. In 1978, after many months of planning by a group of parents, HPP was established. Our school is geared toward parents who want to be involved in their children's first educational experience. Hillsboro Parent Preschool is a non-denominational, anti-bias organization. We currently offer two classes and employ one teacher who is assisted by three parents in each session.
