Classes are small (15 students is the class maximum for most) and interactive. There is close and constant communication between teachers, student, and parents. Hillside Summer School also offers a variety of online courses. These are hybrid courses where online learning is paired with traditional in-class time. Students come in once a week to take assessments, work on group assignments or projects, present information, clarity concepts and interact with faculty and other students.
Summer school involves a commitment by both students and parents. Because of the intensive nature of the summer school course, students must be willing to spend considerable out-of-class time on homework, projects and other coursework in order to succeed. For this reason families must not schedule an overlapping vacation or other activities that would result in even brief absences.
