How does Dive In work with high school admissions?

Dive In helps students and families explore the high school options—whether public, private, or charter—that best meet their needs. The program was designed to introduce students and families to rigorous private high schools, like Commonwealth. For students and families interested in private high schools, we help with SSAT preparation and offer two free chances to take the SSAT during their eighth-grade year. We also do mock interviews with families and students, and can help with financial aid applications. Please note that admission to Dive In doesn’t guarantee admissions to Commonwealth.
