About Your Interview


We interview prospective K-7th grade students to assess developmental and academic readiness. Students who apply for 2nd-7th grades have to come for a morning or afternoon visit.


We interview all K-7 parents at the same time that their student is assessed for developmental and academic readiness. For prospective PK3-PK5 parents, we interview parents while their child is being observed playing with other children. At the interview, we answer your questions and review the school’s expectations for parents.
