What Parents Should Know
With an enrollment of 24 students, Seaport Academy is a smaller school where families often find a close-knit community atmosphere. Smaller settings can mean more individual attention from teachers and staff, though they may offer fewer extracurricular options than larger schools.
With a student-teacher ratio of 4.8:1, Seaport Academy offers a notably low ratio compared to the national average. This typically means smaller class sizes and more opportunities for one-on-one interaction between students and teachers.
As a private school, Seaport Academy operates independently from the local public school district. Families considering this school should inquire about tuition costs, financial aid availability, and the admissions process. Private schools are not required to follow the same curriculum standards as public schools, which can be either an advantage or a consideration depending on your priorities.
