Located on the beautiful island of St. Thomas, USVI, our school was established in 1964.  We offer classes starting at age two with our L.A. Casa Toddler Program and continuing through 12th grade.  Our Montessori program includes Primary through Upper Elementary (ages 3 through 12) and is accredited by Association Montessori Internationale (AMI).  Our grades 7 through 12 make up The Peter Gruber International Academy.  We are thrilled to have received authorization from the International Baccalaureate Organization in Geneva as an IB World School - and offer the IB Diploma Programme for 11th & 12th grades and the MYP Programme for 7th through 10th grades. We are one of only 238 schools IN THE WORLD that are authorized to offer both of these programs.   Add to that our Montessori accreditation and we are truly providing a compelling educational opportunity for our students.  All levels at VIMSIA are fully accredited by Middle States Association of Schools.  We are proud of our dual accreditation, but beyond that we also boast a Green Campus on seven lush acres.  Our beautiful campus fosters outdoor activities and provides a wonderful backdrop for our normal school day as well as our many afterschool program offerings.  Our students, staff and parents join to create a loving and caring environment that is diverse and unique in many ways. Like our island, our school is a truly global community.

"The International Baccalaureate (IB) provides rigorous academic programs and assessments and an unwavering commitment to prepare students to be citizens in an international community. IB is to be commended for its visionary approach to promoting a more peaceful world by engaging students, staff and community in a greater awareness of, and appreciation for, differences between and among the peoples of the world."
