St. Croix is a university preparation school for students in grades 6 to 12 with a reputation for being an excellent value encompassed in a very friendly and safe environment.
While the academic standards are high, St. Croix supports its coed students through a full ESL program and with a full time international adviser to assist with the needs of the international students.
Because the school enrollment is 500 students, the school is large enough to offer a wide variety of both curricular offerings and after school activities and still small enough to allow students a chance to participate in activities of their choice.
St. Croix prepares students for some of the best colleges and universities in the United States.
