What is a Charter School?
A charter school is a tuition-free independent public school of choice, with the ability to select its own board, staff and curriculum. Charter schools are usually small learning communities with a particular curricular focus. In addition, charter schools must go through a rigorous state application process, as well as obtain an authorizer who will be directly involved in monitoring the school’s academic results and fiscal accountability.
Are there tuition costs?
No. As a public charter school, St Croix Preparatory Academy receives state funding for its operations.
What are class sizes?
Grades K-4 have 30 students per class. In addition, Grades K-4 also have an Educational Assistant in the classroom to address their classroom needs. Grades 5-12 have between 27-32 students per class.
"St. Croix Preparatory Academy will develop each student's academic potential, personal character, and leadership qualities through an academically rigorous and content rich educational program grounded in a classical tradition."
A classical model focuses on providing students with the lifelong educational tools to learn and think for themselves. The classical tradition is grounded in the time-tested methodology of learning called the “Trivium”, which recognizes that critical learning skills must precede critical thinking skills.
The Trivium methodology is organized into the three stages of learning — grammar, logic, and rhetoric — which correspond to the general stages of a student’s cognitive development.
At St. Croix Preparatory Academy, the values of citizenship, courage, honesty, integrity, perseverance, respect, responsibility, compassion, self-control, and service will be identified, modeled and clearly conveyed.
Upper School students are required to document at least 10 hours of community service during their freshman, sophomore, and junior year; and 20 hours of community service is required during a student’s senior year. The community service requirement emphasizes the importance of giving to one’s community.
St. Croix Preparatory Academy views leadership as the ability to first think and reason, then act with integrity and responsibility.
‘Leadership’ is one of the most overused and least understood terms in our society, often conjuring up images of power, success, titles and possessions. By contrast, the founders of St. Croix Preparatory Academy view leadership as the product of education and character development.
The School is based on a classical model of education. A classical model focuses on providing students with the lifelong educational tools to learn and think for themselves. The classical tradition is grounded in the time-tested methodology of learning called the “Trivium”, which recognizes that critical learning skills must precede critical thinking skills. The Trivium methodology is organized into the following three stages corresponding to the general stages of a student’s cognitive development:
There are three phases in the Trivium methodology: Grammar, Logic and Rhetoric. Each stage of the Trivium corresponds to the general stages of a child’s cognitive development as follows:
The first phase of the Trivium is Grammar, which emphasizes the facts and rules of each subject that later learning is built upon. This stage focuses on the accumulation of knowledge and the rules related to each particular subject. The objective of this phase is to provide each child with a strong foundation of subject matter KNOWLEDGE.
Cognitive Skills Developed:
The second phase is Logic, which focuses on the students’ ability to analyze and interact with the knowledge acquired in the Grammar stage. The Logic stage is the phase where understanding is grasped. This corresponds with the child’s curiosity and desire to ask questions. The objective of the Logic phase is UNDERSTANDING.
Cognitive Skills Developed:
The final phase, Rhetoric, trains the student how to express and discuss the subject. Rhetoric is the communication stage, where students defend and refute opinions based on their understanding and knowledge of subject matter. This fits nicely with the students’ affinity for contradiction and argumentation. The objective of the Rhetoric phase is COMMUNICATING.
Cognitive Skills Developed:

St. Croix Preparatory Academy uses a classical, liberal arts curriculum for grades 5-12, modeled after many of the best performing secondary schools in the country (e.g., Tempe Preparatory Academy in Arizona, Ridgeview Classical Academy in Colorado, etc.) It combines formal classes, a classical framework, and Paideia seminars to draw out each student’s inner curiosity and passion. It also asks all students to aim for their highest good in everything they try, and to aspire to mirror the efforts and achievements of outstanding historical personalities. In this environment, high achievement by students will be valued, encouraged, and rewarded.
Why is Latin Taught?
The study of Latin fosters decoding skills that provide students with a solid foundation for reading and writing. Latin enhances students’ vocabulary, increases their understanding of English grammar, improves reading and spelling, encourages precise communication, and becomes the cornerstone for the study of other languages.
