Saint Paul Preparatory School

St. Paul Preparatory School, formerly known as Nacel International School, is a private college school in Saint Paul, Minnesota, United States. It is also a part of the Nacel International School System. Founded in 2003 by US-based student exchange organization Nacel Open Door, it recruits students from more than 50 countries worldwide. All international students are placed in host families, where they will live for five to ten month periods while the school is in session.

The enrollment at St. Paul Preparatory School resides from more than 50 countries.

Host families from the metropolitan Twin Cities provide housing for the international students who attend the school. These host families provide shelter, food, and transportation while supporting the study habits of the students and offering an understanding of the American way of life. Students are provided an unlimited metro/bus pass to commute to and from school and visit local attractions such as the Mall of America.

In 2014, St. Paul Preparatory School founded three diploma programs in STEM, Visual Arts, and International Business.

The 'Visual Arts Program' diploma includes a rigorous product oriented portfolio that students develop for public presentation and sale. Students produce artistic creations derived from current inspirational motivation for competition, public display, and commercial marketing.

The 'International Business Program' diploma provides the skills and knowledge necessary to understand, develop, and discuss economic concepts from a micro and macro level. In depth finance concepts of managing and operating a business, as well as hands-on learning through internship based opportunities, provide an exciting and interesting first hand view of the capitalist system.

In 2015, a fourth diploma program was added. The 'Global Leadership Program' combines the communication skills needed for oral argument, speech communications, and problem-solving skills to emphasize leadership and issue-oriented critical thinking.

The school is organized around the diploma programs that provide a focus for the education of all students. Many students attend the school for one year and not able to participate in the diploma programs due to graduation requirements.
