International Students

St. Thomas Aquinas High School has been welcoming international students from all over the world for more than ten years! When our students bring their culture to campus, it creates learning opportunities for all of us. Through our extensive host family network, we ensure students are well-looked-after both in their education and their home life. Students may attend for one semester, one year, or up to four years. We are so excited to be part of your journey!
