School Notes

  • TJ is an internationally respected, coed day and boarding school for grades 712. TJ is located on a beautiful 20-acre campus in Sunset Hills, where students come from twenty eight St. Louis zip codes, five states, and seven countries to connect with others who share the same passion for learning. No matter their background, TJ students share energy, independence, intellectual curiosity, and a commitment to preparing for college. Since 1946, TJ has been a greenhouse for true intellectual growth. The classical liberal arts curriculum emphasizes depth in a college preparatory core, and as a result, students` SAT scores consistently position TJ among the world`s top boarding and day schools. TJ`s program emphasizes responsibility for oneself and for the community, and holds students to high expectations in every area of school life. College preparation is TJ`s specialty. Students receive an unparalleled academic foundation- by senior year, all subjects are studied at the AP level-and a daily schedule encourages the development of personal independence. All graduates move on to four-year colleges and universities across the nation and abroad, where they settle in with confidence and ease.
