School Notes

  • Thomas Jefferson School (TJ) offers an unparalleled college-preparatory curriculum in a close-knit, supportive academic community.  For nearly 70 years TJ`s liberal arts approach has been a launching pad for college and professional success.  College preparation is our speciality: all of our graduates move on to four-year colleges and universities across the nation and abroad.  Average SAT scores consistently position TJ among the world`s top boarding schools.  With a daily schedule of concise morning classes and a student teacher ratio of 7:1, students enjoy focused individual attention with faculty, advisors and staff.  Students develop their academic talents as well as their autonomy.  Most Junior students take two AP courses while Seniors take all AP coursework in their final year.  Day students share dorm space on a picturesque 20 acre campus with boarding students from 26 St. Louis area zip codes, eight states and 11 countries.  Students live and learn amidst faculty members and resident assistants in cottages throughout the grounds.  The Charles Merrill building serves as the hub of activity housing classrooms and the dining room.  Additional campus facilities offer access to athletics and the fine arts.  Five-day boarding for regional families is a popular option. Nearly 40% of TJ`s families receive financial assistance.  As a current TJ student has said "TJ is more than a school.  TJ has given me my voice."
