Welcome to Lexington Trails Middle School. LTMS was established in August of 1995 when the De Soto School District went from one junior high school to two middle schools–one on the east side of the district and LTMS on the west side of the district. For the first three years, the middle schools included 5th–8th grade students and the initial LTMS enrollment was about 320 students. Enrollment grew at LTMS to approximately 550 students before the district opened its third middle school in 2007. Currently the LTMS enrollment is about 390 and is trending upward.
