Lake Weir High School was established in 1955 as a consolidation of Weirsdale and Summerfield High Schools on a hill overlooking Lake Weir with a student body of about 300 students in grades 7 through 12. Mr. Leo Armstrong, former principal of Weirsdale High School was the first principal. The school served students coming from elementary schools at Belleview, Florida, Summerfield, Florida and Weirsdale, Florida that served the communities of Belleview, Candler, East Lake Weir, Ocklawaha, Pedro, Summerfield, Sunset Harbor, and Weirsdale. The first class of 1956 graduated 33. In 1967, Marion County changed to the elementary, middle and high school organization and the school changed to grades 9 through 12. In August, 1975, a new Lake Weir High School was constructed on Maricamp Road in Candler with a student body in excess of 1200 students, which grew to 2500 by 1993. The former Lake Weir High School campus then became home to Lake Weir Middle School, which serves grades 6 through 8.
