Lethbridge Collegiate Institute (LCI) is a public high school in Lethbridge, Alberta, Canada, operated by Lethbridge School District No. 51 that serves grades nine through twelve. LCI was the first school in Lethbridge designated only for secondary students. It opened at its current location in 1950, but was founded in a smaller, adjacent building in 1928. Since its 1950 opening, several additions and layout changes have been made at the school. In August 2010, Chinook High School opened in West Lethbridge with over 700 students enrolled. Those that entered grade 11 in 2009 at LCI were permitted to complete their graduating year at LCI, but west Lethbridge students are now encouraged to attend the new high school, which was being built in conjunction with a western campus of Catholic Central High School, recreational facilities, and a public library.
