Louisiana State University Laboratory School (U-High) is a laboratory school under Louisiana State University and is one of two laboratory schools in Baton Rouge. The other is Southern University Laboratory School (commonly known as "Southern Lab"), which is operated by Southern University on the north side of the city.
The school was established by the College of Education, now known as the College of Human Sciences and Education, of Louisiana State University and has operated under its auspices for nearly 100 years. This coeducational school exists as an independent system to provide training opportunities for pre- and in-service teachers and to serve as a demonstration and educational research center. Since the school is part of the LSU system, students are required to pay tuition. The school is located on the main campus of Louisiana State University in Baton Rouge, a center for the petrochemical industry and a major deep-water port.
The school was designated a National Blue Ribbon School in 2015 and 2022.[1]
U-High Lab athletics competes in the LHSAA.
