Gateway Charter High School

Gateway Griffin

We Are The Griffins!

Gateway Charter High School (GCHS) is a public high school chartered by the School District of Southwest County to educate students in the District. GCHS empowers families and supports students in grades 9-12 to meet and exceed rigorous academic standards, to promote life-long learning skills, and to advance our belief that parental involvement and partnership in education is critical to student success.

GCHS is accountable for academic results and fiscal practices to our Board (the Southwest Charter Foundation), parents, and students. GCHS is reaching for the high standards established in its charter as evidenced by its A+ grade and graduation rate of 87% in 2007. These achievements are made possible through the support of our management company, Charter Schools USA.

What is a Charter School?

Charter schools are tuition-free public schools of choice, but each charter school is governed independently. Unlike traditional public schools, every charter school must demonstrate success, or it will lose its charter.

CSUSA is one of the largest providers of charter school management services in the nation. CSUSA manages private and municipal charters for grades Pre-K through 12.
