For over 13 years, the New Orleans Center for Science & Math operated as a half day program within the Orleans Parish School system offering specialized instruction in science, math and technology, providing an open door to any interested New Orleans high school student. The post-Katrina public high school situation dictated a new model for SciHigh. In October, 2005, a mere 60 days after Katrina hit the New Orleans levee system, The Advocates for Science & Mathematics Education, Inc. applied for and were granted a Type III charter by the Orleans Parish School Board. Responding to the new environment, including the fact that only 4 other high schools were opened in New Orleans after the storm, the original half-day program became a full-day program offering all subjects required for graduation.
