The Center for Environmental and Natural Sciences (CENS) specialty program at Freedom High School offers a rigorous four-year program of studies designed to include strong laboratory and field investigation components. An enriched and interdisciplinary curriculum helps students gain a greater understanding of the connection between scientific and other academic areas.

The program emphasizes interactive science research and projects that make use of the on-site CENS lab, greenhouse, aquarium, diverse habitats, and wet pond. Students participate in co-curricular and extra curricular activities, including community service, and will become involved with business and community partnerships that enhance their understanding of environmental and natural sciences.

The program of studies includes a sequence of required CENS science courses, pre-AP/AP English and History and Social Studies courses, and a strong mathematics sequence.
