What Makes Us Special

The focus at Gridley Middle School is on individual student academic achievement, with teachers and staff teaming up to make sure students can do their best. The team approach helps students feel engaged and connected to their school and their learning. The school’s mission is student excellence by concentrating on community, integrity and commitment.

Using an integrated curriculum, students are encouraged to push themselves by getting involved in a nationally known Virtual Reality Lab, and a STEM (Science, Technology, Engineering and Math) program. Honors classes are offered in all core subjects, including Algebra for eighth graders.

Yet, it’s not just all science and math at Gridley. The school offers a Fine Arts program that comprises band, guitar, and orchestra for all grades. Keeping students busy all day also translates into afterschool programs. Gridley has a wide variety of extracurricular activities for all interests such as a garden and chicken coop club, book club, chess club and interscholastic sports.
