The California Academy of Mathematics and Science (CAMS) is a public magnet high school in Carson, California, United States focusing on science and mathematics. Its California API test scores are third-highest in the state.

Located on the campus of California State University, Dominguez Hills, CAMS shares many facilities with the university, including the gymnasium, the student union, the tennis courts, the pool, the indoor velodrome track, the library and many of the parking lots. It is a National “No Child Left Behind” Blue Ribbon (2011) and California Distinguished school. The No Child Left Behind blue ribbon was only presented to 32 public schools nationwide. Newsweek states in its top 1200 High Schools in the USA, CAMS is in the top 4% taking number 281 in 2006.

In the December 2007, Newsweek released the results of a two year study to determine the 100 best High Schools in the United States of America. Out of the 18,000+ schools reviewed, CAMS made it into the top 100 as number 21. As of January 2008, CAMS moved up in ranking to the twentieth best high school in the nation. In California is rank 3rd in the State.

Unlike similar schools such as the Illinois Mathematics and Science Academy and the North Carolina School of Science and Mathematics, CAMS is non-residential, drawing its students solely from most of Long Beach, portions of Los Angeles, and some cities of the South Bay region. Students are admitted only as freshmen, after applications and interview processes. In the past, applicants from different grade levels were allowed to apply and be accepted, but due to the strict, demanding curriculum at CAMS, the school felt incomers from other grade levels would be unable to keep up with the rest of the students, as they would be unaccustomed to such a curriculum.
