California (North)

Northern California holds a separate competition from Southern California because of distance issues. It has a medium amount of membership compared to other states. There are 7 regions in Northern California all with about 30 teams per division. All regions hold both B and C competitions.

History
A small bit of history but certainly not all of it.

B Division
There have been quite a few close NorCal finals competitions over the years, some decided by just a point or 2. The nearly 30 years of Sci Oly history in NorCal have been dominated by 2 schools, Churchill and Arden. Together, these 2 schools account for most of the NorCal 1st place finishes. Interestingly, these 2 schools or both in Sacramento, both in the San Juan School District and are located just a few miles from each other. Other schools that have won the NorCal title are Elkhorn from Lodi and Carnegie MS in Sacramento. John Barrett MS (also a San Juan USD school) has consistently been in the top 5 or so places for many years prior to 2011. In recent years, the number of competing teams grew from 16 in 2008 to 18 in 2009 to 24 in 2011, and a few San Francisco Bay Area schools from Fremont (Hopkins, Mission Valley) and Cupertino (Kennedy) have finished in the top 3 at NorCal finals. In the 2014 tournament, 4 out of 5 of the top 5 schools were from the San Francisco Bay Area.

C Division
Mira Loma High School has dominated the C Division in recent years but has started to feel some heat from Bay Area schools like Mission San Jose High School, Palo Alto High School and Henry Gunn High School. In 2013, Palo Alto managed to defeat Mira Loma by one point.
