One of the top community colleges in the nation is Santa Rosa Junior College. On Niche, in their 2019 rankings, they ranked SRJC as #5 in the best California Community Colleges. It was initially created for students to go right into UC Berkeley after they graduate. Additionally, it has some of the best teachers in the state (many graduating from UC Berkeley, UCLA and Stanford).
It has the highest transfer rate to UC Berkeley in the nation. Also, it has a great STEM program. However, the STEM program is very difficult as the classes there are modeled after UC Berkeley’s. Students who have gone to both Santa Rosa Junior College and UC Berkeley say the STEM classes have about the same level of difficulty. I would think UC Berkeley would be a bit more challenging however. People say Santa Rosa Junior College is the Ivy League of Community Colleges. It even looks like one.
