| 12/30/2008 | student | Mattole Triple Junction is not as strictly crazy as most schools, cares about students, small enough to know everyone on a personal level, teachers are pretty cool too! Also you get the benefits of culture through foreign exchange students!! |
| 10/28/2004 | parent | As a parent of a 2004 Mattole Triple Junction graduate, I know that the school staff and teachers contribute so much of their time to give their students an education that compares favorably to that offered in some of the 'richest' school districts in California. This school is rich in caring and individual attention. It also has some of the highest test scores in the state. The library has a great collection of relevant books, and students learn in a comfortable family environment. Even though this school is small and remote, graduates are well prepared for college work. |
