    Horrible. The administration is oppressive and the handful of quality teachers are locked into the policies of "common core standards." Art physical education music and computer literacy are advertised as backbones of the curriculum but in reality they hold no value to the current principal. What does hold value is the annual STAR test which could help to remove the stigma of the school's "program improvement" classification. And as our children were driven to achieve high test scores they were bullied on the playground with no repercussions for their aggresors. There is almost no parent participation and the PTA has dwindled to faculty and members of the board of trustees. In fact the last three PTA presidents transferred their children to other schools.

    Cinnabar Elementary School was Petaluma's first elementary school founded in 1859. It celebrated its 150 year anniversary in 2010 with a large festival.

    Cinnabar is located in a country setting that offers oportunities for 'outdoor' classroom education. The teachers truly care about the children and offer support programs before and after school. The comprehensive technology program placed my daughter above her peers when she moved on to junior high school. The student population is rich because of its diversity. Some programs have been cut recently due to reduced state funding. Parents and staff are engaged in fundraising and grant writing to restore these programs and invest in additional ones. I think the true testament to the success of the school is that former students come back as adults to teach enroll their children or just enjoy the traditions and community activites at Cinnabar.

    Cinnabar has gone through administrative changes during the past few years. Now with a new administrator and a dynamic teaching staff this school ranked the highest in a positive API movement the Sonoma County Schools. With Sonoma County Schools ranking the highest in the state of California last year in terms of positive API movement and test improvements Cinnabar ranks as one of the best public schools in California.

    We have only gone through kindergarten so far but my child loved school until this past year. The teacher he had did not focus enough on reading skills. She disciplined him for minor infractions even saving 'time outs' for the next day. He was horrified to go back for 1st grade (which he has) for fear of running into this teacher. He did run into her and she did not even say hello. My son is sensitive and caring a bit hyper I agree but not rude or extremely disruptive. I hope this year is better or I will remove him and put him in private school.

    This is the first year for our principal he is a great man and has a lot of good proyects in mind. He is working hard. I love the teachers in general they are well prepare and with parents involvent we hit a lot of goals. We were having a hard time with the administration in the past which was not so good for our school but we kept confidence in the teachers and the curriculum. Now with Mr. Ecker things look like they are going in the good track.

    This school has been a disappointment. They are on their third principal in the 4 yrs we have attneded. They used to have the reputation of being an elite public school that really cared about the students. Now as parents we feel we are knocking our heads against the wall trying to get anything done for our children. They have begun to cater to the low income families and left the other children to excel along at the medium instead of challenging or helping the ones that need it.
