5/10GreatSchools RatingParent Rating AverageOur grandson has flourished at Flowery school. We are so impressed when he reads us a book in Spanish and the fact that he reads just as well in English is amazing. Have said before that the atmosphere at Flowery is truly a sunny one and we always look forward to a visit when we are in town. This school model is needed everywhere. Hope to be back in the fall this year and am sure we will stop by.Other Review12y ago - Sonoma Valley High School

7/10GreatSchools RatingParent Rating AverageThe community was good but some of the teachers were very bad. There was an AP Biology teacher that wanted to be a friend over getting us ready for the exams. But overall, not a horrible expirience.Parent Review5y ago - Adele Harrison Middle School

4/10GreatSchools RatingParent Rating AverageOur experience at this school could not have been much worse. Leadership practices selective enforcement, is unwilling or worse yet, unable to tackle serious issues between students and doesn’t. Sweeps bullying under the rug, students and parents do not feel they are heard or circled back to or when reporting incidents. Creating a pattern where reporting to teachers or leadership results in little to nothing; thus teaching this age group to not bother to trust in any process in place. Parents kept at a distance and if you dare advocate for your student, you are simply put on their list to avoid. Academics are delivered to a minimum standard with little challenge and or real preparation for anything other then the sub par offer that is Sonoma high. My student floated through academically getting A’s on sub par work. School doesn’t even send correct report cards, issues mis calculated GPA’s and doesn’t correct their mistakes, leaving students scores incorrect and under rewarded and with little accountability or apology; while educators don’t even bother to use the comments section to say a word. This school has more reaction to a student missing school and that CA stipend they don’t receive for an absence then it does to anything else. This is simply a mill to process this age group only and is under serving its students emotionally, educationally and socially across the board.An embarrassing offer for the families of Sonoma.Parent Review3y ago
