8/10GreatSchools RatingParent Rating AverageDear Parents,I hope this message finds you well. I wanted to share some serious concerns regarding my experiences at MacArthur Elementary School.Recently, I was physically restrained by a teacher for humming in class. As someone with ADHD, I sometimes struggle to control impulses, especially without medication. I felt that this response was inappropriate and not conducive to a supportive learning environment.Additionally, I had a troubling experience with the food served in the cafeteria. I believe I may have experienced food poisoning after consuming a meal that contained expired items and hair. This raises significant concerns about food safety and hygiene in the school.I hope by bringing these issues to light, we can work together to ensure a safer and more supportive environment for all students.Thank you for your attention.Sincerely, AnonymousOther Review7mo ago - John F Kennedy Middle School

8/10GreatSchools RatingParent Rating AverageAs someone who has gone here, these so far have been 3 of the worst years of my life as an LGBTQ student. I got called slurs in the halls, and the counselors wouldn't do anything about it either. I have gotten hurt here from students, and they didn't care. I feel so bad for the people who aren't "popular" who go here do WHATEVER you can to not go to these middle schools I got water thrown at me in front of the whole school because of bullying the bullying was so bad I would harm myself.Other Review8mo ago - Waltham Sr High School

4/10GreatSchools RatingParent Rating AverageThe new building opened in august 2024 and it has been a great experience in the extensive CTVE offerings. Students are engaged and motivated to attend classes. For the most part, school is everything you expect in an American high school. The AP teachers are wonderful and the early scholar's program with metro west are hands down the best learning opportunities. There are numerous clubs and sports for students to participate if they wish to. The equity score on this site is concerning, but to be expected as our school has many first-generation students with limited and interrupted schooling that can't just equally perform during 'common assessments testing'. Waltham high school produces graduates ready to excel to the level they pursue. We know various Harvard, Princeton, Yale, Umass, NYU, Northeastern, BC, Brandeis, Bentley bound youth- a few sports scholars, and some who go to the trade schools. When you visit the school you get a sense of a mini college campus, with the project-based learning focus, the breakout student spaces offer useful collaborative-social areas. The school can improve as it finds all its potential integrating more corporate community partnerships.Parent Review1y ago
