We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

1. Overall Experience: My time at Haddam-Killingworth High School was quite positive. The teachers were dedicated and supportive, and I felt like I had access to a lot of resources to help me succeed. 2. Experience: I appreciated the sense of community and the opportunities for involvement in various clubs and sports. It was great to be part of such a close-knit environment. 3. Best and Worst Parts: The best part was definitely the relationships I built with my peers and teachers. However, I found that sometimes the workload could be overwhelming, especially during exam periods. 4. Changes: I would love to see more mental health resources and support for students, as well as more flexible options for coursework to.

I moved to this school freshmen year from a school I did not feel happy at. When I came here I instantly felt welcomed and I actually had to start working hard for good grades. At my other school I would just slack off and not care because that's what everyone did. But here all the students and staff motivated me to be my best self and try my best.
