NAGreatSchools RatingParent Rating AverageMy son started Kindergarten at KCS this year and so far it has been a great experience. They are very organized and the teacher-parent communication is very good. My anxiety about my son starting school (with no pre-school) quickly went away after attending their parent meeting and open house. I may change my review later, but right now this appears to be a great school.Parent Review9y ago - Killingly High School

4/10GreatSchools RatingParent Rating AverageOverall a terrible public school the only part that is redeemable is the agricultural program. The rest of the school is a waste of money and time. Also rejected a federal grant for mental health for students TWICE ( majority of students wanted it and they still rejected it).Other Review2y ago - Killingly Intermediate School

4/10GreatSchools RatingParent Rating AverageTHIS SCHOOL IS HORRIBLE I HATE IT the work BORING OVERUSED STRECHED OUT FOR MONTHS the people like FIVE people are good people everybody else i either dont know or dont acknowledge the rest just have beef with me for pretty much no reason the restrictions HORRENDUS theres like FOUR usable sites and the teachers have the option to just disable/block them and since theres so little sites we cant do much during free time now the rules? LOL theres so many unneeded rules like no hoods and no fighting back i could literary get jumped by 6 people and still get detention "for punching someone" WHAT DID YOU WANT ME TO DO JUST TAKE IT the thing is THIS ACTUALLY HAPPENED IN 5TH GRADE and they try to hide the impending doom by calling it "in school suspension" id much rather be suspended normally and go home than sit at a desk with little to nothing to do besides work and if theres no work to do? you just sit there but oh i need the bathroom "you know the rules 1 break per 2 hours unless medically necessary" ok i get the medically necessary but they limit you to 3 minutes for each break if you go past the limit you get yelled at so basically this school sucks and can have very unfair momentsStudent Review2mo ago - Killingly Memorial School

7/10GreatSchools RatingParent Rating AverageThe teachers and staff went out of their way to make sure that my child was ok during a very stressful time for her. She is excited to go to school and learn new things. The school still provides arts programs that many schools have let fall by the wayside.Other Review9y ago
