School Reviews

1 10/10/2025

This school has high academic standards likely because of parents who push their kids to perform. However, it is rather poorly run on account of their inability to tamp out bullying and anti-social behavior by students. Kids on the receiving end don't seem to have any recourse, which is a shame for a neighborhood school. They need to have better controls to monitor and contain aggressive behaviour by some kids.

Our family had two nieces, one nephew, and two daughters go through Regnart Elementary School, between twenty-eight years ago and until three years ago. All kids had positive overall experiences, were exposed to caring teachers and excellent academic and social educations. I am sorry to hear that not all have been as fortunate. Based upon our experience, we would choose Regnart again. I suggest to all parents that being involved through the PTA and as classroom volunteers is a fantastic way to get to know other parents, the kids, and the entire Regnart community.
