I spent a year and a half at this school before I dropped out because it was such a horrible environment. I was bullied constantly because I was an actual person who cared about the world and other people. A kid who was a friend pushed me in the mud and then blamed it on me. Despite security footage, I was the one blamed because that kid's family made a very generous donation to the school. I was told that I would have to apologize or I would have a permanent black mark on my record. My other friends took the bully's side and shunned me. I had always gotten good grades, was an exemplary student, and it didn't matter because I couldn't bribe off the school. It has been over a year since I left and I am still working through trauma and the fear that I will never belong anywhere. For any parents considering sending their kids there, Don't. If you care at all about your children's mental and physical wellbeing, DO NOT have your kids go here.

I have been at this school for my whole school years; this school defines my childhood. I loved all the teachers and the material that they have taught me.I would recommend this to anyone who wants their kids to enjoy just being a kid. I have had some rough times but I know I could always talk to a teacher there, and you will find trouble anyway, it's just a part of growing up. I highly recommend this school ;)

I attended Riverdale between 1955 and 1961. It was socially and academically challenging. There were troubles fitting in. There was lots of homework. But ultimately, all these things resolved, and the start I got served me well academically from high school through law school. Ultimately, Riverdale's challenges were worth the trouble.
