As a former student here, I was thriving at this school! There is Greater Ridgewood here! They had other activities here too, from what I've seen. I am class of 2020 and trust me, the ENTIRE fifth grade love this school! (mostly) Only there a few cons for this school. And most of the fifth graders who were here were thriving too! So please, if possible, go to this school! Don't turn it down! :D
