This school was amazing for me. There was so much thought out into making the learning interactive (innumerable simulations, challenging projects, opportunities for group work). I am in high school and I still think that I got my best history education at PS 321. I also acceled at math and was got to do advanced work, which was exceptional at such a young age. This school prepared me effectively for middle school and helped me develop positive work/study habits. Thank you PS 321!!

This school is totally overrated. The staff is rude, the needs of individual kids and families are ignored, and unless your child is perfectly self-motivated, always well-behaving, and not distracted by everything happening a very crowded classroom, he/she isn't a good fit for the school.
