Learning Begins With Us

MS 51 is a welcoming, diverse, and inclusive school with a community committed to ensuring all children feel supported and successful at this pivotal moment in their lives. Our curriculum, focused on challenging academics, an extensive study of the arts, and social-emotional learning, supports all students while they grow in their knowledge of themselves, one another, and the world. 

First Day of School Procedures

We want all who walk through our doors to feel safe, valued, and capable and to leave here understanding their experiences matter, they have a voice, and that they can use that voice to be aware and productive citizens in an ever-changing world.
