We came into office with a clear mission: to build a safer, more affordable city. And our initiatives for our students continue to deliver on that promise.

As the administration running the largest school district in the nation, we are committed to giving our children a first-class education. And a crucial part of a great education is having access to excellent facilities, thoughtful curricula, and equitable early childhood education.

We want our students to learn in modern and flexible spaces, with state-of-the-art technology and healthy, green construction, and we want them to have access to science labs, music rooms, gyms, auditoriums, libraries, and all the services they need. That is why, for the upcoming school year, we have opened 24 new school buildings across the five boroughs, which will add 11,000 new student seats — the most K-12 seats we have added in a single year since 2003. This is in addition to the 23,000 seats already added during our administration. And it means that we can close all but 24 outdated trailer classrooms from our schools.

That brings the total number of students who received an early childhood offer to over 53,000 — more than three times the number who received an offer just five years ago. And over the past school year, we had 150,000 students enrolled in early childhood education across our system — a record high.

I understand the importance of early childhood education for success in school, college, and life. My own mother struggled balancing work and taking care of me and my siblings. Too many mothers across the city still face similar challenges.

I know that access to affordable…
