Sorry, kids, summer is over. Today, more than 47,000 students walked through the doors of D.C. Public Schools to kick off the 2014-2015 school year. And that number, according to DCPS, is the highest enrollment on the first day of school in D.C. in the past five years.

In a release, DCPS says that to keep up with the increase in students, they’ve hired 300 new teachers for the new school year, along with 24 new librarians, 29 new guidance counselors, 13 new social workers, and six new coaches to work with teachers to support students with disabilities.

“We are going big this year at DCPS – with more students in our schools, longer school days across the city and a continued focus on engaging and supporting our students to strive for their absolute best, I am so excited for what’s to come,” DCPS Chancellor Kaya Henderson said in a statement. “The first day is so much fun, and I want that enthusiasm and that love for school to continue throughout the entire year.”

But while DCPS is seeing an increase in student enrollment, it’s still not quite as heavy as charter school enrollment in D.C. In February of last year, Mayor Vince Gray said that public and charter school enrollment may soon be equal. Traditionally, public school enrollment has trumped charter school enrollment, but in the last decade, DCPS enrollment has steadily dropped as charter school enrollment has risen.

Of course, the increase in student enrollment and the subsequent new hires needed to keep up with the amount of new students isn’t entirely surprising considering the District’s population growth in the last five years. Between just April of 2010 and July of 2013, D.C.’s population grew from 605,125 to 646,449.

But that’s not the only change students will see this year. DCPS says that 25 schools throughout the city will offer a longer school day, “allowing more time for instruction while also paying teachers for their longer work schedule.” All DCPS schools will also offer a world language class, as well as added literacy resources and personnel.

And DCPS can expect that number of students to grow a lot more in the next decade. In December of 2012, the Census Bureau found that there’s a mini-baby boom occurring, with the population adding about 6,000 children under the age of five, particularly in Wards 1 and 2.

With D.C.’s population getting increasingly younger, whiter, and, uh, friskier, DCPS is preparing for the influx of new students to come in the next decade. Their “Capital Commitment” initiative, which aims to improve all District public schools by 2017, will “ensure every student, in every part of the District receives a world-class education that prepares them to succeed after school, in college and in life.”

While the last Nation’s Report Card showed that D.C. students made tremendous growth from 2011 to 2013—outpacing every state except for Tennessee—it also highlighted that there’s still a huge achievement gap between D.C.’s white students and black and hispanic students.
