Achievement First Brooklyn High School is a public charter high school in Brooklyn, NY, which shares best practices with Achievement First Amistad High School, the first high school in the Achievement First network of high-performing public charter schools located in New Haven, CT. One of the best lessons learned from Achievement First Amistad High School, which opened in 2006, is the need for urban high schools explicitly committed to closing the achievement gap. Achievement First Brooklyn High School will ensure that students receive the consistent academic rigor and character development they need to complete the path to college.

Achievement First Brooklyn High School is based on an innovative premise: closing the achievement gap by providing a prep-school quality education to inner-city students. Achievement First Brooklyn High School combines rigorous academics and high expectations with a host of supports, including SAT prep, intensive college counseling, tutoring, explicit character education and a school culture in which it is “cool” to be smart. Key facets of the Achievement First Brooklyn High School program include:

  • Rigorous course of studies for all students: At Achievement First Brooklyn High School, every student is on a college-preparatory track. All students complete a rigorous course of studies focused on core academics, and acceptance to a four-year college or university is a graduation requirement.
  • Personal attention for each student: As a small school, we can better meet the needs of each individual student. Small class sizes, small case loads for college counselors and small advisories enable us to make sure that no student “falls through the cracks.”
  • Focused learning environment: One of the biggest obstacles to learning at many urban high schools is a lack of discipline. At Achievement First Brooklyn High School, our staff works hard to create and maintain a sacred learning environment where all students are focused and engaged and where it is “cool” to be smart.
  • Commitment to robust student life programs: While providing a strong academic foundation will always be our first priority, we also realize that our students need opportunities to have varied experiences, including internships, community service and summer programs. In addition, it is important that our students have a fun and memorable high school experience made possible through the availability of extracurricular activites, awards ceremonies, senior privileges, dances and other popular high school rituals.
