10/10GreatSchools RatingParent Rating AverageAs a parent of a student at Brooklyn Technical High School, I can say with confidence that this school has been a fantastic choice for our family. Like many parents, I had initial concerns because of the school’s size—it’s one of the largest high schools in the country, with a massive building and thousands of students. But we quickly learned that size does not mean students get lost. On the contrary, Brooklyn Tech is a place where motivated, hardworking kids can really shine.My child has found both academic and extracurricular opportunities that fit their interests perfectly. There are so many majors, electives, and clubs that every student can find a niche and a supportive peer group. The rigor is demanding, but it prepares students incredibly well for college and beyond. I’ve seen my child grow in confidence, independence, and intellectual curiosity, which has been so rewarding.Another strength is the way the school communicates with families. Brooklyn Tech does an outstanding job keeping parents informed through daily communications. I never feel out of the loop. Teachers and administrators are also very accessible and responsive whenever I’ve had a question or concern. Even though the school is large, I’ve always felt that faculty genuinely care about their students and want to see them succeed.One area I especially want to highlight is safety. Brooklyn Tech feels very secure, even though it does not rely on full-time metal detectors like many other NYC public schools. The administration and staff clearly take safety seriously, and the systems in place—combined with the orderly, respectful environment among the students—create a school culture where both kids and parents can feel at ease.In short, Brooklyn Technical High School is not for students who want to coast—it’s a place for motivated young people to challenge themselves, discover their strengths, and prepare for the future. With excellent academics, strong communication with families, caring faculty, and a safe environment, it’s one of the best educational opportunities available in New York City.I couldn’t be happier with our experience so far, and I wholeheartedly give Brooklyn Tech 5 out of 5 stars.Parent Review10mo ago - Ps 282 Park Slope
