Niche recently released its 2019 ranking of the best public high schools in America, based on an analysis of key statistics and survey responses from parents and students. Ranking factors included teacher quality, state test scores, graduation rates, college readiness, SAT/ACT scores, and high school ratings.

As a parent, you may fear that you can’t give your child the best because you can’t afford a private school education. This list of public high schools demonstrates that private schools are not the only institutions to offer a quality education. Becoming a high-performing school often takes years of hard work. There is no one thing a school can do to ensure students perform highly. A clear and shared focus is one factor – everyone knows what they want to accomplish and why.

Academic performance and exam scores are good indicators of how well a school is performing, but there are other factors, too. Parents want to send their children to schools that produce well-rounded students who will succeed in the real world after school. The student-teacher ratio is another important factor because many studies show that students receive more attention in small classes, and their test scores improve as a result. The following 30 public schools can be proud of what they have achieved.
