  1. Radnor Senior High School

    • Radnor Township School District, PA
    • 9-12
    • 102
    1 Best Public High Schools in Delaware County

    Alum: Throughout my time at Radnor High School, I really enjoyed learning with a great community. My classes were taught with teachers who have great enthusiasm and much caring towards their students’ wellbeings. The counselors do a great job guiding students and making sure they are on track with what the future lies ahead of them. The music and arts programs are very strong as well as the sports program. Something that I would like to see change perhaps is the increase in all sorts of awareness programs or assemblies. While it’s hard to schedule these types of things into a school schedule, it may be beneficial to the students if these awareness programs occurred more often than they do now.

    Senior: Strath Haven has something to offer all students. Overall, the teachers are very good and are interested in what the students are involved in outside of their classroom. The band, sports teams, theater programs and the general arts programs are very strong. When I talked to friends who are in college, they say that Strath Haven prepared them well for college!

    3 Best Public High Schools in Delaware County

    Senior: Overall a pretty positive experience! No school will ever be perfect but I have definitely had more positive experiences rather than negative ones, and it really has made the person I am today. From the teachers I have grown close to, the friends I have made, the classes I have learned to love, the classes I have pushed through even though they may have been difficult or not interesting, and the abundant amount of activities I have gotten myself involved in, I have such great things to say about the school I am sad to be leaving in June. When things have been rough, all of the students work together to keep on making it a fantastic place and I would not have ever wished to go anywhere else for my 4 years of high school.

    Grier School

    • Private School
    • Birmingham, PA
    • 7-12
    • 57

    Senior: As an all girls boarding school, Grier boosted a positive studying environment and encouraged its students to strive for both rigorous academics and varied extracurriculars as well. I particularly enjoyed the all-girls atmosphere, as it encouraged my participation and gave me a sense of community unparallelled by any co-ed school.

    5 Best Public High Schools in Delaware County

    Alum: I think that the High School had great teachers especially in the science and math department! There are also plenty of wonderful teachers in other departments as well! There should be more encouragement and congratulations for the academic teams for their hard work. If you are an athlete, prepare for some hardcore competition. The 10-12 guidance counselors didn't do their job they way they should have. I wish they got the students started with college opportunities earlier. They should encourage the students to strive higher than just the "okay" colleges and universities that are in the area. The students should be helped and encouraged to take classes at colleges during high school even during the summer! There are plenty of things Penncrest needs to improve on, especially the guidance department, but this school got me ready for college and I am happy to say I am a Penncrest alum!

    6 Best Public High Schools in Delaware County

    Alum: Springfield High School gave me the flexibility to explore my interests and to see what I wanted to major in during college. By encouraging students to take classes in a wide variety of areas and including higher-level classes like APs, my education was well rounded. In addition, students were encouraged to get involved in the clubs and organizations offered. While this may have lead to many of us being over-involved, I wouldn't have changed a thing. Springfield gave me the opportunity to get in touch with different people through those clubs and classes. Springfield prepared me to succeed in college.

    Junior: Most teachers really try to connect with their students and make sure that they understand the topics and could connect them to situations outside of school. The teachers and staff truly care about the wellbeing of their students and many of the students are extremely welcoming and friendly, making friend groups easy to fit into. Many of the honors and advanced placement classes are challenging and lots of hard work but well worth it in the end.

    Senior: At Upper Darby Senior High School, there are many opportunities that are offered that many students should take advantage of. Because of its size, the public school has many students from different cultures and ethnicity. Many students are very prideful for who they are and other students learn and respect others' preferences. Based on the student population, there are a variety of extracurricular activities and involvement from choral groups, foreign language clubs, and to lacrosse. Each student is able to find a group, or several groups, and make friendships that are everlasting. It is true about what they say about our school, we are one "Royal Family".

    • Penn-Delco School District, PA
    • 9-12
    • 172

    Alum: Sun Valley High School is a great school and I'm glad I spent my high school career there. That being said, SV is also what you make of it. I know a lot of kids who skated by and did the bare minimum. They tend to be the ones complaining about how they hated SV. If you get involved, keep on top of your studies, take AP classes, and use all the resources SV has to offer, Sun Valley is a great high school! I'm proud to have graduated SV with a 4.4 GPA and I was accepted to all the colleges I applied to. GO VANGUARDS!

    Parent: This school doesn't have the greatest reputation, but I feel it is all in what the kids and families are putting into it. I graduated from this school many years ago and had no problems. My kids are in honors classes and have a good circle of friends so not having any problems. The stories I hear about the 'bad kids' are ones that have little parent involvement in their schooling.

    Senior: It's very fun. S.T.E.M has a lot of new classes that they isn't have bakc when I was a freshman . The classes I enjoy the most are sound production, film production, band, and music. Most of the teachers are nice and they are good people to go to if I have questions about college or life after high school. S.T.E.M is not like your average high school and they are preparing us for the real world.

    Senior: Although many people may say or think Chester High School is a bad school, it really is not. Chester High School is a school full of students with the will and potential to be something in life. Teachers travel from different areas of the state to come a guide the students here with the opportunity to further their education. Also, the teachers here are extremely encouraging and worth the listen!!! Guidance counselors are always there to guide you in the right direction and the principal is always putting forth the necessary effort to construct and conduct a school in desperate need of leadership assistance. Lastly, the schools activities are astounding. With reading teams and sports that are built to not only entertain you, but to show you how things are truly done in that particular field. So when you hear this school is bad think about it and actually come visit sometime, you'll see why anyone would be excited to be enrolled at Chester High School. Thank You
