Tower Hill School

• Private School
• Wilmington, DE
• PK, K-12
• 32

Parent: Overall a more challenging school academically then the other private day schools in Delaware. Students are competitive but kind. Atmosphere is fair with a strong emphasis on students taking full responsibility for their academics, sports and creative endeavors. My son was at another private school in the area for K-8 and moved to THS in 9th grade. He has to work harder academically but he couldn't be happier. College prep starts in 8th and 9th grade. There are many clubs and opportunities for students to lead or try new things. Faculty is top notch. Most of my sons teachers have taught at the college level and some have PhD's. Great facilities for sports, drama and the sciences too.

• PK, K-12

Parent: I feel so fortunate that my children were able to attend WFS. It has been a transformative experience. Yes, the education was exceptional, but the community is amazing. The staff connects with the students, offers them opportunities, and encourages them to become their best selves! Especially in these times, I think it's so important to have an education grounded in values and I can't think of any better philosophy than one of "that of God in everyone."

The Tatnall School

• Private School
• Wilmington, DE
• PK, K-12
• 58

Junior: Tatnall has helped shape who I am as a person. The motto is "Omnia en Caritate," meaning "All things in love," and I can say without hesitation that this is true. Before I came to Tatnall, I attended a different private-day school in Delaware, but I can assure you, Tatnall is different. Here, I work with instead of against my teachers. All the teachers know me personally as a student, my strengths and weaknesses, and how I learn best in the classroom. The teachers are truly the reason I came to Tatnall and it would honestly not be such an amazing school without them.

Ursuline Academy

• Private School
• Wilmington, DE
• PK, K-12
• 84

Niche User: Ursuline Academy is an amazing school. I truly believe that an all-girls education is worth the tuition of UA. The academics are well balanced and prepare you for college life. The counselors at UA always make sure you are where you need to be and that you have the materials you need to be successful. The teachers are alright. Once in a while you may get a teacher who isn't the greatest, but overall the teachers are amazing and by the time you graduate they become like friends. The sisterhood at UA is the greatest thing about the school. You really feel like all the girls here are your sisters. There is some diversity at the school, but I feel like there should be more.

Padua Academy

• Private School
• Wilmington, DE
• 9-12
• 167

Parent: Padua Academy has done an outstanding job of transforming girls into confident, faith based young women, who are well prepared for the rigors of college life. From day one as a Freshman, Padua starts the college process in their students by instilling the three S's, which are, Scholarship, Sisterhood and Service. The girls are both guided and challenged throughout their 4 years; academically and through the actions of their faith by the initiation of community service, and various service projects that extend beyond the boarders of the United States. Padua Academy also provides international student studies, which allows for a multicultural and global diversity of learning both in and out of the classroom. Although Padua Academy is a little bit of a financial sacrifice from a parent prospective. The end result you will see in your dauther, is priceless!

Works Here: Saint Thomas More Academy offers a great college preparatory curriculum.

There are so many opportunities for students to engage in leadership roles, extra-curricular clubs/activities and athletics.

Red Lion Christian Academy

• Private School
• Bear, DE
• PK, K-12
• 15

Alum: I had an amazing time at Red Lion Christian Academy. Not only was I able to be involved with multiple sports teams year round, but I also took part in the incredible school musical, choir, arts department, and student government. I was class president for 3 years and the student body my senior year. I was very close with the students, parents, and faculty. I tried to do every extra curricular activity offered, and they were abundant! No matter what you are interested in here, teachers care about you and your needs and want to help you in any way possible. They go above and beyond to create real and lasting relationships that are still strong even after graduation. Every school has ways to improve, RLCA included, but they are doing a great job keeping up with the times and making sure they are Christ, student, and family based.

Wilmington Christian School

• Private School
• Hockessin, DE
• PK, K-12
• 61

Alum: While I was at WCS I learned the joy in helping others. I saw how I could serve others and bless them. There were struggles that I could help with, the problem though was the fact that no one wanted to point out these struggles. Everyone knew they were there, or at least those who invested any time into school. Problems like peer pressure and indifference among everyone that caused so much unnecessary anxiety. For example, this is a Christian school where Christians go to learn a Christian perspective on subjects and the world and yet some people felt they shouldn't need to hear about Christ. WCS was a great school and it has some teachers who truly put so much care into their work. Every school has issues and WCS isn't an exception, but there's no doubt they invest in influencing in the future of their students.

Delmarva Christian High School

Alum: A Christ-centred school that lives up to its mission to "prepare students spiritually, academically, and physically, to know and do God's Will in their lives'". I attended DCHS all four years and graduated Salutatorian out of a class of 42, but don't let the small class size discourage you—this school has intimate lessons built for students who want to learn! And believe me, the school lives up to its academic profile by thoroughly preparing teens for college.

Niche User: This school is unique because it is a small school that strives for excellence while maintaining a family atmosphere. Some of my favorite events to attend are the sports games, the Christmas program that the kids put on every year and the family events like Grandparents Day. The administration and staff are great people to work with and I immediately felt comfortable putting my children in their care. I plan on keeping both my children there until they graduate.
