Alum: I transferred to Riverstone in my junior year and the community welcomed me right in. Even before I entered the school year, I was connected with a "buddy" and I started to exchange emails with her to chat about classes and etc., which became a great way for me to learn about Riverstone. I was one of the very first residents at the dorm, which is a beautifully renovated complex on the River Street. Our dorm parents of the time, Margaret and Mary, were extremely caring. I really enjoyed the experience of living with kids from all over the world and learning about their cultures and experiences. The academics at Riverstone was definitely challenging and the faculty there were top-notched. The IB program was the hardest thing that I have ever done and it truly prepared me for college. When I started my freshman year at BU, classes felt relevantly easy, or that I would have the tools and capabilities to learn. Overall, I really couldn't thank Riverstone enough for everything!...

Sophomore: All of my teachers are absolutely incredible. I look forward to learning in every class daily. We spend time outside and the school outdoor program trips really tie everything together. As a student that is new to town, this school has welcomed me with open arms. I love it there and have absolutely nothing negative to say about it.... Read 37 reviews

Parent: A true education partnership with students and families! Our oldest child spent 7 wonderful years at this school (6th-12th), and our youngest is currently a student here. The students are able to dive deeply into real world problems and engage in field studies that allow them to have real connections with what they are learning. I love this! They take part in community service each week and interact with many local organizations. They are given the space and opportunity to find their voice, and use it, and learn to collaborate with other students, teachers and community members. The school cares deeply about the students and works to provide the space for individual learning opportunities too. This is a rigorous education and prepares the students for college and life beyond. I can say this because our oldest child is now in college and thriving, academically and socially....

Senior: I moved to Bishop Kelly High School in the middle of junior year. It was quite a drastic change in my environment, because my previous high school was a small charter school with an IB curriculum, while Bishop Kelly High School is a Catholic high school and is bigger. The best parts of my experience was definitely the prevalence of faith in the school and how it helps connect others, such as the retreats that are offered and the daily prayer, and monthly masses. However, the worst part was most definitely the huge mental challenge of me switching schools. I had to endure making new friends in an unfamiliar environment whilst maintaining grades in a new curriculum. But, I feel that it was the right decision to move to Bishop Kelly High School, because it ultimately helped me grow as a person, with the bustling and connected community, and the success-oriented environment, and the adamant faith life....

Alum: It is an amazing school that puts a great focus into a humanities based education. Due to the small class sizes, one on one help is much easier to obtain. The atmosphere is great for all ages, Pre-K -12. The extracurricular activities programs are constantly growing and improving which can help with various life skills and fun. Sports are always an option here. There are several events and fundraisers which are fun for the whole family. I would highly recommend that you look into enrolling your child here....

Senior: The best parts of Logos are the education you receive, and the people you meet on the way. This is a classical Christian school, which means we discuss real problems faced both in the past and in the present through a biblical lens. This of course could not be done without the teachers. The faculty are so encouraging and really engage their students in learning and leadership through Christ.... Read 27 reviews

Senior: Gem State Adventist Academy’s best quality is the friendly, welcoming environment that is created by both the students and the teachers there. Every single one of the staff members is professional and cares for the well being of their students. As a student who arrived later than most, everyone was incredibly kind and welcoming. The programs that Gem State Adventist Academy offers, not only provides fun and new opportunities, but allows for bonds and friendships to be built. Many of my fellow students attending believe the same way. Overall, Gem State Adventist Academy provides and experience unlike any other high school can, and gives beneficial opportunities for the students.... Read 18 reviews

Senior: Cole Valley has been an incredible experience for me. The teachers and staff genuinely care about me and provide so much support. I feel like I've had some great opportunities like the NASA engineering program. We were able to go to Houston and present our engineering projects, that was amazing. We've had so many opportunities to volunteer and give back to the community and it's all organized and encouraged by the school. My advisory leaders have had such a positive impact on who I am and where I am today. We have had several opportunities to go on retreats with other students and teachers. These retreats have been incredible and invaluable. I feel fortunate I was able to attend Cole Valley Christian.... Read 148 reviews

Senior: I came to Nampa Christian Schools in 7th grade and got involved in volleyball, which was new to me and met amazing friends that accepted me even when they didn't know who I was. I would recommend if you go there to get involved either with choir, sports, or theatre to get to know the people in your class and to get connected. It is hard to break into the groups that have been together for a long time, but if you jump in, they will warm up to you and you will find amazing friends, loving teachers, and exciting sporting events. I have enjoyed my time at Nampa Christian, but I think it has something to do with God's blessing, too. Seek Him at Nampa Christian, and I hope you are encouraged to find him in the smiles and friendly faces.... Read 51 reviews

Senior: Genesis Preparatory Academy was an amazing school to attend. Everything about the school from the atmosphere to the teachers to the curriculum was amazing and really tailored to my needs. I am a senior graduating this year and I will be attending the University of Idaho to eventually go onto medical school. I feel like Genesis Preparatory Academy has really helped me become the person that I want to be, and it helped me find out what type of person I am. I am grateful I found Genesis.... Read 9 reviews

Senior: I have been attending Christian Center School since the 2020-2021 school year. My experience there has been highly positive, and I am so glad I've had the opportunity to go there. CCS is unique from other schools in many different ways, but the most prominent one is the way the students love one another. Going to CCS has made me feel genuinely cared for, and I've met some of my dearest friends there. The environment is not only loving and positive, but it also helps students to grow in their Christian faith. All grades are required to take a Bible class, which is helps students gain knowledge behind their faith. Every other year, CCS juniors and seniors take a Spanish speaking trip to practice the Spanish that we've been learning. In May I was able to go to Costa Rica, which was an incredible experience. CCS offers some dual credit classes. I would like to see more offered. I would also like to see some of the strict policies be loosened, and perhaps hire some more qualified teachers....

Senior: I began attending GFA in the eighth grade after having been homeschooled my entire life. The small class sizes allowed me to easily become accustomed to such a different experience and promote a great class connection. The overall small school size makes communication with teachers, students, and administration a breeze. One of the things I appreciate is the fact that everyone, regardless of ability or athleticism, is given the chance to participate in sports. During my time here, I have grown as an individual from someone who was painfully shy, to a person ready to go out into the world. Greenleaf Friends Academy is a school that welcomes individuality and recognizes talents. If you are looking for a small school that focuses on community, service, character building, and excellence, I would definitely recommend looking into GFA!... Read 23 reviews

Senior: I definitely like the teachers there at House of the Lord Christian Academy. They have been very helpful with our studies and make sure that we are responsible for our grade. Everyone is very friendly and welcoming to new students and are easy to get along with. It's a enjoyable, safe environment that I would recommend to others. We have hot lunch once a week, so you'll have to bring your own food most of the time and we don't have any sports teams unless we get enough people to actually want to participate in that sport....

The teachers are so loving and deeply care not only for their students academic welfare, but more importantly their spiritual welfare. The Bible is infused throughout the school day, which makes me one happy parent to have my kids come home talking about Jesus!... Read 12 reviews

Parent: My son is on his 2nd and final year at NICS, he will graduate this year here. We have had such an amazing experience at NICS! From the staff to the students and our experiences with the sports programs we have nothing but great things to say. He came in struggling with his grades, he quit sports that he’s played most of his life and was in a bad place with all the negative experiences he had being at a local public high school. Because of the teachers working hard to help him get his grades up he is now thriving and will graduate on time with his class! He played sports both years, cheered from the stands for the girls and younger kids games and absolutely enjoyed all of it! He’s made some amazing friends and I know these kids will continue their friendships long after graduation. We have recommended another family here and they are having the same experiences! Highly recommend this school! Only regret is not finding this place sooner! Thanks NICS for the wonderful memories!... Read 28 reviews

Parent: Our children have been at Innovate Academy for the past two years, and we couldn't be happier! Our favorite part about Innovate Academy is how much our kids love learning. With a four day school schedule, we like that we have the freedom to spend family time with our kids. They don't seem to get burnt out, and they also learn the meaning of work-life balance. Academically, we have seen a ton of growth from both of our students year over year. We like that Innovate doesn't focus on memorization. The staff takes their time to make sure the students absorb a concept fully so that they retain it. They use project based learning to expand on subjects and ideas. We feel that our kids are learning how to learn, rather than learning how to memorize. We appreciate the school's unwavering traditional values, and we know that our kids are safe and loved. Thank you Innovate!... Read 5 reviews
