    Riverstone International School Reviews

    We moved our daughter to Riverstone midway through her first grade year after having her in one of the more highly rated public elementary schools with excellent test scores. She is now in 3rd grade, and we have been highly impressed with the education she has received over the past 2+ years at Riverstone.
    At the public school, the larger class sizes and the big disparity in academic abilities prevented teachers from working with our daughter individually. Significant emphasis was put toward preparing the children to excel the standardized math and reading tests. This was the major deciding factor when making the switch to Riverstone.
    Riverstone is not teaching the kids to excel at testing. Rather, they are promoting creativity that has our daughter engaged and always excited to go to school every day! Riverstone's IB program is well-rounded and ties subject areas together for projects and field trips. They also have specialists teaching art, music, Spanish and Mandarin. Thank you!

    When our company relocated us last year, we researched all the possible education opportunities for our daughter. We visited public and private schools all across the Treasure Valley. We were almost ready to register her at one of the local parochial schools, until we gave her the opportunity to shadow. After her experience at both Ambrose and RIverstone International School, our daughter was confident RIverstone was the right choice. Even after our initial trip, when my husband later returned for a second look, the RIverstone campus was full of kids who were smiling and happy. We were so impressed with the obvious connections between students and teachers. Even the administration were clearly connected to the individual students.

    Our experience has not been without glitches here and there. However, the administration seems willing and able to listen and adapt as needed. Overall, our experience has been very good.
    We have enjoyed the small class sizes, engaging teachers, participating families, and encouragement for our children to grow and learn at their own pace. The outdoor experiences starting in Kindergarten are first-rate and provide an amazing opportunity to develop friendships, teamwork, and a love for the environment. It is a safe, loving, sometimes demanding, and always understanding space for kids bound for a successful future.
