Tuition & Affordability

Private education is an investment into your child’s future, which is why it takes time, research, and an understanding of what you want for them when choosing a school. 

Parents who enroll their children at ISM are looking to offer them a high-quality education that provides ongoing follow-up and support and individualized attention. They also want their children to have plenty of opportunities to explore their talent beyond academics and do so on an inspiring campus with plenty of room for them to learn and grow. 

To make this experience within reach for all interested families, at ISM, we offer generous Tuition Assistance for students in Kindergarten through Grade 12 for those who qualify. Eligible high school students are also encouraged to apply for a Taiylor R. Nunn STEM Scholarship.


We are committed to preparing our students for a successful future in college and beyond. With a 100% university acceptance rate and the ability for students to graduate with up to 18 Advanced Placement (AP) courses, most ISM students earn college credit and significant scholarships, which gives them a head start on their academic and career goals.

“One thing that makes ISM really stand apart is how they grow children to be leaders. As parents, children become the most important assets you have and K-12 education is probably the most important education that parents should be thinking about” - Arun B., ISM Parent


The value of an ISM education goes beyond just financial returns, offering students an enriching educational experience, a strong sense of community, and a lifelong love of learning that will have a lasting impact on their personal and professional lives.
