ISS Schools & SISU Schools®
In addition to working with more than 1200 international schools around the world each year, ISS directly owns, operates, or manages more than 20 distinguished international schools every year. Our newer SISU schools, based on the best of Finnish and American educational principles and practices, are rapidly growing as well, with more than 10 schools licensed in the first two years of the SISU Schools launch.
