ISS OPtimize International School Services

SISU Schools®

SISU Schools® are a revolutionary K-12 program that uniquely blends the best educational practices from two of the world’s most acknowledged and recognized educational systems: Finnish and American. The SISU program covers the entire K-12 educational continuum and can be used in any country and in any language. The SISU Schools® Model gives you the option to open an international school on a shorter timeline, with an array of standardized plans and policies.

The SISU School® K-12 franchise model is rapidly growing across the international school landscape, with sites planned on at least four continents. The concept and franchises are made possible through the collaboration of two educational leaders: International Schools Services (ISS) and Lumo Education Ltd. In less than a year, the ISS-Lumo team has signed 10 SISU Schools contracts, and has more in progress.

The SISU Franchise Model

Creating affordable, quality education can be challenging for investors and educational entrepreneurs, but the SISU franchise model is highly structured and standardized, while still retaining a degree of flexibility.

The SISU approach allows owners to move from concept to opening to impact in a relatively short period of time, due to a robust set of deliverables that accompany the school license under the SISU brand. Along with the SISU process, these deliverables ⁠— such as guidebooks, policies, marketing, architecture, school supply, curriculum, teacher training, recruitment, quality assurance, and practically any other elements that the school needs ⁠ ⁠— are honed to save prospective owners the considerable cost and time typically consumed by activities associated with starting and operating a school.

The school concept, content, and support are all included in SISU Schools franchise model. The school owner secures the premises, school license, and funds to cover the operational expenses, which typically require some investment in the first one to three years of operations. After that, most schools are expected to be at a break-even point given adequate enrollments and other factors, which is relatively swift in the school sector.
