"Calli war nach dem ersten Tag schon begeistert und wurde mit offenen Armen empfangen. Er ging immer voller Freude in die Schule und schloss sehr gut in der 6. Klasse ab. Seine kleine Schwester Tilli ist nun in der 3. Klasse, spricht sehr gut Englisch (mit einem süssen amerikanischen Akzent, den sie wohl von ihrem Lehrer abgeguckt hat) und liebt Französisch! Beide Kinder waren und sind hier sehr gut behütet. Calli kommt, obwohl er schon in der 8. Klasse ist, immer gerne zu Besuch!"

Dory Czech, Mutter

"Very warm and professional welcome from the very first day across the entire SIS team. Great learning environment with plenty of opportunities for the kids to explore and develop. Our son loves going to SIS every single day and we do not want to miss the excitement anymore."

M. and S. Leitner, parents

"We have been extremely happy with the school and the education our children have received. The school is well run and the education structured and delivered in a caring, intelligent way. Our children, though different, both really enjoy school and are happy. The day structure has allowed us both to work while ensuring our children were well supported in their learning in both languages in a holistic environment."

"Uns ist das beste passiert, was Eltern passieren kann: Unsere Kinder sind gerne zur Schule gegangen! Der Grund ist sehr klar. Wir hatten jederzeit engagierte Lehrerinnen und Lehrer, die sich mit viel Herzblut für die Kinder eingesetzt haben. Das (Lern-) Umfeld stimmt."

Volker Probst, Vater

"What we love about our teachers is that they captivate children’s passion and curiosity. They are very child-centric, and proactively keep the parents in the loop as needed. As a working mom, I feel I am a full partner in our children’s learning and I extremely appreciate the time staff take to keep us in the loop of what is going, way before we ask for it. "

Idil Wittmann-Abubakar, mother

"We appreciate that our son loves to go to school, he learns and grows in a very caring and inclusive environment. As parents, it is important for us to have open discussions with the teachers about the progress of our son and this is exactly what we get. We also love to read the weekly summary of the teachers about everything the kids did and learnt!"

Tünde Lukacs, father

"The teachers are extremely attentive and caring to the children to help them navigate through the new environment and experiences. They learn through play and songs which makes school so much more fun for the kids. Our son has benefited from this and has developed tremendously socially and in learning in the first 1.5 years at the school. We are so happy that we have also registered our little daughter to join the school next year."
