"One evening, a group of sixteen and seventeen year old students gave a party for us in a park outside Tel Aviv. There we sang and learned Israeli folk dances around a campfire." – Article from AISZ Yearbook 1964
John Mattern: First Headmaster of AISZ
"Early in the fall of my senior year, Dr Mattern suggested we have a school dance. We did and four of us were caught with some alcohol outside in the bushes during the dance... Dr. Mattern discussed our ‘punishment’ and that it needed to be an example to the rest of the students. He came up with the idea of a community service project and we do a fund raiser and contribute the proceeds to a needy cause which he helped us identify. Some months later, we organized and ran a fashion show which was a huge success and raised a very nice sum for our worthy cause. For the times, community service as punishment was unheard of and is an example of Dr. Mattern’s innovative ideas about education."

"My year 9 was a real stand out because we were in the temporary housing constructed on the fields during the renovation of the mansion. The temporary housing (lovingly known as the "Dorfs") was special in that all the school years were brought closer together. That year I became friends with students in years above and below me that I hadn't met before, and we all felt linked through a joint experience of being dripped on through the roof during heavy rain, freezing in winter, and overheating on hot days. It was brilliant."

The delight was the fact that teachers, administrators and parents all contributed, coming together in order to support a worthwhile cause (our children’s education). My mother was lucky enough to come over from England and attended one production and in the lead up to dinner, a silent auction and raffle took place. Mary Ann Canzanella kindly bought my mother raffle tickets, and this act of kindness is indicative of the care, thoughtfulness and spirit of what it means to be involved with ZIS (AISZ)."
– Steve Burnham

Valérie Horyna, Class of 2003

People have told me how much they value the special atmosphere that has existed at ZIS since the very beginning. For example, students and alumni talk about their incredible teachers who were mentors, coaches, and directors. They speak of the strength of these relationships and how faculty and staff go out of their way to meet their needs as students, and, most importantly, as people."
