this is not meant as a negative about either school, btw, we are Americans and our kids all go to ISZL and love it. I don't have any experience with the schools other than ISZL and ZIS.
Smart kids don't need hand holding and go to regular kindergarten/school.
Based on other quotes this person is a bit dim themselves or only interested in demonstrating a total lack of respect for others opinions
During this time between them we have experienced grades 4-11 and have been impressed (especially with the middle and high school). The facilities and opportunities available to the kids are amazing.
I'm sure ZIS is also very good and your choice may come down to where you decide to live.
My youngest is in the Swiss school system, which is also very good, but she was young enough to start in the Kindergarten. I think starting in the Swiss system with no German at the grades that your kids are in would be very difficult.
I think you should take a decision mainly according to the following:
1) SBB travel plan and what is easiest for your children commuting.
2) Are your children gifted or talented or have special needs in a certain area, check with both schools and see what they offer for your childs` specific needs.
3) ZIS middle school is not a MYP school. If your a big fan of IB MYP and really believe in it then ZIS might not be the place for your child. I like IB MYP idea in general and I think it`s a brilliant philosophy. I also like ZIS middle school curriculum, very strong program that bridge between upper school and middle school nicely and neatly.
Good luck on your move"
Mine are at ZIS in the lower school. They are very happy and motivated to go to school every day.
ZIS is rather American I would agree but they also have a high proportion of Swiss students (according to admissions) and the really promote good are caring behaviour by the students.
Otherwise you need to find a private school eg. Kusnacht bilingual, Terra nova ( http://www.terra-nova.ch/ )
-More active parent network/more parent involvement at ZIS
-Stronger focus on technology at ZIS
-More diverse student population at ISZL
-ISZL seems to draw kids from wider geographic area than ZIS...this can be challenging as getting kids together after school requires more/longer driving
We live closer to Zurich so the proximity of the ZIS campuses were much more convenient for us. I believe there is a waiting list for many grades at ZIS...don't know about ISZL.
I'm sure you would be happy with either as both are good schools.
