Open days

Visit us at one of our open mornings from 9-11am

*** We currently have postponed all open mornings for 2020, to make sure we keep everybody safe. Hopefully we are able to welcome you in our school again soon. For now, watch the introduction video below and we are happy to set up a skype call as well. Just register your interest through our admissions page, and we will do the rest!***

At Optimist International School we understand how important it is to choose the right international school for your child. We therefore like to invite you and your child to come to one of our open mornings. A great way to get a feel of our school and find out whether you think your child will be happy at OIS.

During the open mornings you will get a tour of school. Stichting Kinderopvang Haarlemmermeer (SKH) will also be present to give you a tour of the BSO facilities next door, as well as Koops Expat Services who will be able to answer any questions about rental properties in and around Hoofddorp.
