We are an accredited member of the Educational Collaborative of International Schools (https://www.ecis.org). This organization helps member schools in the following five key aspects:
- attracting, promoting and maintaining talented teachers
- using fixed assets and perishable assets
- information management
- protection of integrity and standards
- facilitating the transformation of educational ecosystems
We are registered in the register of non-public schools maintained by the Education Office of the Capital City of Warsaw. The accreditation and duties of a private school oblige us to follow good teaching practices and standards, as well as to ensure compliance of health and safety procedures with Polish regulations.
