SIS Swiss International School has become a strong brand that stands on its own. Referencing it to its parent companies in a prominent way is not necessary. In the rare event that the logos still need to be used, the following rules apply:

Always position the logos in a less prominent position than the SIS logo  (i.e. never above the SIS logo).

Print the logos smaller than the SIS logo on all SIS print products and MS Office documents (reference point: 75 %).

Never use either of the two logos alone. If you use them, always use them together.
