COSI Reciprocal Policies

Participating members of the Association of Children’s Museums (ACM) Reciprocal Network receive 50% off general admission for up to six people. ACM members must present their participating museum’s membership card and photo ID with their advanced COSI reservations at the Box Office.

The ASTC Travel Passport Program entitles members of participating museums free or discounted admission at 360+ ASTC (Association of Science-Technology Centers) museums. COSI will admit a maximum of two adults and four youth (age 18 and under) that are on a reciprocal membership. ASTC members must present their participating museum’s membership card and photo ID with their advanced COSI reservations at the Admission Desk.
Note: ASTC reciprocal admission benefits do not apply to members whose place of residence is less than 90 miles from COSI. Per ASTC policy, this distance is measured “as the crow flies”, meaning that it is based on a straight line between your residence and COSI, not driving distance.

*ASTC & ACM reciprocal admission cannot be used together or combined with any other special offers, promotions or discounts.
