What is COSI’s reciprocal admission policy?

COSI policy offers free admission for 2 adults and up to 4 children listed on a qualifying Association of Science-Technology Centers (ASTC) reciprocal membership. Participating members of the Association of Children’s Museums (ACM) Reciprocal Network receive 50% off exhibits admission for up to six people.

COSI checks IDs for reciprocal admission and strictly enforces the ASTC “90-Mile” reciprocal policy. ASTC reciprocal admission benefits do not apply to reciprocal 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 the linear radius between your place of residency and COSI, not driving distance.

COSI cannot verify memberships from reciprocal museums. Reciprocal visitors must present current membership cards and photo ID when checking in at COSI’s Box Office (General Admission line). Reciprocal admission includes all of COSI's classic exhibits and live shows. This does not include any upcharge traveling exhibitions. These and other additional experiences are available for purchase upon checking in.
