RECIPROCAL MUSEUMS (ASTC and ACM)
What is COSI’s reciprocal admission policy?
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.
View Reciprocal Policy
Are there any restrictions to the ASTC Travel Passport Program?
To receive Travel Passport Program benefits, you must live more than 90-miles away from the center/museum you wish to visit. The admission staff has the right to request proof of residence to apply the benefits. 90-miles is measured "as the crow flies", not by driving distance.
Additionally, Science Centers/Museums located within 90 -miles of each other are excluded from the Travel Passport Program unless exclusion is lifted by a mutual agreement. 90-miles is measured "as the crow flies" rather than by driving distance.
*This 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.
View Reciprocal Policy
Is my COSI membership valid at other museums?
Please note the following exclusions to the ASTC Travel Passport Program:*
Participating science centers and museums located within a 90-mile radius of COSI are excluded from the program. COSI Members visiting the Boonshoft Museum of Discovery (Dayton, Ohio), the Works (Newark, Ohio), and the SPI-Spot (Mt. Vernon, Ohio), will receive 50% off general admission due to separate reciprocal agreements.
COSI Members are ineligible for Passport Program benefits at science centers and museums within a 90-mile radius of their primary residence. 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 participating science center/museum you plan to visit, not driving distance.
