In recent years, there has been growing attention towards collaborative efforts between museums and schools to advance education for children, known as museum-school partnerships. These partnerships enhance educational activities, as reflected in museum laws and educational guidelines, which encourage cooperation between museums and schools. Zoos and aquariums, as a type of museum, offer programs tailored for schools, including both on-site visits and off-site programs conducted within schools. In this study, as part of the museum-school partnership initiatives conducted at zoos, we conducted a web survey to assess the availability of information on off-site programs, including outreach sessions, loaned educational materials, and other activities. The results revealed that out of 137 surveyed institutions, 62 offered off-site programs, comprising 25 institutions offering loaned educational materials, 28 providing outreach sessions, and 53 offering other forms of engagement.
