The Children's Museum of Indianapolis, founded in 1925, is one of few children's museums with a substantial collection. The changing needs of family audiences, and the museum's shift in direction toward a family learning mission, began to raise several questions for the collections and curatorial staff regarding the selection of objects that would hold the greatest potential for use with family audiences. The questions led to the development of the Family Learning Object Rating and Evaluation System (FLORES). This case study describes the development of the rating instrument and strategies the team took to fine-tune its use through input from curators and museum visitor preferences. By drawing on inherent object qualities as well as visitor preferences, museums can find ways to better understand the visitor-object relationship and in turn move toward more intentional selection and inclusion of objects in exhibition planning
