The piece provides an introduction to City-As-School and briefly describes how faculty members have used Descriptive Inquiry to foster whole school professional learning and growth. The piece then details how the faculty used Descriptive Inquiry to surface and concretize shared educational principles during the 2020-21 school year, a poignant example of Patricia Carini's notion of "making and doing philosophy in a school."
