School libraries play a powerful role in enabling, informing, and sustaining student agency, and nothing engages and motivates students more deeply than enabling them to become the active agents in the process of learning. Students with agency are powerful learners who are prepared to engage with the world with sustained, courageous curiosity. Both integrity and efficacy come together to build a sense of agency in which students own a strong perception that they are the key agents of their learning. This mode of learning shifts the locus of power from the teacher to the student, thus setting up students as the experts in their own learning. The traditional hierarchies of power in the classroom and school library are dismantled, and student agency can grow in an atmosphere of personal ownership and self-determination
