This study explores opportunities to learn within and across student teaching placements.The authors analyze the degree to which placement experiences present equitable opportunities for PSTs to build a specialized knowledge base. The authors found that all participants repeatedly praised student teaching for nurturing emerging professional identities and conferring new self-confidence. Specifically, the authors address three core strands of opportunity reportedly experienced by participants. These include opportunities to learn about curriculum and content; opportunities to see and participate in, but usually not plan for, “what’s possible”; and opportunities to struggle with and for youth.
