From grading and college recommendations to extracurriculars and character development, K-12 schools are tasked with a near-impossible mission: to do it all, for everyone. At the same time, new technologies and education models offer opportunities to rethink and unbundle these roles—yet such transformation raises complex questions about trust, equity, and feasibility.
