Major technology companies are rolling out AI chatbots and automated tutors in K–12 classrooms and district pilots, scaling tools that promise personalized help but draw warnings about erosion of instruction and assessment integrity. Education leaders and ed‑tech researchers report growing supplier activity and fast adoption by some districts. Higher-education institutions that prepare teachers, certify ed-tech research, or host teacher-training programs should monitor these deployments closely: teacher-preparation curricula and campus licensing/partnership policies will need updates to address classroom use, evaluation metrics and data-privacy safeguards.
