AI in Education Digest — September 7, 2026

The first full week of September has produced a genuinely uncomfortable data point for anyone who assumed AI just helps students learn faster: a 30-month study of 27,000 students found that using generative AI on homework boosts scores in the moment but quietly erodes exam performance later. Meanwhile the policy response keeps hardening — New York City has finalised a ban on generative AI for its youngest students, and Florida is about to vote on rules covering everyone from pre-K to PhD. Here's what actually happened today.

New York City's Education Department has confirmed its revised AI policy: student-facing generative AI tools, including chatbots and AI tutors, are banned for the youngest 600,000-plus students in the nation's largest school system, from early childhood through middle school. Device screen time is capped at 30 minutes for grades 3–5 and 45 minutes for middle schoolers, and preschool-through-2nd-grade classrooms lose individual devices altogether, keeping only shared smart boards.

High schoolers get restricted access, with some use permitted for literacy and career-readiness programmes and in a handful of pilot schools. Teachers can still use approved AI for lesson planning, translation and drafting communications, but not for grading, behaviour monitoring or special education plans. The policy follows months of fierce parent backlash after an earlier, looser draft leaked in March.

2. Landmark 27,000-student study finds AI homework help cuts exam scores by 20%

Researchers tracked around 27,000 students aged 12–18 in China for 30 months, combining homework, monthly closed-book exam and high-stakes entrance-exam data across nine subjects. After students adopted generative AI, homework scores rose 18% and time spent per assignment fell roughly 30%, from 64 minutes to 45 minutes on average.

But when the same students sat monthly exams without AI, their scores fell 20% within six months, and performance on high-stakes entrance exams declined too, with the effect building over time. Researchers describe the pattern as "metacognitive laziness" — outsourcing the thinking, not just the typing, so nothing is left to recall under exam conditions.

3. Florida moves to regulate AI use from Pre-K through PhD

Florida's Board of Education votes September 16 on rules requiring every K-12 public and charter school, plus all 28 state colleges, to adopt AI policies. Schools would have to notify parents whenever a teacher approves an AI instructional tool, naming the platform and describing how students will interact with it, and provide a process for parents to opt out.

The draft explicitly bars AI from being used to meet a student's social or emotional needs, simulate friendship, or use "anthropomorphic design" to keep a student engaged. Separately, Florida's 12 state universities are moving to require every course syllabus to disclose faculty and permitted student use of AI.

4. University of Leicester becomes a UK-first with full Microsoft 365 Copilot rollout

The University of Leicester is giving all 21,000-plus students and 4,000 staff full Microsoft 365 Copilot access from this September, backed by mandatory digital-skills modules delivered through Blackboard before full access goes live. Leicester has been named one of Microsoft's first "Frontier" universities, embedding Copilot across teaching, research and professional services.

The move follows the University of Manchester's January 2026 announcement that it would roll Copilot out to all 65,000 of its students and staff, completed by summer 2026 — suggesting UK universities are now competing on institution-wide AI access as a selling point.

5. Maryland's AI Ready Schools Act deadline lands this fall

Governor Wes Moore's Artificial Intelligence Ready Schools Act gave every Maryland school district 120 days from state guidance to adopt a written AI policy before students returned this fall. The Maryland State Department of Education's framework sets out eight required elements, including data privacy, technology bias and keeping instruction "human-centered."

The law also pushes districts to address workforce-readiness skills for students alongside the guardrails, and requires teacher training as part of rollout.

Google is hosting a free, all-day virtual AI Educator Series event on Saturday, September 19 (9am–7pm ET), where teachers can work through training modules and earn digital AI-literacy badges at their own pace.

It's part of Google's broader push to get educators AI-ready at the start of the school year, alongside its wider AI Educator Series curriculum.
