Lighthouse AdvisorySLED AI Adoption Intelligence

K–12

Tonight's K-12 signal is that AI's value and its risks both depend on how districts run it, not just on access. A new English trial found a curriculum-aligned AI planning tool cut primary teachers' lesson preparation by about 49 minutes a week without lowering quality, but few teachers kept using it. A Washington survey links clear policy and useful training with teacher confidence. Meanwhile, Fairfax built its own browser extension because Google's admin console cannot switch off AI in search results. Orlando's board is asking whether Florida's opt-in and 30-day record rules are worth the cost and classroom strain.

Patterns across the evidence

Synthesis · Lighthouse Advisory interpretation

2 patterns, each supported by at least two sources
  1. AI built into vendor platforms is outrunning the controls districts need to enforce their rules

    Fairfax had to write its own Chrome extension because Google's admin console cannot switch off AI Overviews in search. In Orlando, the CIO said direct student use can include voice, image generation and embedded feedback, and the district is still asking vendors how to retain and return 30 days of student AI interactions. In both districts, policy depends on vendor features the districts do not control.

    Operating questionFor each AI feature our students can reach, which control enforces our policy, and which vendor feature are we relying on?

  2. Teacher AI value depends on fit and support, not access alone

    The English Aila trial found real time savings, yet use was low and fell over ten weeks, and gains concentrated among newer or less confident teachers. The Washington survey found that teachers with clear policies or useful training reported more confidence, and that attitudes split by subject. Neither source shows that simply providing AI tools changes practice.

    Operating questionWhich teachers and subjects are we targeting, and what policy and training will sustain use beyond the first weeks?

    EEF/NFER RCT: Oak National Academy's Aila cut primary teachers' lesson-preparation time by 24% without lower resource quality, but use was low and declining

    A randomised controlled trial in 108 English primary schools (464 teachers randomised; the project page reports data from 416) allocated Key Stage 2 teachers to use or avoid Aila, a free AI lesson-planning tool, for ten weeks in autumn 2025. Aila teachers spent about 2.5 hours a week on lesson and resource preparation versus 3 hours 19 minutes, 76% of the comparison time, saving about 49 minutes a week, and their resources were no worse in quality. The trial received a high security rating. Benefits were greater for newer or less confident teachers. Use was low: 81% tried it, it was used for about 7% of lessons in an average week, use declined, and fewer than one in five felt it meaningfully changed their planning or teaching.

    Why it matters, evidence and limitations
    Why it matters
    New, rigorous evidence on teacher-facing AI published today. It supports bounded time-saving claims for U.S. districts weighing teacher AI tools, while showing that free access alone did not sustain use. Transferability is limited: English curriculum, a purpose-built publicly funded tool, and a comparison group that could still use other AI.
    Evidence and measured results
    Independent RCT evaluated by NFER, with weekly teacher diaries, surveys and independent teacher assessments of resource quality; EEF high security rating. No pupil outcome measure; time is self-reported in diaries.
    Limitations and uncertainty
    England only; KS2 primary teachers; self-reported time; comparison group free to use other AI; low and declining use; developer is publicly funded and quoted in the release. Report PDF not opened; methods details from the linked project page.

    WTOP: Fairfax County Public Schools builds its own Chrome extension to hide Google AI Overviews because Google's admin controls cannot turn them off

    Fairfax County Public Schools, Virginia's largest district, says its filters already block student access to ChatGPT, Claude and Gemini, but Google's administrator controls give no way to disable AI Overviews in Google Search. Its IT department therefore built the FCPS Customizer, a Chrome extension that hides generative AI overviews, search summaries and image-search features on school-issued Chromebooks. It is rolling out at 11 elementary and middle schools first, with full elementary and middle school coverage expected by November. The district reports positive teacher feedback. The board banned generative AI for elementary students last summer, while teachers have a ChatGPT for Teachers pilot.

    Why it matters, evidence and limitations
    Why it matters
    Shows a concrete control gap: a district policy that bans student generative AI cannot be enforced through the vendor console when AI is built into search. A large district is filling the gap with in-house engineering, which most districts cannot do.
    Evidence and measured results
    Short news report based on a district statement; first reported by the Wall Street Journal. No usage data, effectiveness measures or teacher-feedback numbers are given.
    Limitations and uncertainty
    Based on a district statement; extension effectiveness, bypass rates and maintenance cost are not reported. Google's admin options may change. Single district.

    Central Florida Public Media: Orange County Public Schools maps Florida's AI rule and board members question opt-in workload, equity and 30-day record costs

    At an Oct. 6 work session, OCPS staff said existing policy already covers human review, approved tools, protected data, academic integrity and professional learning, but Florida's rule (18 requirements, effective July 1, 2027) adds parental opt-in, extra review of AI tools for pre-K through grade 5, record-keeping, reporting and vendor requirements. Families who do not opt in must get a comparable non-AI alternative. The CIO said direct use can include voice interactions, image generation and embedded AI feedback; district-reviewed generative tools include Adobe Firefly, Conmigo and Google Gemini Notebook. Board members raised teacher workload in split classrooms, unequal learning experiences, storage costs for 30 days of student AI interactions during budget cuts, and paying for unused tools.

    Why it matters, evidence and limitations
    Why it matters
    The archive holds Florida's rule and legal analysis; this is the first account of a large Florida district working through it in public, with concrete tool names, cost worries and equity objections from board members.
    Evidence and measured results
    Public-media reporting of a board work session with named officials' quotes. No cost figures; the CIO said costs depend on scope. Corroborated by WKMG News 6 coverage of the same session (not used as a separate source).
    Limitations and uncertainty
    News coverage of a work session, not a policy decision; costs not quantified; district awaits further state guidance (superintendent meeting the department this week).

    CWU College in the High School survey: 222 Washington math and English teachers split on AI, and clear policies and useful PD track with greater confidence

    In a May 2026 survey of 222 Washington high school math and English teachers, 57.0% of English teachers and 37.6% of math teachers said their attitude toward teaching had worsened since AI appeared; 83.7% of English and 54.9% of math teachers reported academic integrity concerns. English teachers were nonetheless more confident teaching responsible AI use (45.5% vs 24.4%) and more likely to require AI experimentation (34.1% vs 14.6%). Teachers with clear institutional AI policies, or useful AI professional development, reported more confidence using AI and teaching students to use it. About one-sixth of responses mentioned moving writing to in-class pen and paper, and some teachers had stopped assigning homework.
