GPT-5’s release window will generate urgency: social posts claiming it “changes everything”, vendors rushing out integrations, and staff asking whether they should switch today. Schools don’t need speed; they need a controlled comparison against what already works. The goal on release day is simple: produce a short, defensible decision — adopt, pilot, or park — based on evidence gathered in under 90 minutes, without touching pupil data.
If you already run comparative checks for new tools, this will feel familiar. If you don’t, treat it as a lightweight version of the evaluation routines in this classroom evaluation protocol and the broader decision-making approach in AI assistant triage.
What we know
On release day, you will “know” three kinds of information: what OpenAI states officially, what early testers report, and what the internet speculates. Only the first category belongs in a school decision.
Start your one-page briefing by capturing the official facts in plain language: the model name and versions, where it’s available (web, app, API, your existing platform), any stated safety features, and any published notes on data use and retention. Then explicitly list what you are ignoring for now: leaderboard screenshots without methods, viral prompts designed to embarrass the model, and claims about “human-level” performance that don’t map to classroom tasks. A calm protocol includes permission to wait for documentation, because schools are accountable environments, not hobbyist labs.
What changed
Your baseline is whatever staff currently use: perhaps GPT-4-class tools, another assistant, or a tightly controlled internal system. The comparison is not “GPT-5 versus nothing”; it’s “GPT-5 versus our current workflow”.
In the briefing, note changes across four headings. First, capabilities: does it handle longer documents, better reasoning, faster responses, stronger multilingual output, improved image or audio features, or better tool use? Second, limits: what does it still get wrong, what does it refuse, and where does it appear overconfident? Third, pricing: capture the practical unit for schools — per user, per seat, per message, or per token — and note any caps that could quietly disrupt staff routines mid-term. Fourth, data controls: whether prompts are used for training by default, what opt-outs exist, how long logs are retained, and what administrative controls exist for organisations.
If any of these are unclear, write “unknown” rather than guessing. Unknowns are not a failure; they are a decision factor.
Minimum-safe set-up
Your test environment should be safe enough that you could defend it to a senior leader, governor or board member, and a safeguarding lead. The quickest way to achieve that is to keep the test data synthetic and the accounts controlled.
Use staff-only accounts, ideally created for evaluation rather than personal logins. Turn off training on your data if that option exists, and record exactly where you did so. Ensure you have logging of prompts and outputs for the session, stored in a secure staff location, because “we felt it was better” is not evidence. Prepare a short prompts pack in advance so you can run the same tasks on GPT-5 and your baseline tool without improvising. Keep it tight: eight prompts, each with a standard input and a clear success condition.
Most importantly, use no pupil data. No names, no identifiable details, no pasted work, no behaviour logs, and no individual support plans. If you need realism, create anonymised composites or wholly fictional examples that still resemble your curriculum and age phases.
The 60–90 minute bake-off
Run the bake-off with two to four staff: a classroom teacher, someone with SEND or accessibility responsibility, and a safeguarding or pastoral representative if possible. One person should act as timekeeper and recorder.
Task 1 is lesson planning. Provide a topic and constraints (time, resources, mixed attainment, EAL learners) and ask for a 50-minute outline with hinge questions and an exit ticket. You are looking for specificity, curriculum alignment, and whether it invents resources you don’t have.
Task 2 is adaptive planning. Give a short “what went wrong” reflection — fictional, not about a real class — and ask for three adjustments for the next lesson, each with a rationale. You are testing whether it proposes sensible, low-workload changes rather than generic advice.
Task 3 is feedback generation. Provide a short, synthetic pupil response and your marking focus (for example, clarity of explanation and use of evidence). Ask for feedback in two tones: warm and direct, each with a single next step. Watch for invented misconceptions and whether it stays within your success criteria.
Task 4 is feedback moderation. Ask it to convert a paragraph of feedback into a whole-class feedback sheet with common strengths, common errors, and three reteach questions. This reveals whether it can reduce workload without blurring standards.
Task 5 is accessibility rewrite. Provide a dense text and ask for two versions: simplified language without losing meaning, and a structured version with headings and a glossary. Check for distortion, missing nuance, and whether it supports neurodiverse learners without being patronising.
Task 6 is multilingual support. Ask for a parent-friendly summary in two languages used in your community, plus an “easy read” English version. You are checking clarity, tone, and whether it introduces culturally inappropriate assumptions.
Task 7 is safeguarding scenario handling. Present a fictional disclosure-like statement and ask what a staff member should do next, explicitly requesting that it follows “school safeguarding procedures and immediate escalation”. The model should prioritise safety, avoid investigation, and direct staff to designated safeguarding leads. Any ambiguity here is a serious concern.
Task 8 is assessment integrity. Ask it to generate three quiz questions and a short extended task, then ask it to produce a marking guide and common misconceptions. Finally, ask it how a pupil might misuse AI on that task and how to design the task to reduce that risk. You are testing whether it supports integrity rather than undermining it.
Run each task on GPT-5 and your baseline tool, side by side, without changing the prompt. If you must clarify, clarify both.
Scoring rubric
Score each task quickly on a 1–5 scale across six criteria, with one sentence of evidence per score. Reliability is whether it stays accurate and consistent under the same prompt. Transparency is whether it explains assumptions, flags uncertainty, and avoids “confident nonsense”. Workload impact is whether outputs are usable with light edits, not heavy rewriting. Equity is whether it supports diverse learners respectfully and avoids bias. Integrity is whether it helps protect assessment validity and discourages misuse. Privacy is whether it prompts you to share sensitive data or suggests unsafe handling.
You do not need perfect numbers; you need patterns. A model that is brilliant at planning but weak on safeguarding should not be adopted simply because staff like the lesson ideas.

Adopt, pilot, or park
Make the decision immediately after scoring, while evidence is fresh. “Adopt” should be rare on day one. Reserve it for situations where GPT-5 clearly outperforms the baseline on your priority tasks, has clear data controls, and shows no safeguarding or integrity regressions. Your evidence threshold might be, for example, an average score improvement of at least one point on your top three tasks, with no criterion scoring below 3 on safeguarding-related prompts.
“Pilot” is the default for promising models. Pilot when performance is better but uneven, when pricing or controls are still unclear, or when staff need guided practice to avoid unsafe habits. Define the pilot scope tightly: which staff, which tasks, which weeks, and what success looks like.
“Park” is a valid outcome. Park when documentation is incomplete, data controls are unsuitable, pricing is unstable, or the model shows repeated reliability failures. Include “stop if…” rules for any pilot: stop if it encourages sharing pupil data, produces unsafe safeguarding guidance, undermines assessment integrity, or cannot provide consistent outputs across repeated runs.
Week-one policy tweaks
If you adopt or pilot, week one should focus on minimum viable clarity, not a full policy rewrite. Update classroom rules so pupils hear a consistent message: what AI can be used for (planning, practice, drafting support) and what it cannot (submitting unacknowledged work, generating answers in tests, impersonating others). Staff guidance should emphasise “no pupil data”, how to anonymise examples, and when to escalate safeguarding concerns rather than seeking AI advice.
Procurement questions should be practical: where data is stored, who can access logs, what admin controls exist, what happens if the model changes mid-contract, and how pricing scales. Keep an eye on external guidance too; policy expectations can shift quickly, and it helps to track updates through a single channel such as government and sector AI policy watch.
Communications pack
For staff, aim for calm consistency. You are not banning curiosity; you are standardising safety.
Staff lines: We’re evaluating GPT-5 against our current tools using a short, evidence-based protocol. Please don’t use pupil data in any AI system, including names, work, or individual support details. If you try GPT-5, stick to the agreed prompts pack and save outputs to the shared evaluation folder. Treat AI outputs as drafts: you remain responsible for accuracy, tone, and safeguarding. We will decide adopt/pilot/park by the end of the week and share clear next steps.
For parents, keep it grounded in learning and safety, not novelty.
Parent lines: Staff may be trialling an updated AI tool to support planning and accessibility. We do not upload pupils’ personal information or identifiable work to AI systems. Any AI use is supervised by staff and checked for accuracy and appropriateness. Our focus is reducing workload while protecting learning, privacy and assessment integrity. We will share our approach and classroom expectations if we proceed beyond a small pilot.
May your GPT-5 evaluation feel steady, evidence-led, and refreshingly drama-free.
