Tools now exist that can scan a piece of writing in seconds, flag features of a text against a framework, surface patterns across a whole cohort and give a teacher a useful summary that once took an evening of marking. Used well, these tools offer real value. They can reduce administrative load, speed up the mechanical parts of the process and give teachers a useful second pair of eyes. None of that is in dispute. What we must be clear about is the idea that any of this can replace human-led moderation. It cannot. Building an assessment approach that quietly assumes it might would be a serious mistake, both for the reliability of our judgements and for the professional development of the teachers making them. ## Writing assessment is a judgement, not a measurement The first reason is the nature of writing itself. Assessing a child’s writing is not like marking a maths paper. There is no answer key. A Teacher Assessment Framework describes a rounded profile of a writer. Reaching a judgement means weighing a body of evidence against that profile, holding the child’s writing in mind across time and contexts, and deciding whether it forms a secure and consistent picture. Two important parts of that judgement cannot be reliably established by analysing the finished text alone. The first is independence. A framework judgement rests on evidence that a child produced their writing independently. Independence is a fact about the conditions under which a piece was written, not simply a feature of the text on the page. A tool reading the finished writing does not know how much scaffolding, modelling or adult intervention shaped it. The second is authorial intent. Teachers consider whether a child made a deliberate, controlled choice or simply arrived at something by accident. The same comma, fronted adverbial or shift in tone might demonstrate a developing writer’s craft, or it might not. Telling the difference requires knowledge of the child, the wider body of writing and what they were trying to achieve. An AI tool can help identify what is in the text. It cannot reliably tell you how it got there or whether the child intended it. Those are precisely the questions on which a secure writing judgement can depend. ## Moderation develops teachers, not just decisions The second reason runs deeper, and it is the one most easily lost when efficiency becomes the main goal. The purpose of moderation has never been simply to arrive at the correct grade. Its wider value is that it develops teacher expertise. When teachers sit together over a body of writing, explain a judgement, hear a colleague identify something they missed and adjust their thinking, they are doing more than agreeing an outcome. They are calibrating their professional understanding. They leave a good moderation meeting as more confident assessors and, crucially, as better teachers of writing. The same expertise that helps a teacher judge a piece of writing accurately also helps them decide what and how to teach next. A judgement is a single decision about one child at one moment. Teacher expertise continues to develop and can improve the writing experience of every child that teacher goes on to teach. If the professional process is handed entirely to a tool, schools may gain a decision but lose an important opportunity for development. Saving time in the short term should not come at the cost of the shared professional knowledge that makes assessment work. ## The right relationship between the tool and the teacher None of this is an argument against AI. It is an argument about where it belongs. The most productive relationship is one in which the tool supports human judgement rather than substituting for it. Used appropriately, an AI assessment tool can help prepare the ground. It can gather and organise evidence, flag features for a teacher to examine, highlight inconsistencies worth exploring and reduce some of the administration that takes time away from genuine professional dialogue. That is a real benefit. It frees teachers to concentrate on the parts of assessment and moderation that require professional knowledge, including discussion, challenge, the weighing of evidence and the consideration of independence and intent. The principle is simple: AI can inform a judgement. It must not make the final decision. The moment a tool’s output is treated as a verdict rather than evidence for a teacher to examine, the safeguards that make writing judgements trustworthy begin to disappear. ## Using AI-generated feedback responsibly Schools also need to consider what happens after an AI tool has analysed a pupil’s writing. AI-generated feedback should not automatically be passed directly to a pupil. It must first be reviewed and, where necessary, adapted by the teacher. The teacher remains responsible for ensuring that the feedback is accurate, age-appropriate and appropriate for that particular pupil. Feedback should also reflect the wider teaching context. A tool may be able to identify a feature that is missing or inconsistent, but it does not necessarily know what has already been taught, what the pupil is ready to work on next or which feedback will be most helpful. Used carefully, AI can help teachers identify possible next steps. The professional decision about which feedback to give, how to explain it and how it fits into future teaching must remain with the teacher. ## What this means for school and trust policy A writing assessment policy that is fit for this moment should make these principles explicit rather than leaving them to chance. In practice, that means making several clear commitments. Human-led moderation remains the mechanism through which statutory and internal writing judgements are secured. AI tools are positioned as an aid to that process, supporting evidence-gathering and reducing workload, but never acting as the source of a final judgement. The two things an AI tool cannot reliably establish from a finished text alone, independence and authorial intent, should be recognised as the territory of informed professional judgement. Schools and trusts should also be clear about how AI-generated findings and feedback will be checked before they are used with pupils. Teachers need to understand the strengths and limitations of the tools being used, when to trust their signals and when their own judgement must lead. Finally, the developmental purpose of moderation should be protected as a deliberate investment in staff expertise, not treated as an administrative process to be automated away. ## How Pobble Moderation puts this into practice This is the principle on which [Pobble Moderation](https://www.pobble.com/moderation) is built. It is not a tool that hands teachers a verdict. It is an environment designed to make expert human-led moderation easier, more secure and more developmental, with much of the logistical burden removed so that professional dialogue can take centre stage. Pobble Moderation gives schools and multi-academy trusts a secure online space to run purposeful moderation meetings, share writing exemplars and moderate remotely or asynchronously across different sites. Removing the logistical burden is not about shortening the professional conversation. It is about protecting it, giving teachers the time and headspace for the calibration, challenge and shared judgement that help them become more confident assessors and more effective teachers of writing. That developmental purpose runs through everything we do. Alongside the platform, our training, external validation and expert-led moderation support are designed to grow teacher expertise, not simply deliver decisions. Independence and authorial intent stay exactly where they belong, with the professionals who know the children, understand the context and have read the wider body of writing. Pobble is also working alongside Air and Stylus to support schools and trusts exploring AI-supported writing assessment. The aim is to bring together the efficiency and insight AI tools can offer with the professional dialogue and shared understanding that secure writing assessment requires. ## Keeping professional judgement at the centre As AI assessment tools become more capable, it may be tempting to allow a plausible analysis or summary to stand in for a professional conversation, particularly when time is limited. We should be cautious about doing so, not because of nostalgia or suspicion of technology, but because we understand what moderation is for. Keep teachers at the heart of the process and let technology take care of the work that genuinely frees their time. Schools can then benefit from both: lighter administration and more confident, capable professionals. To help schools and trusts get this balance right, Pobble offers strategy calls, training, external validation and wider moderation support. Whether you are reviewing an assessment policy, deciding where AI tools fit or strengthening the way moderation develops your teachers, Laura Bailey, Pobble’s Head of Moderation and Assessment, can help you identify practical next steps.
