Inclusion is too often discussed in terms of what happens when pupils struggle. The intervention, the adaptation, the pastoral response, the support plan. These things matter, but they are not the whole story. In a previous Schools Week article, I argued that key stage 3 had become “the wasted years” for too many pupils. The responses since then have confirmed something I suspected. The problem is not just about curriculum design. It is about what we believe pupils deserve. At key stage 3, the deeper question is this: what are pupils being included in? Are they being included in rich knowledge? In demanding texts? In the language of the subjects? Or are some pupils being included in a thinner version of the curriculum because we have decided, often with the best of intentions, that this is what they can manage? This matters because key stage 3 is a particularly precious phase. Years 7, 8 and 9 are not a bridge between primary school and GCSE, a holding bay or a rehearsal for examination courses. They are the years when pupils should encounter secondary education in its fullest sense. For many pupils, especially those without extensive vocabulary, background knowledge or the wider conversations beyond school that help to make sense of new ideas, key stage 3 may be the most important opportunity they have to build those foundations. That is why the curriculum offer at this stage needs to be generous. But generous does not mean overloaded. It means taking care over what is selected, how it is sequenced and how pupils are supported to enter into it. The danger is that, in our desire to be kind, we sometimes lower the pitch. We simplify too quickly. We replace the original source with the worksheet and reduce the complexity of the idea before pupils have had the chance to grapple with it. What access really means We assume that access means making things easier, when sometimes access means making the route into difficulty more carefully designed. Low pitch is not kindness. It can quietly close doors. This matters especially for pupils with SEND and those with lower prior attainment. They do not need a diluted curriculum. They need one which is ambitious enough to be worth their time and carefully enough taught for them to succeed within it. Consider a year 7 pupil with dyslexia encountering a demanding historical source. The question is not whether to remove the source. It is how to scaffold the encounter: pre-teaching vocabulary, reading aloud, breaking analysis into stages. Scaffolding keeps the destination intact. It says that this material is worth your attention. Dilution changes the destination. It says, often implicitly, “this is probably not for you”. Pupils notice this. They notice when the work they are given is thin. And, over time, they can internalise the message that serious knowledge belongs elsewhere, to other pupils, in other groups, in other classrooms. An ambitious key stage 3 resists this. It asks how all pupils can be brought into the disciplinary heart of the subject. In history, it might mean moving beyond simplified timelines into evidence, causation and genuine historical thinking. In English, it might mean reading whole, demanding texts rather than extracts stripped of their depth. This is not about making key stage 3 grand or abstract. It is about being precise about its purpose. A strong key stage 3 curriculum builds knowledge over time, pays attention to vocabulary, and returns to important concepts because understanding deepens through revisiting. It uses assessment to find out what pupils have understood, not simply what they have completed. Time to think It creates classrooms where pupils are expected to think hard, but where the culture is safe enough for them to do so, where demanding work is normal, mistakes are useful and pupils are given time to think. If we are serious about inclusion, we need to ask searching questions. Who gets the richest curriculum? Who reads the most demanding texts? Who is invited into complex ideas? And who is quietly given less? These questions are not about blame. Schools are working under enormous pressure. Staffing, accountability, behaviour, workload and funding all shape what is possible. But precisely because time and energy are limited, we need to be clear about what matters most. And what matters is that pupils are not just present in school. They are present in the curriculum. That is why key stage 3 deserves serious attention. It is where entitlement either expands or narrows, where pupils begin to see what secondary education is really offering them and where they build the knowledge and habits that shape later success. Inclusion without ambition is not enough. Belonging matters deeply, but pupils need to belong to something intellectually worthwhile. That is not a luxury for some children. It is an entitlement for all.
