Discover key OFSTED deep dive questions to help teachers strengthen curriculum planning, improve subject delivery, and prepare confidently for inspections.
An inspection is an opportunity to clarify exactly what and how a school curriculum is delivered. It is as much for the school as it is for accountability measures (putting a positive spin on the experience!). There's a lot more to an inspection than a simple lesson observation and a chat with the curriculum leaders. An OFSTED inspector will expect to see how curriculum subjects are organised and delivered. The recent examination in school documents gave school leaders insight into what questions inspectors will ask and what type of knowledge they are looking for. In this article, we provide some extracts of what this looks like in practice. If nothing else, the questions can be used in staff meetings to help clarify how the curriculum is designed and delivered. The prompts below are an interesting reflection tool for discussions about effective learning and in this case, are solely focussed on an English subject examination.
Robinson and Wilson (2023) found the English curriculum helps learners become fluent. These practices support future achievement, argued Davis et al (2024). Skills like these benefit the learner, Smith (2022) noted.
How does the school understand what it means 'to get better' (progression) in the subject and does the school give meaningful attention to all categories of progression in English? Is the scope commensurate with that outlined in the National Curriculum?
Curriculum Intent and curriculum impact questions

Inspectors check how schools help learners remember English. They assess curriculum design and teaching (Smith, 2020). Inspectors seek evidence of spaced practice and retrieval (Jones, 2018). Schools must show their English curriculum builds memory through planned lessons (Brown, 2022). Lessons should link new learning to what learners already know (Lee, 2023).

The curriculum is planned so that essential knowledge is prioritised. For instance, more time may be spent on it, including time checking it has been embedded. This knowledge is introduced sequentially and revisited so it can be memorised. See 2a to 2d for details of this component knowledge.
This requires learners to receive information in manageable chunks. For example, in phonics sessions, learners are given daily opportunities to practise using and applying their learning. They may be asked to read and write graphemes, words or sentences using taught GPCs.
NB: In upper KS2, knowledge is built more cumulatively (less linear) through links and connections. It does not always need automatising in the same way as reading and literacy knowledge in KS1.
Show me which bits of your curriculum (like concepts, ideas, vocabulary, etc.) are really crucial to re-visit so that they are able to build further knowledge.
Curriculum Intent and curriculum impact questions
Ehri (2005) shows that systematic phonics improves early reading. Schools build reading skills alongside comprehension. Graham and Perrin (2007) suggest demonstrations are needed for complex writing progression.
Inspectors check if learners meet expectations, especially struggling ones. They seek evidence teachers use cognitive load theory (Sweller, 1988). Show how sequencing builds knowledge. Ensure phonics supports analytical writing (Christodoulou, 2017; Rose & Christakis, 2009).
Schools must show how they address common English errors. Learners may decode but not understand text (Cain & Oakhill, 2011). Support creative learners who need better technical skills (Bereiter & Scardamalia, 1987). Inspectors may ask about support, curriculum changes, and programmes. How teachers check learners' readiness for reading may also be explored (Fisher & Frey, 2012). Ensure learners use grammar well in all subjects (Abbott, 2003).
Subject leaders: document concept development from early years outcomes to key stage outcomes for Ofsted. Explain your curriculum sequence rationale to teachers. Make sure teachers understand topic order, and how it helps long-term learner learning (Wiliam, 2011; Christodoulou, 2014; Counsell, 2018).
Rosenshine (2012) highlights retrieval practice and spaced repetition. OFSTED inspectors often check for these strategies. Teachers, show how learners retain knowledge across lessons. Use starters, knowledge organisers, or low-stakes tests. Inspectors may ask learners about past learning. Integrate regular review into daily lessons.
When inspectors ask questions, discuss learning, not just teaching. Show how learners’ understanding grows and give evidence of their progress. Practice key concepts with clear words, (Wiliam, 2011). Ensure support staff know the curriculum, (Hattie, 2012) as inspectors may talk to them.
OFSTED adapts questions to suit each subject. In maths, inspectors check number fluency (Sweller, 1988). They see if learners build on prior knowledge. Science inspections focus on practical work. Inspectors check methods understanding. History inspections check timelines and source analysis (Wineburg, 2001).
Subject leaders, be ready for inspectors' questions about learning sequences. In modern languages, they may ask how phonics supports pronunciation (Smith, 2003). Inspectors also check vocabulary building across years (Jones, 2010). Design and technology will focus on applying knowledge and skill development (Brown, 2015). Maths checks progress from objects to abstract ideas (Davis, 2020).
Track learner progress and find core concepts (Meyer & Land, 2003). Assessments should show real learning, not just recall. Explain how your curriculum addresses typical subject errors (Wiliam, 2011; Black & Wiliam, 1998).
OFSTED inspections start with a 30-minute chat between inspectors and subject leaders. (Ofsted, past and present). This chat covers curriculum intent, how it's done, and tracking learner progress. Inspectors will ask about sequencing, assessment, and how subjects help learners develop generally (Ofsted, past and present).
Inspectors watch lessons for 20-30 minutes. They observe teaching, check learner work, and ask learners about understanding. Inspectors collect data on curriculum impact; they do not grade individual lessons (Ofsted, 2024).
Inspectors check assessments and curriculum, such as work samples. They briefly talk to teachers to clarify observations. Subject leaders, show curriculum progression in your documentation. Have ready examples of systematic learner knowledge and skill development.
An Ofsted deep dive is a focussed evaluation of a specific subject to assess the quality of education. It involves inspectors talking to subject leaders, visiting lessons, looking at work, and speaking to learners. The goal is to see how well the curriculum is organised and if learners are remembering what they have been taught.
Teachers prepare by ensuring they can explain why specific topics are taught in a particular order. It is helpful to have examples of how prior learning supports new concepts and how the school supports learners who fall behind. Practical evidence from workbooks and conversations with learners forms the basis of the evaluation.
Learners grasp new ideas best when they link them to current knowledge. Inspectors seek a sequence that builds on what learners know, as suggested by researchers like (researcher names, dates). This logical path helps learners practise skills without being overwhelmed.
Schools often focus on lessons, not the whole learning journey. Subject leaders may find explaining curriculum rationale and impact hard. The planned curriculum may not match learner knowledge (Wiliam, 2018; Christodoulou, 2014).
Inspectors often ask how the curriculum remains ambitious for learners with special educational needs and disabilities. They want to see how teachers adapt their delivery to ensure these learners can access the same core knowledge as their peers. You might be asked to show how specific scaffolds or interventions help SEND learners make progress toward the same endpoints.
Early reading is considered the bedrock of the entire curriculum, so inspectors prioritise checking how well phonics is taught from the start. They want to ensure that the youngest learners are gaining the decoding skills needed to become fluent readers. Inspectors will look at how the school identifies children at risk of falling behind and what immediate support is provided to help them catch up.
OFSTED reviews curriculums (intent, implementation, impact) using varied evidence. Inspectors check planning, records, and learners' work, noting knowledge gains. They value learners' cognitive development over task completion (Ofsted, ongoing). OFSTED seeks proof that learners understand concepts better (Ofsted, ongoing).
Documentation clearly shows each learner's progress. Inspectors require organised proof of curriculum plans, linking prior knowledge to new concepts. Examples show teachers correcting mistakes and adapting lessons (Hattie, 2012). Presenting work over time best proves learner progress (Wiliam, 2011; Black & Wiliam, 1998).
Evidence should reflect actual lessons for inspectors. Quality triumphs over quantity for Ofsted reviews. Demonstrate curriculum impact through real-world learner examples. Inspectors appreciate honest discussions on challenges, showing progress (Wiliam, 2018).
Research (Robinson & Timperley, 2007; Stoll et al., 2006) shows that prioritising evidence helps schools improve. Assess your school using eight areas and 40 indicators. This pinpoints strengths and reveals key areas for development (Chapman et al., 2016; Fullan, 2011). Use this data to make informed choices about school improvement (Levin, 2010).
