The units of work that we have developed for each year group are based on Chris Quigley’s Essentials Curriculum. This is a curriculum that encourages a mastery of learning. In practice, what this means is that lessons are designed carefully to allow the introduction and revisiting of facts, skills and concepts in a carefully thought out sequence. We use Milestones to assess where children are according to age-related expectations. Our assessment procedures allow us to understand the depth of children’s learning not simply what they have covered and then retained in one moment in time.
