Rigorous assessment is a key feature of student life at BDA. Teachers mark students’ work every two weeks, checking progress and providing formative feedback. Students can expect to be formally assessed every six weeks, receiving a National Curriculum level (KS3), GCSE grade (KS4) or A Level grade (KS5). Rank orders, showing attainment across all subjects, are displayed in corridors and classes are set according to ability, with frequent opportunity for transition.

In key stages 4 and 5 assertive mentoring pairs students with a specific teacher who will track progress throughout the year, meeting regularly to offer targeted intervention.
