Pupils have been failed for far too long at The De La Salle Academy. Leaders and trustees have not done enough to improve the school. Across the school, pupils’ achievement is exceptionally low in too many subjects. Current pupils have extremely wide gaps in their knowledge and understanding. Leaders and teachers do not expect enough from pupils. Pupils have very weak mathematical skills. In 2019, pupils’ attainment in mathematics declined to an all-time low. Current pupils are not faring any better. Owing to financial issues, too many pupils have experienced a very narrow curriculum. Although art, drama, geography and technology have now been reintroduced, many pupils missed out on learning these subjects from Year 7. Music is still not offered. There is a deep-rooted culture of poor attendance, particularly for disadvantaged pupils and pupils with special educational needs and/or disabilities (SEND). This prevents these pupils from learning and achieving well. Pupils’ behaviour has improved over time. Leaders have successfully established a culture where pupils can now learn. Relationships between teachers and pupils are positive. However, some pupils do not behave well at social times. Pupils told us that bullying is dealt with effectively and that they feel safe. Pupils appreciate the extensive range of extra-curricular opportunities on offer, including sports, chess and the cadets. They enjoy taking part in charity work and educational visits. Pupils’ personal development is very strong.
