What Ofsted said
From the inspection on 22 November 2023
Pupils enjoy studying a broad curriculum with an emphasis on learning modern foreign languages. Pupils who speak English as an additional language continue learning their first language while studying other languages, such as French, Arabic, Chinese and Spanish. Pupils who speak English as an additional language get personalised support to develop their English language skills. Students in Grades 11 and 12 like the small size of the sixth form and the close attention they get from teachers in lessons. Pupils are encouraged to respect the many different backgrounds, faiths and beliefs of pupils at the school. Through events such as the 'Cherry Blossom Festival' and the 'Arabic Night' they learn about the cultures of others. The school makes sure that new pupils settle in quickly and feel welcome when they join. Staff listen and help pupils should any concerns arise. 'Speak out' sessions in form time each week give pupils the opportunity to discuss any concerns or to ask questions about issues, such as healthy relationships. Pupils are sensibly behaved and respectful towards staff and other pupils.
What the school should improve
- Staff do not routinely check in class what pupils know and remember, particularly in the secondary phase. This means that some gaps in knowledge are not identified and addressed. On occasion, the tasks that pupils are set are not carefully chosen for pupils' individual needs. The school should ensure that the tasks are well chosen to support pupils to learn the intended curriculum and that any gaps in pupils' knowledge are picked up quickly and addressed.
- At times, there is a lack of rigour in the way that leaders and the proprietor body check and evaluate aspects of the school's work. This means that sometimes, leaders do not ensure and assure themselves that the school's work follows what is intended. The school should ensure that oversight of the school's effectiveness is strengthened.
