Ysgol Llanhari is a caring and inclusive community that promotes a strong sense of belonging. In learning sessions, nearly all teachers foster positive working relationships with pupils. As a result of the valuable pastoral care and the effective health and well-being provision, most pupils feel safe at school. Their behaviour is extremely polite and respectful. A strong feature is pupils’ willingness to work and discuss with their peers, with many demonstrating very positive attitudes to learning. Many pupils across the age range make the expected progress, which a few making strong progress in their lessons and over time. Pupils benefit from valuable opportunities to practise and develop their literacy skills, particularly their speaking and listening skills. There are also purposeful opportunities for pupils to develop their reading and writing skills while at school. However, although opportunities to develop pupils’ numeracy and digital skills are planned across the curriculum, provision has not been co-ordinated strategically enough to ensure that pupils develop these skills progressively during their time at the school. Staff provide valuable learning activities and experiences that support pupils to settle quickly and contribute fully to school life. There is beneficial co-operation with partner schools, for example in promoting the status of international languages as part of the curriculum. There are also purposeful opportunities for pupils to contribute to various committees and to take part in a wide range of extra-curricular activities and trips. The school develops a culture of professional learning successfully. A clear focus on teaching and learning has a positive effect on what happens in lessons. As a result, nearly all teachers ensure a supportive learning environment and foster positive working relationships with pupils. Many teachers plan purposeful activities, provide constructive verbal feedback and ask an appropriate combination of questions to check pupils’ knowledge and understanding. The headteacher and leadership team work closely together and share their ambitious vision, which is based firmly on the values of Community, Welshness and Progress. Although leaders have suitable processes for self-evaluating provision and planning for improvement, they do not always focus sufficiently on the effect of their work on pupils’ outcomes.
