Ysgol Llanddulas is a friendly, welcoming community with clear values and a strong ethos. Staff build strong relationships with pupils that help them to feel secure and confident in their care. They involve pupils in decisions about what and how they learn and enable them to play an active role in school life and in their local community. As a result, nearly all pupils feel invested in their school, behave well and show positive attitudes towards their learning. Teachers plan for the development of pupils’ literacy, numeracy and digital skills successfully. However, provision to develop pupils’ use of spoken Welsh is less effective. Teachers provide a broad range of engaging learning experiences that sustain the interest of nearly all pupils well. They make beneficial use of many practical activities to develop pupils’ initiative and creativity. Most pupils tackle tasks with independence and show self-reliance in their learning. Teaching assistants provide valuable additional support where needed to bolster pupils’ skills and to nurture their well-being. However, teachers do not always challenge more able pupils to apply their knowledge and skills in contexts that stretch their ability fully. The school makes worthwhile use of visits and visitors and an extensive variety of after school clubs to enhance pupils’ enjoyment of their learning beneficially. Leaders know their school well. They monitor pupils’ progress thoroughly and evaluate the quality of provision robustly. They use their findings to bring about improvements in specific areas successfully, such as to improve the quality of pupils’ writing. Leaders generate a strong shared commitment across the staff team. They make strategic use of professional development to build capacity and foster collaboration within and beyond the school. This supports staff to make changes confidently, such as to enhance pupils’ role in developing the school’s curriculum. Governors support the work of the school purposefully. They provide constructive challenge to leaders and monitor the school’s finances carefully. Leaders and governors sustain beneficial relationships with parents and with community partners such as the local church and pre-school. These partnerships strengthen the school’s role in the life of the community it serves.
