Ysgol Gymraeg Nant Gwenlli, which was established in September 2021, is a successful learning community that celebrates pupils’ Welshness, courtesy and respect exceptionally well. The acting headteacher, with the support of the leadership team, provides clear and wise leadership and respects the efforts of everyone who contributes to pupils’ well-rounded education. Staff are committed to ensuring high quality care and well-being for pupils across the school in a homely and supportive learning environment. This has a strong influence on pupils’ attitudes towards each other. Staff model the Welsh language correctly and enthusiastically, which has a positive effect on pupils’ oral skills from a young age. As a result, pupils’ use of, and pride in, the Welsh language is a strong feature. Staff work together successfully to plan a range of stimulating learning and play experiences for pupils. The co-operation between the school’s staff and staff from a nearby school, which is led by the acting headteacher, and staff from schools in the cluster, has a positive influence on pupils’ education. Most pupils develop knowledge, understanding and skills that are appropriate for their starting points and stage of development successfully. For example, most develop their Welsh oral and reading skills skilfully and contribute purposefully to discussions, by expressing their opinions clearly and maturely. Teachers provide purposeful opportunities for pupils to learn independently, which include valuable sessions for them to work together to solve challenges and complete projects. Provision for supporting the learning skills of pupils with additional learning needs (ALN) is purposeful. As a result, they make good progress over time against their targets and previous achievements. In the best practices, staff’s questioning methods and oral feedback provide pupils with valuable support to improve their learning. However, these effective practices are not consistent across the school. The school’s self-evaluation and quality assurance arrangements are thorough. Members of the governing body support the acting headteacher and staff purposefully. They have a sound awareness of the school’s strengths and priorities for improvement and provide an appropriate balance of support and challenge.
