Ysgol Abercaseg provides a stimulating curriculum that prioritises pupils' development as proud, responsible and ambitious citizens. They offer meaningful learning experiences that foster strong links between the school, their community and the Welsh language. Teachers plan sessions that provide a challenge in pupils' learning and build on their interests skilfully. They use the local environment creatively to broaden pupils' horizons and to deepen their awareness of their identity. Pupils take an active part in community activities and show obvious pride as they contribute enthusiastically to the life of the village. Most pupils make sound progress in their literacy, numeracy and digital skills. They develop as enthusiastic speakers and confident readers who communicate intelligently and discuss their learning effectively. Pupils' writing skills develop skilfully, with the older pupils writing maturely for different purposes. Most pupils develop their mathematics and digital skills purposefully in interesting activities. Purposeful opportunities are provided for them to develop their thinking skills independently in activities that encourage them to solve problems and overcome difficulties in their learning. On the whole, teachers use effective teaching methods that encourage pupils to work together successfully. They question in detail and challenge pupils to think more deeply about their learning. Pupils respond positively to support and show robust attitudes to their learning. However, at times, staff over-lead pupils' learning which reduces the opportunities for them to learn independently. Staff promote pupils’ care and well-being extremely effectively. They forge a positive working relationships with pupils, which supports learning successfully. This contributes effectively to the positive behaviour of most pupils and fosters healthy attitudes to learning. The governing body provides relevant support and challenge to leaders in a constructive manner. The school’s self-evaluation and improvement planning processes are robust, but leaders do not always ensure that self-evaluation procedures are as thorough across the whole federation.
