Pupils who attend Mynydd Haf school respond well to the supportive and nurturing environment. A majority of pupils make suitable progress during their time at the school accessing a range of learning experiences that reflect the wide range of pupils’ needs, abilities, and interests well. However, due to substantial shortcomings in inspection area 3, teaching and learning experiences and inspection area 4, care, support and guidance, pupil progress is limited in important areas. Most pupils make appropriate progress in their communication and social skills. As they develop their confidence, they build on these skills and benefit from a range of off‑site activities to support their learning. However, the teaching of personal, social and health education curriculum remains too variable across the school. Over time, many pupils improve their academic skills suitably allowing them to access a range of appropriate qualifications and accreditation. This supports pupils’ aspirations for post school destinations to college, further training or employment well . Leaders promote a supportive and nurturing ethos and a strong sense of belonging to the school community. Throughout the COVID-19 pandemic, they provided high levels of stability for many of their pupils. Currently the ability of leaders to plan for improvements at the school is underdeveloped. As a result, quality assurance and improvement planning processes are inconsistent. The school does not fully comply with the Independent School Standards (Wales) Regulations 2003. Shortcomings in pupils' progress in learning, as well as the safety and well-being of pupils, is inadequate and a cause for concern. Given the non-compliance with the Independent School Standards (Wales) Regulations 2003, the Welsh Government may wish to recommend formally to the school that it should not accept new pupils at the school until these matters have been addressed.
