What Estyn said

Estyn's report on its October 2022 inspection summarises Treffos School like this:

"Treffos School is a nurturing environment and instils its pupils with a love of learning. Its rural location complements its vision to bond learning with the real-world through a thematic curriculum and extensive opportunities for learning outdoors. It is a strong community which unites pupils, parents and staff. Nearly all pupils at the school are confident and inquisitive. They feel both happy and safe. Nearly all pupils make strong progress from their starting points, particularly in developing their literacy, numeracy and speaking skills. Pupils know they will be listened to and that they are valued. They are excited to learn and demonstrate a strong sense of independence and responsibility. The ‘Treffos Values’ are embedded into the pupils’ culture and their behaviour is mostly exemplary."

"Teachers model a curiosity about the world well and work passionately to create an environment where every pupil can thrive. Teachers promote learning through a wide range of interesting activities and in many different locations both on and off site. All staff know the pupils extremely well and the provision for each individual pupil is regularly reviewed and adjusted accordingly. Leaders at the school are passionate, capable, and highly accessible. They are ambitious for all pupils and have high expectations of their staff. They took decisive steps when the pandemic arrived ensuing that their pupils continued to receive the same high standard of education and care. Leaders collaborate suitably to operate the school and have taken steps to introduce greater strategic oversight of policy, practice and the curriculum through the appointment of a critical friend. Treffos School meets all the Independent School Standards (Wales) Regulations 2003, needed to maintain registration. Compliance with the regulations for registration Independent school inspections are governed by the Education Act 2002 and related regulations: the Independent School Standards (Wales) Regulations 2003."

"These regulations require an independent school to meet an appropriate standard in the following areas: The quality of education provided by the school The school meets the regulatory requirements for this standard. The spiritual, moral, social and cultural development of pupils The school meets the regulatory requirements for this standard. Welfare, health and safety of pupils The school meets the regulatory requirements for this standard.

Premises of and boarding accommodation at schools The school meets the regulatory requirements for this standard. The provision of information The school meets the regulatory requirements for this standard. The manner in which complaints are to be handled The school meets the regulatory requirements for this standard."

Estyn made 3 recommendations: (1) Ensure that school policies are updated regularly to have regard to the latest Welsh Government guidance and that staff practice reflects policy; (2) Strengthen and embed the school’s quality assurance processes; (3) Clarify the responsibilities and priorities of leaders across the school.
