Estyn's report on its November 2025 inspection summarises Ysgol Gymraeg Treganna like this:

"Ysgol Treganna is a caring and inclusive community in which pupils feel happy and safe. The clear vision of 'Tri Treganna' is a robust basis for the school’s ethos and has a positive influence on pupils’ wellbeing and learning. As a result of the headteacher’s effective leadership and staff’s successful cooperation, pupils enjoy rich learning experiences that foster their confidence and social and emotional skills. Provision for wellbeing is particularly strong. The Cwtsh and Nyth provisions offer sensitive support to pupils, and the 'five purposes of wellbeing' approach supports pupils and their families extremely effectively. These opportunities foster self-discipline and positive attitudes towards learning in most pupils."

"The school uses a wide range of information to identify improvement priorities, and staff and pupils contribute to this work meaningfully. The sensible distribution of responsibilities promotes robust provision, and grants are used appropriately to ensure equal experiences for all pupils. The curriculum is broad and intertwines with the local community successfully. There are rich opportunities to learn about Welsh identity and the wider world, and pupils show respect for others and an understanding of diverse values. Across the school, robust teaching fosters positive attitudes. Most pupils develop literacy, numeracy, digital and creative skills successfully from their starting points."

"Staff promote and foster pride in the Welsh language purposefully, by building most pupils’ confidence to use the language in different contexts. The youngest pupils develop their oral skills in stimulating learning environments, and by year 6, most write skilfully across the curriculum. Most pupils' mathematical understanding develops robustly, with appropriate opportunities to apply numeracy skills across the curriculum. Staff identify pupils' individual needs successfully and respond promptly. In doing so, most pupils with additional learning needs (ALN) and those from low-income households make good progress."

Estyn made 1 recommendation: (1) Ensure that the most effective teaching practices are applied consistently across the school.
