The school is a Welsh community whose core values are based on mutual respect, honesty and concern for others. The focus is on achieving each pupil's potential and every effort is made to attain the highest standards of academic achievement for each individual. These firm foundations enable the pupils to widen their horizons so that each one can become a responsible and active citizen.
Welsh is the language used in the daily life of the school and in the majority of lessons. Sustaining a Welsh ethos within the school, the local community and beyond is a central part of the school's work.
- Another cornerstone of the school's work and mission is the pupils' moral, spiritual and physical development.
- The school upholds the highest standards of behaviour and this is reflected in the pupils' good behaviour over the years.
- The school has clear and high expectations and the pupils and families recognize these and seek to support them.
- Supporting the work of charitable and humanitarian causes is a prominent part of the work and tradition of Penweddig.
