At St John’s we aim to provide a stimulating environment so that each boy can develop an enthusiastic and self-disciplined approach to learning and life. Extra-curricular and enrichment activities also provide many opportunities for him to shine individually and within a group. As part of this aim we organise a number of outings for each year group, or invite visiting speakers into school. These visits and talks provide stimulating opportunities for learning.
