Donhead Preparatory School is a Roman Catholic independent school for boys, ages 4 to 11, in the trusteeship of the Society of Jesus.

The school exists primarily to provide a Jesuit education for children of the Catholic community. Once it has met its historical and current obligation to boys of the Catholic community, Donhead Preparatory School welcomes those who support the religious ethos of the school.

The colour of the uniform has been described as 'Royal blue', but it was a distinctly lighter shade than what we are familiar with nowadays - one reason for this being that the original colour was impossible to get during World War II.
