A questionnaire to assess views about spiritual development was completed by 112 of the 174 head teachers of church primary schools in Wales. The findings indicated that despite the seemingly ambiguous nature of the term "spiritual development", head teachers had clear views about its meaning. While most head teachers emphasised the need for pupils to engage in their own personal spiritual search, their views differed in the extent to which they felt that promoting spiritual development meant encouraging pupils to adopt Christian beliefs. While the age and sex of head teachers was found to have no significant impact on their views; and the location and category of the school for which head teachers were responsible had only a limited impact on their view, the language of the school and the religiosity of the head teacher had a considerable impact on views regarding these matters.
