Since the Anglican Church in England and Wales began to build schools long before the state developed machinery to do so, around a quarter of all primary schools remain connected with the Anglican Church. The church school inspection system maintains that Anglican schools have a distinctive ethos. The Student Voice Project argues that school ethos is generated by the implicit collective values, beliefs and behaviours of the students, and was designed to give explicit voice to the students in response to six specific areas of school life identified by the Anglican school inspection criteria as relevant to school ethos. Drawing on data provide by 8,111 year-five and year-six students attending Church in Wales primary schools, the present study reports on the six ethos measures and on significant differences reported by female and male students, and by year-five and year-six students.
