It is now generally accepted that schools differ in their effectivenes
s as places of learning. There is a considerable amount of evidence ab
out the characteristics of effective schools but little knowledge of h
ow they can be developed. Accumulated evidence from Office for Standar
ds in Education (OFSTED) inspections, carried out under the provisions
of section 9 of the Education Act 1992, provides the potential for na
tional comparisons of different types of school across local authoriti
es. Findings based on an analysis of the data suggest that, in the jud
gement of school inspectors based on OFSTED criteria, Catholic seconda
ry schools provide a statistically significant higher standard and qua
lity of education than others in the maintained sector. Possible socio
logical reasons for the findings and their contribution to the 'effect
ive schools' debate are discussed.
