At a time when almost every area of social policy in the UK is undergo
ing a period of radical 'top-down' reform, several writers have identi
fied a key role for ethnographic research, which examines the social p
rocesses through which macro changes in structure and funding are expe
rienced and reconstructed at the micro level. This paper presents one
such study. Empirical data are used to chart the complex, interconnect
ed processes through which national reforms helped destroy the previou
s balance of micro-political power in a school, ultimately leading to
fundamental changes in policy and practice in a previously 'progressiv
e' comprehensive. The school's fate highlights the importance of micro
-political power, but also compels us to consider the wider forces at
work on the school. The teachers' micro-political struggles make sense
only when viewed against the backdrop of sweeping conservative reform
at the macro level.
