This article describes a study of peer supervision framed within the c
ontext of a formal school board-sponsored program called Supervision f
or Growth (S4G). In the study I examined the collegial interactions of
4 teachers and their partners in 1 Canadian school and explored the e
ffects of collegiality on the teachers' work. Data for the study consi
sted of field notes and interview transcripts collected over a 5-month
period of participant observation. Results showed that the quality an
d quantity of collegial interactions between the 4 teachers and their
partners covered a broad spectrum-from frequent and productive to infr
equent and superficial. The kind of formality encouraged by the coachi
ng cycle in S4G was eschewed by all teachers in the study. Teachers di
d not see conferences, observations, and record keeping as essential t
o their daily practice. The principal's role in the process was genera
lly one of warm encouragement and helpfulness, rather than interventio
n Overall, teachers were more receptive to the general idea of helping
than to formal notions of coaching or supervision.
