This teacher knowledge study follows Benita Dalton as she moves from c
ontext to context as a pre-service teacher, as a substitute and long-t
erm replacement teacher, and as a beginning teacher placed in two scho
ol contexts. Situating Benita in numerous settings illuminates the way
s in which the particularities of placement influence what is availabl
e for teachers to come to know, what is held up as 'good teaching,' an
d who is authorized to produce knowledge. A case is built that gives v
alue to teachers' knowing based on the narrative authority of their pe
rsonal practical knowledge as expressed in their knowledge communities
