This article used narrative accounts by social work practitioners to i
dentify the evidence they used to decide whether work had ''gone well.
'' Evaluation strategies were constructed from a ''game plan,'' the su
ccess of which was viewed as partly contingent on the untoward operati
on of ''sheer luck.'' The social workers judged their practice accordi
ng to whether their work produced emotional awards; the case was ''mov
ing''; intervention won steady, incremental change; practice was accom
plished without inflicting harm through the operations of the welfare
system; and confirming evidence was available from fellow professional
s. These practitioners were preoccupied with causes and reasons for ou
tcomes of their work, held strongly worked views about the complexity
and ambiguity of social work evidence, and were acutely aware of the c
onstant interplay of knowing and feeling in practice. practitioners' e
xisting evaluation practices provide the starting point from which soc
ial workers can begin to develop a method of practice evaluation that
avoids a decontextualized imposition of ideal models. To move forward
the debate about evidence-based practice, social workers need to refle
ct on the significance of practitioners' day-to-day evaluating.
