This paper reconsiders Benner's book From Novice to Expert, in which t
he expert is portrayed as a reflective practitioner who works intuitiv
ely, drawing almost unconsciously on a repertoire of context-specific
paradigm cases. In the light of more recent writings on informal, prac
tice-based theory, it is suggested that there is a sixth level beyond
expertise which is characterized by mindful practice and informal theo
ry building. At this level, the practitioner constructs informal theor
y out of practice, applies that theory back into practice, and reflexi
vely modifies the theory as a result of the changed clinical situation
. Seen in this way, theory and practice are two parts of the same proc
ess, and the theory-practice gap is closed.
