In this paper, I use Polsby's (1968) theory of institutionalization to
study change in the career patterns of state legislative speakers. I
find that in certain ways leadership is institutionalizing. Most speak
ers today had previous leadership experience, and in a majority of cha
mbers there is a specific career path to the speakership. Both previou
s experience and career path are indicators of institutionalization. H
owever, the career path in virtually all chambers is flexible. Further
, the more professionalized legislatures are more likely to lack a spe
cific career path than are less professionalized institutions. These f
indings add to the literature that suggest that state legislatures do
not show a consistent pattern of institutionalization.
