Superintendent turnover can hurt reform efforts and
district improvement, but little research has examined what factors
predict superintendent exits in a large sample. This study
identifies factors contributing to superintendent exits in California by
matching original superintendent and school board survey data with
administrative data and information hand-collected from news sources on
why superintendents left and where they went. Among 215 superintendents
studied beginning in 2006, 45% turned over within 3 years. Using
multinomial logistic regression to separate retirements from other types
of turnover, we find that while age is the primary driver of retirements,
other factors, such as school board members’ assessments of how well the
board functions or whether the superintendent was hired from within the
district, are highly predictive of non-retirement exits. District test
score growth, however, is uncorrelated. Moreover, we find that
superintendents who move migrate toward larger, higher-paying districts in more
urban locations.

The story of school superintendent turnover is a
well-known one: energetic new leader assumes position with plans for
revitalization, only to clash with a dysfunctional school board
or impatient community and move on to greener pastures before the plan can
be fully carried out, leaving the district once again searching for the
next great leader bearing the requisite comprehensive reform plan.
High-profile examples abound of reform-minded superintendents whose
tenures saw gains in student test scores but whose time in office was cut short
by public
pressure and tumultuous school board relations:
Arlene Ackerman in San Francisco, John Thompson in Pittsburgh, Rudy Crew
in Miami-Dade County, Stan Paz in Tucson (Buchanan, 2006; Cave &
Almanzar, 2008). Often, the story goes, ousted superintendents move on to
other districts; Ackerman moved on to—and was then pushed out
of—Philadelphia, Thompson was terminated after a year in Clayton County
(Georgia) Schools, Crew had already been chancellor 2of New York City’s public
school system, Paz had served in El Paso. This shuffling
of superintendents through school districts creates a kind of “revolving
door” in the superintendent’s office (Natkin et al., 2002), as witnessed
by Kelvin Adams becoming St. Louis Public Schools’ eighth superintendent
in five years in 2008 or John Covington becoming Kansas City Missouri
School District’s twenty-fifth superintendent in forty years the next year
(Taylor, 2008).
With chronic turnover come expectations that
turnover is inevitable, making the superintendent turnover story one of
short-term focus with insufficient investment in long-range vision and
infrastructure (Buchanan, 2006).
The trouble with this story is that it may not be
true, at least not for the typical public school district. The
popular conception of the modern superintendent as a chronic mover
in continual public disharmony with a conflict-ridden school board is one
developed from media portrayals of prominent cases in the nation’s largest
urban districts, whose experiences may not be representative of those of
the suburban and rural districts that make up the majority of local school
governments—or even of the average urban district. As Natkin et al. (2002)
argue, this potentially errant popular understanding has consequences for
both for the practice of superintendents—who become reluctant to take on
major reform efforts—and the responsiveness of principals and teachers,
who may adopt a “this too shall pass” approach to
superintendents’ priorities and directives.
Unfortunately, there is little systematic evidence
with which to question this common conception or issues of superintendent
turnover more broadly, a puzzling situation given the importance ascribed
to superintendents in leading district improvement. As the
school district’s “chief executive,” superintendents oversee key aspects
of district operations.
Research
suggests that successful execution of central management functions such as
staff recruitment, financial management, leadership of instruction, and
strategic planning helps create positive learning environments within
schools, which may indirectly impact student achievement (Alsbury,
2008; Byrd, Drews, & Johnson, 2006; Petersen, 2002). Because
instability in the superintendent’s office disrupts these management
functions, superintendent turnover may negatively impact district
performance, at least in the short term; research concluding that successful
systemic school reforms take five or more years of a superintendent’s
focus suggests that negative impacts of turnover could be felt even longer
(Fullan & Stiegelbauer, 1991). The
loss of a superintendent may also negatively affect staff morale and
satisfaction (Alsbury, 2008), which could have “trickle-down” effects on
principal and teacher turnover and performance.
The importance of the district superintendent and
the potential consequences of superintendent exits make understanding the
factors that drive superintendent turnover a key topic for empirical
research. Lamentably, however, superintendent turnover lacks
a well developed research base (Natkin et al., 2002).
Existing research has primarily taken the form
of qualitative explorations of turnover motivations through case studies
and interviews with superintendents. Few studies have focused on
empirically testing the relative strength of associations between
superintendent turnover and characteristics of the superintendents,
districts, and school boards with whom they work. Moreover, studies
have not examined how these predictors might vary with the type of
turnover (e.g., retirement, resignation).
To address these gaps in the literature, this study
pulls together existing research on superintendent turnover alongside a
complementary—and perhaps more well-developed—stream of research on
turnover among city managers to identify potential drivers of
superintendents’ decisions to leave. Research on city managers
is applicable because the job of the city manager shares important
characteristics (e.g., managing a complex organization, working closely with an
elected board) with that of the school superintendent. We develop a simple
labor market framework in which a superintendent’s continued employment in
a district is determined by employment decisions made by both
superintendents and their school boards, then draw on the superintendent
and city manager turnover research to identify four classes of factors
that contribute to those decisions: characteristics of the district,
school board, and superintendent himself or herself, plus superintendent
job performance.
To test the expectations our framework develops, we
draw on original matched survey data from superintendents and school board
members in more than 100 randomly chosen California school districts,
which run the gamut from large urban bureaucracies to small
rural districts with few schools, to investigate these factors in depth.
These survey data are supplemented both with administrative data from the
California Department of Education (CDE) and the National Center for
Education Statistics’ Common Core of Data (CCD) and with additional
information on superintendent turnover culled from newspapers and other public sources.
Employing logistic and multinomial logit regression to model
superintendents’ probabilities of turning over within a three-year window,
we examine a variety of potential contributors to superintendent turnover,
with attention to the differences between retirement and other types of
exits.

Discussion and Conclusions
This study makes several contributions.
First, it introduces the idea of
considering superintendent turnover in the context of the broader superintendent
labor market—in which decisions made both by school boards and
superintendents are important—allowing for consideration of a broader set
of factors than in most prior literature on the topic.
Second, it draws on insights from a longer
public administration literature on city manager turnover to help frame
turnover among superintendents, whose positions are similar to those of city
managers along key dimensions.
Third, it evaluates the contributions of factors
prior superintendent turnover research has suggested as important, such as
the role of the school board, alongside factors that have previously gone
unexamined, such as evaluations of superintendent performance.
Fourth, it separates retirements from other kinds
of moves empirically to provide a more precise assessment of how different
factors contribute differentially to those turnover decisions.
Finally, it sheds light on patterns in
superintendents’ moves across districts, pointing toward a potentially
fruitful area for further empirical inquiry.
The results paint a complex picture of
superintendent turnover and one that questions some commonly held
assumptions. We introduced this study with the idea that much of what
we know collectively about superintendent turnover comes from cases of
turnover in the largest school districts (e.g., Buchanan, 2006).
Considered alongside a representative set of
school districts of other sizes, however, those districts appear atypical;
three-year superintendent turnover
rates in the top decile of enrollment size are approximately 30 percentage
points higher than in the rest of the distribution, highlighting the
need to expand our frame beyond case studies of urban districts if we wish
to understand superintendent turnover more generally. Even controlling for district size and urban status,
superintendent turnover is associated with other markers of a challenging
district environment, such as a greater instance of student poverty.
The inverse association between wealth and turnover—observed in turnover
studies for other positions in school systems, including school
administrators (e.g., Gates et al., 2006)—is potentially troubling,
showing that turnover is higher in the districts that potentially might
benefit most from stability at the top and the opportunities for sustained
reform that come with it (McAdams, 1997).
Our results also question the assumption that
community dissatisfaction—a dominant construct in this literature since
Iannaccone and Lutz (1970)—plays a central role in most exits.
In our data, clear
terminations of superintendents are very rare, though we do not discount
the likelihood that some of the exits we coded as resignations were
instances of superintendents being pushed out by dissatisfied school
boards, which may not have been evident from the sources we consulted.
Also, we do find that superintendents
leave more often when the school board views their job performance less
positively. Still, consistent with
other studies concluding that most superintendent turnover is in fact
apolitical (Alsbury, 2003), we both document the importance of retirement
as a frequent source of turnover (more than a third of those we observe) and
provide evidence that superintendents often move for career advancement.
Despite the apparent challenges associated with positions in larger urban
districts that later induce high turnover, superintendents tend to move towards positions in those districts,
perhaps because such moves increase pay and prestige (Parker, 1996).
Similar patterns regarding moves for professional advancement have been
observed among city managers (DeHoog & Whitaker, 1990; Glass et al.,
2000).
The
importance of career advancement as a driver of superintendent turnover is
consistent with our argument that turnover should be considered as an outcome
in a labor market in which better external opportunities can attract
superintendents away from their positions.
The
pronounced trend for movers away from rural districts raises the question of
whether such districts are used by some superintendents as “stepping
stones” to more desirable positions.
Studies have documented this phenomenon among other
public sector workers in rural areas, including police officers (Wood,
2001), city managers (Watson & Hassett, 2004), and
school administrators (Dlugosh, 1994). Although average turnover rates are not statistically higher
in rural districts, the trend we observe suggests that rural districts
have less success in hiring experienced superintendents than their more
urban counterparts when turnover occurs. It also illustrates that the “pull” of career advancement must be
considered alongside the “push” of difficulties in the current work
environment as an important contributor to superintendent exit.
Adding
further complexity, evidence suggests that these two forces can operate on the
same superintendent simultaneously. For example, even when a
superintendent move sends him or her 36to a larger district with better pay,
the superintendent often leaves behind a school board with whom the
working relationship was poor (Chance & Capps, 1992).
These
poor relationships with the board—pegged to board operational ineffectiveness
and conflict more generally—are important predictors of superintendent
exits in our study, echoing findings from prior work (e.g.,
Danzberger et al., 1992).
Although a key predictor, in most districts
both the school board and the superintendent rate the board as high-functioning
and their mutual relationship as positive in our survey data; for example,
the average response to the item rating the school board-superintendent
working relationship was 4.4 (on a 5-point scale) in the school board
survey data and 4.5 for the superintendents (see also Glass et al., 2000).
Unfortunately,
high-conflict school boards with poor superintendent relationships are more
likely in (already turnover-prone) large, low-income districts (Danzberger
et al., 1992; McCurdy, 1992; Grissom, 2010), compounding the likelihood
that superintendents (or the board) become dissatisfied with their current
employment situation and increasing the likelihood of turnover in those
districts (Whitaker & DeHoog, 1991). If board dysfunction
drives this sort of voluntary turnover, or if board dysfunction creates
dynamics that makes them more likely to push out superintendents
involuntarily, efforts to improve how well the school board works together
and with the superintendent via board training or professional development
may pave the way for greater leadership stability (Mountford, 2008;
Grissom, 2012).
Hiring
“homegrown” superintendents rather than seeking district leadership from
outside may also help counteract drivers of superintendent instability. Superintendents promoted from within
the district are much less likely to leave, perhaps because, as Carlson (1961)
found, they are more committed to the community. Yet Carlson (1961) also
found that leaders hired from inside the organization are oriented towards
maintenance of the status quo and are less likely to new policies that “prepare
the organization for new ways of functioning” (p. 226), which suggests
that increased leadership stability can come at the expense of district reform.
Underperforming school districts may in fact be
better off seeking innovative leaders from outside the district even if it
means a shorter tenure is likely.
The study faces a number of important limitations.
First, the data we used were drawn exclusively from California. While its
diversity and size—it educates one-eighth of the nation’s students—make
California a useful setting for this examination, they also set the state
apart.
School districts in California tend to be more
racially and economically heterogeneous and have less flexibility over
resource use than districts in other states. Though the structure
of superintendent and school board positions are similar to those
elsewhere, we cannot be sure that our results directly generalize outside
the state.
A second
limitation for the study is its inability to adequately tease apart voluntary
and involuntary superintendent turnover and the factors that
differentially predict them. In part, this was a sample
size problem; we identified too few instances of involuntary turnover to
examine it separately. This inability to identify cases, however, may have
reflected our data collection approach.
Involuntary
superintendent turnover can be a politicized, controversial affair, and
both participants and observers may have conflicting views of whether a
superintendent is being pushed out or is resigning for other reasons.
Formally, the superintendent may characterize a resignation as personal
(e.g., to spend more time with family) or as facilitating other
employment opportunities when it was, in fact, driven by board
disagreement or an inevitable firing. Calls to districts, news accounts,
or minutes from school board meetings may reflect only the formal story in
this case, distorting our attempt to categorize.
Future studies of superintendent
turnover might attempt to triangulate the reasons for turnover using a
combination of approaches, including surveys of multiple stakeholders, key
informant interviews, media accounts, and other sources. Such data would
allow deeper examination of our conceptual model.
Future analysis in this area would also benefit
from longitudinal data. The data employed here are cross-sectional, which
have little power to identify causal relationships. In a cross section, we
cannot be sure that the association between turnover and school board function,
for example, is not driven by some unobserved characteristic of the school
district (e.g., low social capital) that predicts both variables. Panel
data can facilitate more rigorous analytic approaches (e.g., district
fixed effects) that can help deal with such concerns. Data on
superintendent employment over time would also facilitate other modeling
approaches—i.e., survival analysis or a competing risks hazard model that
allows for different kinds of exit—with more power to uncover the
predictors of turnover at different stages in a superintendent’s tenure. Panel
data can also provide means for dealing with the kinds of endogeneity that
arise between turnover and variables such as salary. Though salary was a
component of our conceptual model, limitations on the empirical model
prevented us from treating it appropriately, though we do
uncover suggestive evidence from a descriptive relationship between salary
and mobility. Because salary is an
obvious potential policy lever districts may pull in attempting to prevent
superintendent turnover, future work that rigorously identifies the
salary-turnover relationship would make a useful contribution to the
literature.
Another
relationship for which this study only scratched the surface was that
between turnover and superintendent job performance. School
board members’ subjective evaluations of the superintendent’s performance
predicted turnover, but district performance did not. Perhaps superintendents are not held accountable for short-term
school district test performance, which may be appropriate if, as some
studies suggest, superintendents can have little effect on test scores
(Ehrenberg et al., 1988). In this case, better identification of the outcome
variables superintendents do affect would be a useful addition. In
addition, future studies should employ strategies to account for the
potential endogeneity that may arise if superintendent turnover
and district performance each predict one another.
Ultimately,
our analysis illustrates that superintendents exit positions for numerous reasons. As our
conceptual emphasis on the two-sided nature of turnover decisions in the
labor market predicts, some
turnover is driven by factors that inform school boards’ decisions
about future employment (e.g., superintendent performance) while other
turnover comes from superintendents’ decisions to leave, which is informed
by other factors (e.g., working conditions, external opportunities). Still
other turnover is the result of retirement decisions, which appear to be
primarily determined by age. Practically, school districts might use this results
to improve superintendent retention by focusing attention or resources on
its antecedents. For example, they might select candidates differently or
work to build supports for superintendents faced with increased
administrative complexity, such as that in unified school districts. From a
research perspective, the framework and results we present point towards
several new avenues for future work.
