A growing body of research has been documenting the pivotal role that philanthropic funding plays in advancing state and local charter school reform. However, there is little understanding of the geographic flow of these funding patterns and the market, policy, and organizational conditions that have concentrated funding in some clusters of states more than others. To address this limitation, we use descriptive cartography and quadratic assignment procedure (QAP) regression to analyze longitudinal funding data from 15 philanthropic foundations along with data related to the contexts of the states where grant recipients reside. We find that between 2009 and 2014, foundations were increasingly converging their funding flows to charter school organizations in select clusters of states as they shifted the concentration of funds away from individual charter schools to charter management organizations (CMOs) and advocacy organizations. A substantial portion of the variation in this interstate convergent grant funding was associated with previously established funding flows. However, the local market and policy contexts of states and certain forms of evidence of charter school effectiveness were also associated with interstate convergent funding. These findings point to the potential ways public policy and research can shape the flow of private money into public education and yet illuminate substantial geographic inequality in the ways these funds are distributed.

In just a few decades, school choice policies have shifted from the fringe of education policy discussions to a central focus of contemporary education reform. The rise in support for charter schools in particular has taken shape alongside a longstanding discourse that says our traditional public schools are in crisis and require a shift toward market-oriented practices ([
Philanthropic foundations have played a central role in this transformation. In the 2000s, major philanthropic foundations in the United States dramatically increased their funding flows to charter school organizations and other nontraditional education providers (e.g., Teach For America) while proportionately decreasing funding to traditional public schools and associated institutions ([
Recent evidence indicates that philanthropic foundations prefer to fund national-level advocacy and charter management organizations (CMOs) to advance charter school reform ([
The practice of convergent grant funding is central to understanding these efforts because the capability of foundations to influence education policy comes not from individual endowments but rather the combination of funding flows working through a network context ([
In this paper, we make use of a longitudinal data set to address the following questions:
Research Question 1: What types of organizations do philanthropic foundations fund to advance charter school reform, and how have these funding patterns changed over time?
Research Question 2: In which states have philanthropic foundations converged to support charter school reform?
Research Question 3: What are the market, policy, and organizational conditions associated with state-level processes of convergent grant funding?
To address these questions, we use statistical modeling techniques from social network analysis and basic principles of cartography to analyze funding data from 15 foundations in 2009, 2012, and 2014. We find that over this time period, foundations maintained a consistent distribution of funds across geographic scales (i.e., national vs. state/local) but increased the proportion of funds directed to CMOs and advocacy organizations in select clusters of states. A meaningful portion of the variation in this interstate convergent grant funding was associated with supply and demand for charter schools and select evidence of charter school effectiveness. However, the policy contexts of states and prior funding patterns were also associated with changes in the frequency with which the same foundations funded charter school organizations in the same clusters of states.
The findings from our analysis identify some of the conditions through which private foundations work to influence charter school reform at the state level. Although our observational design constrains causal conclusions, the results reveal substantial geographic inequality in how foundations fund charter school reform and provide insight into the potential ways public policy and research can shape how these funds are distributed in the future. These insights thus have direct implications for researchers, stakeholders, and policymakers given the extent to which charter school reform has become dependent on investment from private foundations.
Foundations seeking to support organizations that promote charter school policies must navigate multiple contexts that can both challenge or facilitate their efforts. On the surface, these decisions may reflect simple economic exchanges through which foundations choose to fund organizations that appear able to produce outcomes most closely aligned to their objectives. Our theoretical approach, however, assumes these exchanges are embedded in a variety of strategic action fields that shape these relationships ([
Foundations that practice strategic philanthropy in the realm of education policy operate in a networked environment ([
Aside from providing financial capital, foundations play an important role in these contexts by acting as knowledge brokers ([
Finally, foundations operate within and between political fields that facilitate or complicate the capacity for charter school policies ([
Numerous testable hypotheses can be derived from the theoretical perspective outlined previously. First, market theory expects that foundations will converge in state subsystems with a relatively low supply (e.g., minimal funding or support) and high demand for charter schools (e.g., low-achieving public schools). These flows should also converge in clusters of state subsystems where there is evidence that charter schools outperform traditional public schools. As identified in the aforementioned literature, evidence acquired from reports disseminated outside of academic journals should be more influential than evidence appearing in peer-reviewed journals. Third, we hypothesize that foundation convergence will more frequently occur in states with policy conditions favorable to charter school reform. This includes states without caps on charter school growth, automatic exemptions from collective bargaining agreements, and states that have been awarded RTTT grants. Finally, foundations should converge their funding flows in state subsystems where other foundations are headquartered and previous convergent funding relationships have been established. Given the uncertainty involved with funding in education policy, previous funding activity is likely to signal that other foundations are already working to build the capacity for charter school growth.
The sources of data for the analysis included foundation grants, state-level attributes, and journal articles and reports concerning state- and local-level charter school outcomes. First, we collected and entered information related to grants awarded by 15 foundations to charter school organizations in 2009, 2012, and 2014. We chose to use 2009 as our initial data point because we wanted to capture funding flows to charter school organizations immediately before and after the Obama administration’s RTTT initiative. The 2009 cutoff creates a potential source of bias toward more recent patterns of funding, but prior research suggests patterns of convergent funding have been accelerating since at least 2005 ([
Grant data were collected through a combination of foundations’ 990 tax documents, databases on foundation websites, and annual reports.1 [
We then collected attribute data for each state where charter schools were legal prior to 2009. These 39 states and the District of Columbia included those where local charter school organizations did not receive any grants from the foundations in the sample during the time period under analysis. For each state, we created dummy variables for a variety of attributes related to supply and demand, policy context, and organizational capacity. In particular, the variables indicated whether or not each state: (a) offered startup funds to charter schools, (b) was below basic proficiency on National Assessment of Eduational Progress (NAEP) assessments in either math or reading for Grades 4 and 8, (c) removed caps on charter school growth, (d) provided charters with automatic exemptions from collective bargaining agreements, (e) received RTTT funds, and (f) houses the organizational headquarters of one or more of the sampled foundations. Note that some variables were measured at different times depending on whether they were included in the 2012 or 2014 model (see additional details in the following).
For the evidentiary data, we searched the literature for studies released or published between 2009 and 2013 that attempted to measure the effectiveness of student achievement in charter schools at state and local levels. Thus, studies that measured the effects of charter schools at the national level and those that did not reveal the geographic location of the schools were excluded from our analysis. Each study was then coded based on the evidence of charter school effectiveness in terms of student achievement relative to traditional public schools: higher, lower, same, or mixed. We also coded whether the studies had appeared in peer-reviewed journals. In the end, a total of 25 studies with state-level data were included in our evidence sample (see [
Our analytic approach began with a descriptive look at the foundations’ giving patterns to charter school organizations between 2009 and 2014. We first examined changes over time in the types of charter school organizations receiving funding (e.g., CMOs, education managements organizations [EMOs], advocacy). Next, we explored the geographic context of these giving patterns by identifying the states where organizations received the most funding from the sample of foundations. To do this, we used choropleth maps of the United States and a two-mode matrix to illustrate the geographic distribution of the funding flows across all three years under analysis. For the state-level results, we focused on those grants awarded to organizations with clearly defined roles at the state or local level and excluded those grants to organizations whose work focuses on a national scale. For example, 50CAN is headquartered in Washington, D.C., but engages in advocacy efforts in numerous states. Thus, it cannot be assumed that an award to 50CAN is an award intended to impact charter reform in the District of Columbia.
The descriptive findings help set the stage for testing our model of interstate funding flows. One approach to testing this model would be to use individual states as the unit of analysis in which the dependent variable measures the number of foundations awarding grants to charter school organizations in each state. However, since our objective is to understand interstate convergence, we used a dyadic unit of analysis indicating the number of foundations that each pair of states shared in common. These state-by-state dyads provided a measure of the extent to which the same foundations funded charter school reform in the same sets of states (i.e., interstate convergent grant funding). This dyadic approach allowed us to directly identify the market, policy, and organizational conditions through which multiple states attract the same funders.
To prepare the data for our model, we first created foundation-by-state affiliation matrices for 2009, 2012, and 2014. Each affiliation matrix indicated whether or not foundation i had funded one or more charter school organizations in state j. Each matrix was then pre-multiplied into a state-by-state matrix in which the off-diagonal cells indicate the number of foundations that funded charter school organizations in both states j and k. For example, if California and New York shared six foundations in common in 2012, then we know that six of the foundations from our sample converged in those two states to fund charter school organizations during that year. The state-by-state dyads in the 2012 and 2014 matrices comprised the dependent variables in our analysis, and the 2009 matrix was used as a set of independent variable dyads measuring previous interstate convergent grant funding activity (analogous to prior test scores in a model of student achievement). Thus, as described in the following, we tested our model of interstate convergent funding on the 2012 and 2014 matrices.
For the independent variables in the analysis, we converted the state-by-attribute vectors into the same state-by-state matrices discussed previously, with the values indicating whether or not states j and k shared a given attribute in common. This means there were as many matrices as attribute vectors in the original file. In the 2009–2011 peer-reviewed journal evidence matrix, for example, a value of 1 in the California/New York cell indicated that peer-reviewed journal evidence of student achievement gains in charter schools were present for both states during those years. Just as the dependent variable is a matrix of interstate convergence dyads, the independent variables are also made up of matrices of interstate attribute dyads.
The primary analytical objective in the analysis was to model changes in interstate convergent grant funding as a function of the independent dyadic variables. However, standard ordinary least squares (OLS) regression was not appropriate since by definition we could not assume the interstate dyads were independent observations but instead interdependent conditional on the row or column location. [
The standard practice for testing hypotheses with dyadic units of analysis—which is common in social network analysis—is quadratic assignment procedure (QAP) regression. QAP regression allows researchers to model changes in dyadic dependent variables using dyadic independent variables while keeping Type 1 error rates at an acceptable level—even if autocorrelated errors are observed (see Figure 2 in [
We used QAP regression to test our model of interstate convergent grant funding on the 2012 and 2014 matrices.3 [

The model was tested in stepwise fashion beginning with the sources of evidence and supply/demand (B
We begin with a descriptive look at the overall patterns of grant funding from the major foundations in our sample to charter school organizations. Figure 1 illustrates the changes in the distribution of total funds across the different types of charter school organizations. It is immediately apparent that the organizational priorities of these foundations shifted over time away from charter school funds and individual schools toward advocacy organizations and CMOs. The latter organizations received 26.9% and 30.0% of the total funds given by these foundations to charter school reform organizations in 2014—up from 12.2% and 19.9%, respectively, in 2009. The National Association of Charter School Authorizers ($5 million), California Charter Schools Association ($4.7 million), and Black Alliance for Educational Options ($3.5 million) were the top funded advocacy organizations in 2014, while the top CMOs included Building Excellent Schools ($12.9 million), Success Academy ($6.3 million), and KIPP ($3.5 million). However, some CMOs have foundations and local operations. For example, in 2014, KIPP Foundation ($9.7 million) and KIPP’s local CMOs (e.g., KIPP NYC) also received grants that brought the total KIPP funding to $13.5 million during that year alone.
Distribution of funding across categories of charter school organizations for 2009, 2012, and 2014
While the total funding for advocacy organizations and CMOs grew to be greater than that of charter school funds and schools, individual organizations within the latter categories still received some of the largest amounts of funding overall and in 2014. For example, the Charter School Growth Fund received more grant funding than any other organization across all three years, with a three-year total of $45.6 million and $9.5 million in 2014 (third overall).4 [
The geographic distribution of the funds awarded was highly concentrated, with 80% of the total funding across all three years being awarded to organizations in only 10 of the 39 states and District of Columbia. The tendency to increase funding to advocacy organizations and CMOs over time (see Figure 1) was generally consistent among each of these states.5 [
Choropleth maps showing geographic distribution of (a) total and (b) per charter school student funding aggregated across 2009, 2012, and 2014
Figure 3 adds greater context to the geographic findings by illustrating the number of years each foundation granted funds to at least one charter school organization in a given state. The rows and columns are sorted to show the foundations that tended to fund organizations in the same states while also illustrating the states where organizations received funding from the same foundations. Next to Walton’s funding in 25 states (plus Washington, D.C.), what comes to the fore is the cluster of states—New York, California, and Louisiana—that shared a substantial portion of funders in common. There are a number of other states that shared two or three funders in common and many more that did not share any funders. Among the funders, Walton, Calder, and Gates were especially consistent in the geographic distribution of their support for charter school organizations. Broad, Dell, and Kellogg formed a second tier of foundations whose geographic activity in the charter sector was similar across these years. The remaining foundations focused primarily on one or two states in addition to the national-level organizations they may have funded (not shown in Figure 3).
Foundation by state matrix showing geographic funding activity among the sample of foundations across 2009, 2012, and 2014 Cell values range from 0 to 3 and indicate the number of sample years (2009, 2012, 2014) a foundation funded at least one organization in a given state.
It is clear from Figures 2 and 3 that foundations often shared geographic preferences in their support of charter school reform. But what draws foundations to fund organizations in the same set of states while excluding others? To gain insight into this question, we now turn to the QAP regression of interstate convergence. [

In Model 1, both of the evidentiary variables were significant, indicating that 2012 interstate convergence was positively associated with evidence of charter school effectiveness appearing in both peer-reviewed journals and non–peer reviewed journal sources. About a quarter (4 of 17) of these sources of evidence were funded by one or more of the foundations in the sample.6 [
Among the policy variables added in Model 2, only the receipt of RTTT funding accounted for any variation in 2012 interstate convergence. The RTTT coefficient was positive, suggesting that states receiving these funds also attracted higher levels of interstate convergent grant funding than those states that did not receive RTTT awards. The positive coefficient observed in Model 2 decreased but remained significant in Model 3 after controlling for all covariates in the model. Since the removal of caps on charters was a key component of RTTT, controlling for the absence of caps means the positive association of RTTT funds serves as a proxy for broader support of major reforms. The coefficients for absence of caps on charters and automatic exemptions from collective bargaining agreements were negative but not significantly different from zero across Models 2 and 3.
Previous interstate convergence and the co-presence of an in-state foundation were both significant, as expected. In other words, the more foundations a pair of states shared in common in 2009, the more they tended to share, on average, in 2012 when controlling for all variables in the model. Once the 2009 interstate convergence and in-state foundation variables were included, the full model accounted for 58% of the variation in 2012 interstate convergence. This is nearly double the proportion of variation explained in Model 2 (0.30) and nearly triple that of Model 1 (0.20). Overall, previous interstate convergence (0.557) and co-presence of an in-state foundation (0.176) were the largest standardized coefficients in the full model, followed by RTTT funding (0.170) and non–peer reviewed journal evidence (0.150).
The results for the 2014 model of interstate convergence were similar to those in 2012 (see [

State dyads receiving RTTT funds from the later round of awards (2012–2013) were also positively associated with interstate convergence in 2014 across all models. The coefficient for the absence of charter caps was again negative, yet in the 2014 model, it was significant in Model 2 and appears to have been mediated through prior convergence. This suggests that in 2014, foundations in our sample converged in states less frequently when those states did not have caps on charter schools. Finally, while still significant, the in-state foundation variable was negative in the 2014 model despite a positive bivariate correlation with the dependent variable (0.149, p < .05). When controlling for prior convergence in 2012, the co-presence of an in-state foundation was then associated with a decrease in interstate convergence in 2014. Once again, next to previous interstate convergence (0.726) and co-presence of an in-state foundation (–0.095), the co-presence of non–peer reviewed journal evidence (0.129) and RTTT funds (0.089) had the largest absolute standardized coefficients.
Our primary objectives in this paper were to describe and model the interstate convergence of foundation grants to charter school organizations in the United States between 2009 and 2014. At the outset, we argued that a focus on interstate convergent grant funding was needed to better understand the strategies foundations pursue to influence charter school reform. This argument rests on the notion that the power of foundations is greatest when leveraged through affiliations with other funders rather than as individual organizations. Thus, our focus on modeling variation in the number of foundations that states shared in common allowed us to gain insights into why some foundations are concentrating on building organizational capacity in certain clusters of states and not others.
Our theoretical perspective assumed that the frequency with which states shared foundations in common covaried with multiple state-level attributes related to supply and demand, evidence, policy, and prior funding affiliations. Overall, we found some evidence supporting each dimension of our theoretical model. First, we found support for our hypothesis that foundations converged in states where evidence from studies—some of which were funded by the foundations in our sample—suggested charter schools were associated with positive student achievement outcomes. Although evidence from peer-reviewed journals appeared to have been mediated through prior funding activity, evidence appearing outside of academic journals was consistently significant (and of larger magnitude) when controlling for all variables in the 2012 and 2014 models. This finding was anticipated by previous research that has explored the use of research in education policy ([
We also saw that features of the policy climate in states were associated with changes in the frequency of interstate convergent funding patterns. Most notably, states that received RTTT grants during both time periods under analysis shared more foundations in common when controlling for all other covariates in the models. Thus, foundations tended to converge in states that had been awarded federal funds to, among other things, expand school choice options. These federal investments in states working to bolster jurisdictional challengers further leveraged the power of foundations interested in promoting charter school reform ([
Finally, prior affiliations in states were evidently a driving force in interstate convergent funding of charter school organizations. In both models, these affiliations explained a substantial portion of the variation in the patterns of interstate convergence. This suggests that foundations working to build the organizational capacity of charter schools look across multiple states to existing investments and infrastructure established by other foundations ([
The findings that emerged from our analysis provide important insights for policymakers and researchers paying attention to the ways that private wealth is shaping public education in the United States. Foundations have historically played an influential role in constructing and transforming the education system, but a new wave of philanthropists are implementing strategies previously unseen in the education sector ([
