Mapping Exclusion, Missing Intersections

Literature Review · 2026 Qiyun Wang

Brief Summary

Racial disparities in school discipline remain a defining challenge in U.S. education, with Black students disproportionately subjected to exclusionary practices that contribute to the school-to-prison pipeline (Losen & Gillespie, 2012). In Science Advances, Candipan and Hailey (2026) link census and Civil Rights Data Collection (CRDC) data via school zone shapefiles. They reveal a notable spatial divergence: from 2010-2018, suspension disparities declined in urban centers but intensified in demographically shifting suburban and rural neighborhoods. This valuable spatial dimension demonstrates how neighborhood-level racial change drives exclusionary outcomes relative to static demographics.

Where the study productively applies Racialized Organizations Theory (Ray, 2019), it simultaneously operates within a "single axis" framework (Crenshaw, 1989) isolating race from ability, overlooking how disability labels function as bureaucratic gateways to exclusion. By failing to employ intersectionality as a transformative framework (García & Ortiz, 2013), the authors miss the full architecture of exclusionary systems. Applying the lenses of QuantCrit (Garcia et al., 2018) and DisCrit (Annamma et al., 2013), this review argues that addressing contemporary discipline disparities requires dissecting the structural interplay of race, disability, and institutional power, moving past merely documenting isolated outcomes.

Background and Theory

Anchoring their analysis in Racialized Organizations Theory (Ray, 2019) and the Racial Threat hypothesis (Blalock, 1967; Blumer, 1958), Candipan and Hailey effectively explain how demographic shifts precipitate institutional defensiveness, demonstrating strong command of the empirical landscape (e.g., Welch & Payne, 2010; Welsh, 2023). Yet the study remains theoretically constrained. Paradoxically, despite citing Crenshaw et al. (2015) on policing, the authors bypass Crenshaw's foundational warning (1989) against the very single-axis analysis they employ. Epistemologically rooted in the white imaginary, the Racial Threat framework centers dominant groups' threat perceptions over Black students' lived experiences. This precipitates the study's most significant omission: the disability dimension.

Even as highlighting behavioral criminalization, the authors overlook its medicalization. They discuss teacher perceptions but fail to interrogate the institutional link between behavioral labels and special education. As Ford (2012) and Skiba et al. (2002) document, culturally distinct Black behaviors are systematically misread as Emotional and Behavioral Disorders (EBD). Framing educator discretion as a binary choice between restorative and exclusionary measures omits a consequential third option: referral for special education (García & Ortiz, 2013). By overlooking this critical gateway, the study fails to engage with DisCrit (Annamma et al., 2013). Excluding this intersectional lens implicitly adopts a medical model that locates deficits within the student, accepting a binary of "normal" versus "disruptive" without interrogating whose cultural standards are operationalized as order (Leonardo & Broderick, 2011).

Research Methods

Methodologically, linking longitudinal CRDC data (2010-2018) with census tracts offers strong national generalizability, whereas the fixed effects (FE) approach appropriately controls for stable school-level confounders. However, this design imposes a significant epistemological distance from Black students' lived realities. Utilizing suspension rates as the sole proxy for exclusionary discipline reproduces "white logic" (Zuberi & Bonilla-Silva, 2008), treating administrative counts as objective truths. Conceding these data are a "conservative estimate", which counts students suspended at least once rather than total incidents, systematically invisibilizes the cumulative disciplinary encounters experienced by Black students with disabilities, who face the highest rates of repeat removal (Annamma et al., 2013).

Furthermore, even if CRDC disability data are historically fraught with underreporting, this 'messiness' is a feature of the system, not a bug to be deleted. Excluding this dimension due to data quality concerns essentially allows the limitations of administrative surveillance to dictate the boundaries of sociological inquiry, thereby legitimizing the invisibility of Black students with disabilities. Although they cited intersectional scholars like Morris (2015) and Crenshaw et al. (2015) to justify sample selection, this engagement appears perfunctory as it is not operationalized in the statistical model.

The reliance on Fixed Effects (FE) regression warrants further critical interrogation regarding standard linear model assumptions. Granting that FE models control for time-invariant school characteristics, they cannot account for time-varying omitted variables. DisCrit scholarship suggests that disability labeling is dynamic and often covaries with racial demographics; as neighborhood Black populations increase, schools may defensively increase the use of subjective labels like EBD. Therefore, by omitting disability status, the model remains susceptible to time-varying omitted variable bias, potentially misattributing variance associated with special education classification to neighborhood racial change.

Furthermore, the statistical interpretation relies on Null Hypothesis Significance Testing (NHST) in ways that require caution. Following Greenland et al. (2016), characterizing disparities in racially stable neighborhoods as "unchanged" based solely on p values exceeding 0.10 is problematic. The absence of statistical significance does not imply the absence of an effect; rather, it indicates data compatibility with the null hypothesis. By framing nonsignificant results as stability, the analysis risks normalizing chronically high baseline levels of exclusion.

Additionally, to stabilize this measure, the authors top-code extreme suspension rate ratios at 20, which effectively flattens the regression slope, introducing a downward bias that underestimates the true magnitude of racial threat. From a QuantCrit perspective (Gillborn et al., 2018), these outliers are not statistical noise but represent the precise institutional sites of hyper-segregation most in need of scrutiny. Finally, the absence of a positionality statement reflects what Haraway (1988) critiques as the "god trick" of disembodied objectivity, obscuring how the researchers' own identities may influence their interpretation of deficit-based narratives.

Results and Conclusions

The study makes a meaningful empirical contribution by documenting the spatial and temporal divergence in school discipline disparities: urban gaps narrowed, in stark contrast to the widening gaps observed in suburban and rural communities experiencing racial demographic change. This finding alone advances the literature beyond static, cross-sectional portraits of discipline disproportionality. Nevertheless, a Critical Race analysis utilizing Bell's (1980) interest convergence principle reveals a profound irony in the broader trends: the overall, nationwide decline in exclusionary discipline was driven disproportionately by the insulation of white students (a 29% decline) rather than a fundamental restructuring for Black students (only a 16% decline). This suggests equity-focused reforms may inadvertently reproduce stratification by yielding greater relative benefits for dominant groups, leaving the structural drivers of anti-Blackness intact even as absolute suspension rates decrease.

In rural contexts, findings challenge Racial Threat Theory: Black suspension likelihood increased markedly even where Black populations decreased. Rejecting the authors' "institutional lag" explanation, a Critical Human Geography perspective reframes this as "exclusionary displacement" (Marcuse, 1985). In resource-scarce settings, high-intensity discipline reinforces community homogeneity, a process depoliticized when reduced to mere administrative capacity. This depoliticization extends to recommendations advocating the transplantation of urban interventions to rural contexts. Such technical amelioration addresses administrative consequences but ignores the structural source: a persistent investment in spatial exclusivity (Lipsitz, 2006). Without dismantling the underlying threat perception, these reforms risk becoming symbolic exercises leaving the architecture of exclusion intact.

Ultimately, the study's most consequential gap is internal underspecification rather than external misappropriation. By correlating neighborhood Black population change with intensified discipline without sufficiently theorizing causal mechanisms, the narrative risks implying that demographic integration itself generates friction. Situating this association explicitly within institutional rigidity (Ray, 2019) to clarify that escalation reflects organizational response rather than demographic presence is analytically necessary, particularly as SFFA v. Harvard (2023) and the Dismantle DEI Act (S. 4516, 2024) create a climate where underspecified frameworks risk essentialist assimilation. Beyond these limitations, future research merging DisCrit with geographic methods is essential to dismantle the full exclusionary architecture of American schools.
