Education Policy Tools Are Never Neutral: Review Maps How Tests and Indicators Reshape Power

When a ministry of education introduces a new standardized test, a school-evaluation framework, a performance indicator, or an accreditation procedure, the change often looks purely technical—a matter of measurement, logistics, and compliance. A new scoping review argues that this appearance is misleading. Policy instruments, the review contends, are never neutral: they define what counts as a policy problem, establish which kinds of knowledge are credible, allocate roles to different actors, and shape how schools and entire education systems are governed. Far from simply implementing decisions that have already been made, the tools of education policy actively make policy as they operate.

The review, published online on August 1, 2026, in ECNU Review of Education, was conducted by Luís Miguel Carvalho and Catarina Gonçalves of the Institute of Education, University of Lisbon. The authors examined 42 peer-reviewed articles published between 2005 and 2023, mapping a body of work known as the sociology of policy instruments in education. Their goal was twofold: to take stock of what this research tradition has revealed about contemporary education policy, and to identify where the field should go next. The result is both a synthesis of nearly two decades of scholarship and a framework for understanding how apparently mundane administrative devices carry profound political weight.

The intellectual core of the sociology of policy instruments is the claim that instruments are simultaneously technical and social devices. Legislation, contracts, assessments, benchmarks, indicators, funding mechanisms, and communication platforms all embody specific values and assumptions about the relationship between government, education professionals, learners, and society. A national testing regime, for instance, encodes beliefs about what knowledge matters, how learning should be demonstrated, and who is entitled to judge school quality. A funding contract encodes assumptions about incentives and accountability. Studying these embedded assumptions, the review argues, makes it possible to see how power operates through arrangements that are usually presented as merely practical.

The literature reviewed shows a clear center of gravity. Researchers have concentrated especially on performance-based instruments: the OECD’s PISA assessments, national large-scale assessments, school evaluation and self-evaluation schemes, indicators, standards, and accreditation procedures. This concentration, the authors suggest, reflects a broader transformation in how education systems are governed—a shift toward governance through comparison, data, and performance-oriented accountability. In such systems, the instrument is not an afterthought to policy; it is the medium through which policy is imagined, debated, and enforced.

The review also documents a second trend in the research: growing attention to European education governance, to global intergovernmental organizations, to private companies, and to intermediary actors who work between national policy and local practice. This shift mirrors changes in the policy landscape itself. As international assessments and transnational benchmarks gain influence, the actors who design, interpret, and circulate these tools—organizations, consultants, data providers, and broker institutions—acquire authority that traditional accounts of education policy rarely captured. Instrument-based research, the review shows, is particularly well suited to illuminating this redistribution of influence.

To organize the existing knowledge, Carvalho and Gonçalves distinguish three dimensions. The first concerns the institutional ideas embedded in instruments—the values, theories of schooling, and assumptions about governance that tools carry within them. The second concerns the trajectories instruments follow as they are designed, adopted, and used in practice. The third concerns the effects instruments generate once they are in circulation. Crucially, the review emphasizes, instruments do not simply travel unchanged from policymaking centers to schools. National traditions, political interests, professional identities, and local conditions can lead to adoption, opposition, hybridization, or the creation of entirely new tools. A similar assessment or indicator scheme may therefore take quite different forms in different systems, depending on the institutional soil in which it is planted.

From this synthesis, the authors distill six recurring effects of policy instruments. Instruments can legitimize certain actors and coalitions while marginalizing others. They can reorganize political spaces and timelines, changing who participates in decision-making and on what schedule. They can privilege certain forms of knowledge and expertise over others, elevating statistical and managerial competence in the process. They can gather actors around common issues, creating new arenas of cooperation and contestation. They can produce hybrid policies when several tools and governing logics interact within the same system. And they can generate unintended consequences that no designer anticipated.

The review offers concrete illustrations of these dynamics. Comparative assessments such as PISA may strengthen the authority of international organizations and structure national debate around rankings and league tables. Indicators designed to inform policy deliberation can harden into simplified rankings that obscure the complexity they were meant to capture. Performance tools introduced to encourage innovation may instead intensify supervision or standardize classroom practice. In each case, the effect flows not from malice or error but from the way the instrument itself organizes attention, incentives, and authority—a reminder that design choices are consequential even when they appear innocuous.

“Studies on policy instruments are well suited to address the complexity of education policy: the multiple policy scales as interdependent contexts, the variety of individual and collective actors involved, and the various governance patterns, ranging from state-oriented to market-oriented regimes, and from norm-based governance patterns to performance-oriented ones,” said Carvalho and Gonçalves. The methodological strength of this approach lies precisely in its capacity to connect levels: a single testing regime can be analyzed simultaneously as a national political project, a transnational data infrastructure, a professional constraint on teachers, and a market opportunity for private providers. Few other lenses in education research hold these scales together so naturally.

The review is candid about its limits and the gaps it exposes. The evidence base remains strongly centered on Europe, leaving large regions of the world underrepresented in the literature. Researchers have also paid less attention to combinations of multiple instruments, even though real education systems almost always deploy tools in bundles rather than in isolation. The authors call for a broader geo-cultural range of studies, clearer theoretical foundations, and more systematic explanations of why the same instrument follows different trajectories in different settings. Answering these calls, they suggest, would turn a promising research perspective into a genuinely comparative science of educational governance.

For policymakers and education leaders, the findings carry a practical caution: choosing a policy instrument is itself a political decision. A test, an indicator, a contract, or a digital platform may affect not only whether a policy achieves its stated goals, but also what goals appear legitimate in the first place, who gains authority over schools, and which realities remain visible or become obscured by the data collected. A ministry that selects a new evaluation framework is, in effect, redrawing the map of who may speak credibly about education. Recognizing this does not mean abandoning instruments—governance without tools is impossible—but it does mean treating their selection and design as matters requiring the same scrutiny as policy content itself.

For researchers, the review provides a map of a developing field and a framework for examining the complex links between technical devices, institutional change, and power in education. The sociology of policy instruments, as synthesized by Carvalho and Gonçalves, invites scholars to ask deceptively simple questions about the tools that surround schooling: What ideas do they carry? Whose interests do they serve? How do they travel, mutate, and combine? And what worlds do they make possible—or foreclose? As education systems worldwide continue to embrace data, comparison, and performance, those questions grow only more urgent, and the instruments themselves grow only more consequential.
