Education reform is the goal of changing public education. The meaning and educational methods have changed through debates over what content or experiences result in an educated individual or an educated society. Historically, the motivations for reform have not reflected the current needs of society. A consistent theme of reform includes the idea that large systematic changes to educational standards will produce social returns in citizens' health, wealth, and well-being.

As part of the broader social and political processes, the term education reform refers to the chronology of significant, systematic revisions made to amend the educational legislation, standards, methodology, and policy affecting a nation's public school system to reflect the needs and values of contemporary society. In the 18th century, classical education instruction from an in-home personal tutor, hired at the family's expense, was primarily a privilege for children from wealthy families. Innovations such as encyclopedias, public libraries, and grammar schools all aimed to relieve some of the financial burden associated with the expenses of the classical education model. Motivations during the Victorian era emphasized the importance of self-improvement. Victorian education focused on teaching commercially valuable topics, such as modern languages and mathematics, rather than classical liberal arts subjects, such as Latin, art, and history.

Motivations for education reformists like Horace Mann and his proponents focused on making schooling more accessible and developing a robust state-supported common school system. John Dewey, an early 20th-century reformer, focused on improving society by advocating for a scientific, pragmatic, or democratic principle-based curriculum. Whereas Maria Montessori incorporated humanistic motivations to "meet the needs of the child". In historic Prussia, a motivation to foster national unity led to formal education concentrated on teaching national language literacy to young children, resulting in Kindergarten.

The history of educational pedagogy in the United States has ranged from teaching literacy and proficiency of religious doctrine to establishing cultural literacy, assimilating immigrants into a democratic society, producing a skilled labor force for the industrialized workplace, preparing students for careers, and competing in a global marketplace. Educational inequality is also a motivation for education reform, seeking to address problems of a community.

Education reform, in general, implies a continual effort to modify and improve the institution of education. Over time, as the needs and values of society change, attitudes towards public education also change. As a social institution, education plays an integral role in the process of socialization. "Socialization is broadly composed of distinct inter- and intra-generational processes. Both involve the harmonization of an individual's attitudes and behaviors with that of their socio-cultural milieu." Educational matrices aim to reinforce those socially acceptable informal and formal norms, values, and beliefs that individuals need to learn in order to be accepted as good, functioning, and productive members of their society. Education reform is the process of constantly renegotiating and restructuring the educational standards to reflect the ever-evolving contemporary ideals of social, economic, and political culture. Reforms can be based on bringing education into alignment with a society's core values. Reforms that attempt to change a society's core values can connect alternative education initiatives with a network of other alternative institutions.

Education reform has been pursued for a variety of specific reasons, but generally most reforms aim at redressing some societal ills, such as poverty-, gender-, or class-based inequities, or perceived ineffectiveness. Current education trends in the United States represent multiple achievement gaps across ethnicities, income levels, and geographies. As McKinsey and Company reported in a 2009 analysis, "These educational gaps impose on the United States the economic equivalent of a permanent national recession." Reforms are usually proposed by thinkers who aim to redress societal ills or institute societal changes, most often through a change in the education of the members of a class of people—the preparation of a ruling class to rule or a working class to work, the social hygiene of a lower or immigrant class, the preparation of citizens in a democracy or republic, etc. The idea that all children should be provided with a high level of education is a relatively recent idea, and has arisen largely in the context of Western democracy in the 20th century.

The "beliefs" of school districts are optimistic that quite literally "all students will succeed", which in the context of high school graduation examination in the United States, all students in all groups, regardless of heritage or income will pass tests typically fall beyond the ability of all but the top 20 to 30 percent of students. The claims clearly renounce historical research that shows that all ethnic and income groups score differently on all standardized tests and standards based assessments and that students will achieve on a bell curve. Instead, education officials across the world believe that by setting clear, achievable, higher standards, aligning the curriculum, and assessing outcomes, learning can be increased for all students, and more students can succeed than the 50 percent who are defined to be above or below grade level by norm referenced standards.

States have tried to use state schools to increase state power, especially to make better soldiers and workers, and increase nationalism. This strategy was first adopted to unify related linguistic groups in Europe, including France, Germany and Italy. Exact mechanisms are unclear, but it often fails in areas where populations are culturally segregated, as when the U.S. Indian school service failed to suppress Lakota and Navaho, or when a culture has widely respected autonomous cultural institutions, as when the Spanish failed to suppress Catalan.^{[citation needed]}
