The potential and problems of large high schools--and the related question of optimal school size--have been debated over the last 40 years and are of growing interest today. Approximately 70% of American high school students attend schools enrolling 1,000 or more students; nearly 50% of high school students attend schools enrolling more than 1,500 students. Some students attend schools enrolling as many as 4,000-5,000 students.

At the heart of the debate are three questions:

  • Are large or smaller schools are more effective in increasing student achievement and producing other important school outcomes?

  • How much of the benefits of smaller schools is related to size versus other factors such as smaller communities, supportive educational environments, instructional quality or parental involvement?

  • Can any benefits to smaller schools be produced by restructuring larger schools into smaller learning environments?

Although the research to date is largely non-experimental and hence must be interpreted with some caution, there is a large body of other evidence to suggest that smaller schools may have advantages over large schools. And while less is known about smaller learning environments within large high schools (so-called "schools-within-schools"), they presumably simulate the effects of small schools while retaining some of the advantages of large schools.

Among current research findings:

  • Large high schools, particularly those serving low-income students, have disproportionately lower achievement and higher incidences of violence than smaller schools serving similar student populations.

  • In small schools, students tend to be more satisfied, more academically productive, more likely to participate in school activities, better behaved, and less likely to drop out than students in large schools.

  • The size of high schools may have an indirect effect on student learning. Essentially, more moderately sized schools-those with 900 or fewer students-likely improve the climate and conditions for student success, especially teacher sense of self-efficacy and appropriate sense of responsibility for student learning, when accompanied by high expectations, standards and supporting strategies.

  • Smaller schools also may be safer because students feel less alienated, more nurtured and more connected to caring adults, and teachers feel that they have more opportunity to get to know and support their students.

  • While small schools have a higher cost per pupil than large schools, they have a lower cost per graduate[downloadable files] PDF (290K) since they tend to have lower dropout rates. Also, the higher percentage of dropouts from large schools carries additional societal costs.

  • At the same time, some high schools may theoretically be too small to provide adequate resources, and the effects of school size may be more important for some groups of students than others. (Reports available for a fee.)

Given these and other research findings, the Department of Education has taken steps to address the issue of high school size by offering schools resources to simulate the effects of small high schools within large high school campuses, which the majority of American students attend. Among federal efforts:

  • The No Child Left Behind Act of 2001 provides funds for the Smaller Learning Communities Program which helps local education agencies plan, implement, or expand small learning communities in large high schools. Through this program, the Department is also conducting new research to determine whether the effects of small schools can be replicated within large high schools; the ideal size of such communities; and the impact of breaking down large high schools on important outcomes such as achievement and equity.

  • No Child Left Behind also authorizes the Comprehensive School Reform Program which provides funding for states to implement several high school reform models, many of which are organized around smaller learning communities.

  • No Child Left Behind also provides funds for the Safe and Drug-Free Schools program to prevent violence in and around schools, and foster a safe and drug-free learning environment that supports student academic achievement.

Research and Evaluation

The authors discuss how and under what circumstances smaller classes make a difference, whether benefits outweigh costs, and the types of policy tradeoffs made to reduce class size.

  • The Cost Effectiveness of Small Schools [downloadable files]PDF (290K). Report that outlines research showing the desirable educational and community outcomes of small schools, and analyzes their cost-effectiveness. Extensive list of references included.

  • From Large to Small: Strategies for Personalizing the High School. Profiles examples of effective small schools, and synthesizes the key lessons about why they are effective. Also looks at the experiences of large high schools that broke into smaller learning communities but only reproduced inequities and ineffective practices, and discusses why those efforts foundered.

  • The Future of School Facilities: Getting Ahead of the Curve (Center on Reinventing Public Education, 2002). Paper on how five trends will change the way schools look and operate, leading to a more flexible approach where school facilities may be shared among K-12, college, community and business sites.

  • Improving Student Achievement: What State NAEP Test Scores Tell Us. RAND researchers compared NAEP results in 44 states to determine if there were measurable differences in student achievement among states, and if these differences could be tied to specific reform policies. They found that reforms aimed at reducing class size, increasing access to pre-school, reducing teacher turnover, and providing adequate resources for teachers at the classroom level seemed to be the most effective.

  • Monitoring School Quality: An Indicators Report
    [downloadable files] PDF(965K). Explores why some schools may be better than others at helping students learn. The report reviews 13 characteristics of schools, classrooms, and teachers that are most likely related to school quality and student learning. For each indicator, the report identifies where national data are currently available and reliable.

  • Report on American Education, 2001. Examines the achievement levels of American students to determine: (1) if there have been any significant changes over the last several decades; (2) if the American public is getting accurate information about student achievement; (3) how students are faring with regard to mathematics, in particular; and (4) how particular policies affect achievement.
