Absenteeism.org is an independent informational resource focused on school attendance and chronic absenteeism in the United States. The site brings together attendance data, state requirements, district information, practical calculators, definitions, and explanatory guides in one place.
The goal is to make school attendance information easier to understand and compare without requiring families, educators, researchers, and other readers to search through multiple government databases, district documents, policy manuals, and reports.
What Absenteeism.org Covers
Absenteeism.org focuses primarily on U.S. K–12 school attendance. Topics include chronic absenteeism, truancy, excused and unexcused absences, compulsory school attendance, attendance rates, state laws, district policies, student absence patterns, and the academic effects associated with missing school.
The site also provides tools that help users work with common attendance figures, such as missed school days, attendance percentages, chronic absenteeism thresholds, and attendance targets.
State Attendance Information
School attendance requirements are not identical across the United States. Compulsory attendance ages, truancy rules, absence definitions, intervention procedures, documentation requirements, and enforcement practices can differ by state and may also vary locally.
State-focused coverage is intended to bring together the most relevant attendance information for each jurisdiction, including available chronic absenteeism data and the rules that affect how school absence is defined and handled.
District Information
Attendance policies are often implemented at the school district level. Districts may publish their own attendance procedures, absence reporting requirements, intervention practices, calendars, and student handbooks while operating within state law.
District coverage may include chronic absenteeism statistics, attendance trends, policy information, enrollment context, and other publicly available data that helps readers understand local attendance conditions.
Chronic Absenteeism Data
Chronic absenteeism is commonly used to describe students who miss a significant share of the school days in which they are enrolled. A threshold of 10 percent of enrolled school days is widely used in U.S. education reporting, although definitions and reporting practices can vary between jurisdictions and datasets.
Absenteeism.org distinguishes the school year represented by a dataset from the date on which the information was published or reviewed. This is important because education statistics are frequently released months after the school year they describe.
Data from different states or districts may not always be directly comparable. Differences can result from reporting methods, student populations, absence definitions, suppression rules, school calendars, data revisions, or changes in methodology.
Attendance Laws and Truancy
Chronic absenteeism and truancy are related but separate concepts. Chronic absenteeism generally measures the amount of school a student misses, while truancy is typically connected to unexcused absences and legal or administrative attendance requirements.
Because truancy laws and compulsory attendance requirements are established primarily at the state level, legal thresholds and terminology can vary considerably. Local school districts may also establish procedures for notices, interventions, documentation, and attendance review.
Information about attendance laws on Absenteeism.org is provided for general educational purposes. Official statutes, regulations, state education agencies, school districts, and schools remain the appropriate authorities for individual cases.
Calculators and Practical Tools
Absenteeism.org provides attendance calculators designed to make common attendance calculations easier to understand. Depending on the tool, users may be able to estimate attendance percentages, determine how missed days compare with a chronic absenteeism threshold, or calculate the attendance needed to reach a particular target.
Calculator results are estimates based on the values entered by the user. They do not replace official attendance records and do not determine a student’s legal, disciplinary, academic, or enrollment status.
Sources and Research Approach
Preference is given to authoritative and publicly available sources, including state education agencies, federal education agencies, state statutes and regulations, school districts, official data portals, government reports, and established education research organizations.
Source dates and school years are considered separately where possible so that older statistics are not presented as though they describe a newer school year.
When different sources use different definitions or reporting methods, those differences may be reflected in the way information is presented rather than combining incompatible figures into a single comparison.
Updates and Corrections
School attendance information changes over time. States may amend attendance laws, districts may revise policies, agencies may publish new datasets, and previously released statistics may be corrected or replaced.
Pages may therefore be updated as newer or more authoritative information becomes available.
Readers who identify a possible error, outdated figure, broken source, or material change in an attendance rule may report it by email. Useful correction requests should identify the affected state, district, school year, statistic, or policy and, where possible, include the relevant public source.
Independence
Absenteeism.org is an independent website. It is not operated by the U.S. Department of Education, a state education department, a school district, a school, or another government agency.
References to government agencies, districts, schools, organizations, research projects, or datasets do not imply sponsorship, endorsement, or affiliation unless specifically stated.
Who the Site Is For
Absenteeism.org is designed for parents, families, students, educators, school staff, researchers, journalists, policymakers, and anyone seeking clearer information about school attendance in the United States.
The site is intended to help readers understand attendance data and general rules more quickly while making it clear when an official school, district, agency, or legal source should be consulted for a specific situation.
