Absenteeism.org is an independent informational resource focused on school attendance, chronic absenteeism, truancy, attendance laws, district information, attendance data, and related educational topics in the United States.
Informational purposes only
The information published on Absenteeism.org is provided for general informational and educational purposes. It should not be treated as legal advice, professional educational advice, medical advice, or an official determination concerning any student’s attendance status.
Attendance laws and policies vary
School attendance requirements may differ significantly by state, school district, school, grade level, program, student circumstances, and school year.
Terms such as chronic absenteeism, truancy, habitual truancy, excused absence, unexcused absence, attendance rate, compulsory attendance, and excessive absence may have different legal or administrative definitions depending on the jurisdiction.
Users should consult the applicable school, district, state education agency, statute, regulation, or other official authority when making decisions that depend on current attendance requirements.
Data limitations
Attendance statistics may be reported on different schedules and may cover different school years. Some jurisdictions revise previously reported data, suppress small student groups, change definitions, or calculate measures differently.
For these reasons, figures from different states, districts, school years, or data systems may not always be directly comparable.
Where a publication year and a data year differ, the data year is generally the relevant period for interpreting the statistic.
Calculator results
Calculators available on Absenteeism.org provide estimates based on user-entered values and mathematical assumptions. Results are intended to help users understand attendance percentages and possible scenarios.
A result generated by a calculator is not an official school record and does not establish whether a student is legally truant, chronically absent under a particular reporting system, eligible for course credit, subject to an intervention, or compliant with a local attendance policy.
Official sources control
If information on Absenteeism.org differs from an applicable statute, regulation, government publication, state education agency guidance, school district policy, or official student record, the applicable official source should be relied upon.
Independent website
Absenteeism.org is not a federal or state government agency, school district, school, or official education department. References to agencies, schools, districts, organizations, datasets, or government programs do not imply endorsement or affiliation.
No guarantee
Although reasonable efforts may be made to keep information accurate and useful, Absenteeism.org does not guarantee that all information will always be complete, current, applicable, or free from error.
Users are responsible for verifying information before relying on it for legal, academic, disciplinary, enrollment, financial, or other important decisions.
