Chronic Absenteeism in CT: The 10% Rule, Truancy, and School Duties

Chronic absenteeism in Connecticut is defined by statute as missing ten percent or more of the days a student has been enrolled in a school year, counting every absence — excused, unexcused, and disciplinary alike. For a full 180-day year, that works out to 18 missed days. Crossing that threshold triggers school-based interventions under Connecticut law, but it does not, by itself, send anyone to court.

How the 10% Rule Actually Counts

The chronic absenteeism calculation is deliberately broad. It includes parent-excused absences, doctor-verified illness, religious observances, out-of-school suspensions, and everything else. If a day was missed, it counts.¹

A student is considered “in attendance” only if present at school or an approved school activity for at least half the regular school day. Fall short of that half-day mark and the whole day is logged as an absence. This matters more than families often realize. A child who regularly comes in after lunch or leaves early for appointments can rack up chronic-absenteeism days quickly, even when nobody considers them absent in the usual sense.

The ten-percent figure is also rolling against days enrolled, not against the full school year. A student who transfers mid-year is measured against the days enrolled in the new district, so the threshold can be reached faster than parents expect.

Chronic Absenteeism vs. Truancy

These are two different legal categories, and a student can fall into one without the other.

Truancy counts only unexcused absences. A student becomes a “truant” at four unexcused absences in any 30-consecutive-calendar-day period, or ten unexcused absences in a school year.²

Chronic absenteeism counts everything. So a child with 20 doctor-excused medical absences is chronically absent but not truant. A child with exactly ten unexcused absences is truant but may not be chronically absent if those are their only missed days. The two classifications set off different intervention pathways, and a student can be flagged under both at once.

Excused and Unexcused: The Rules Change at the Tenth Absence

Connecticut’s State Board of Education defines what counts as excused, unexcused, and disciplinary. The rules shift sharply once a student passes nine total absences in a year.³

For the first nine absences of the school year, a parent note is enough. If the parent or guardian provides written documentation within ten school days of the student’s return, the absence is excused.⁴

Starting with the tenth absence, only these reasons qualify as excused:

Illness verified by a licensed medical professional
A recognized religious holiday
A death in the student’s immediate family
A mandated court appearance
An educational opportunity pre-approved by a district administrator

Family vacations, oversleeping, and unverified illness are unexcused once the tenth absence is reached. A pattern of parent-note absences in September and October can leave a family unable to excuse a January illness without a doctor’s note.

What the School Must Do

Every local and regional board of education is required to adopt written truancy policies, and the law prescribes specific steps once a student is flagged.

Within ten school days of a student’s fourth unexcused absence in a month or tenth unexcused absence in the year, the school must hold a meeting with the parent or guardian and appropriate school staff to discuss the reasons behind the absences.²

Schools also carry ongoing attendance duties:

For students in kindergarten through eighth grade, the school must make a reasonable effort to notify a parent by phone and mail whenever the child is absent and the school has no indication the parent knows.
Schools must coordinate with and refer families to community agencies providing child and family services.
Schools with disproportionately high truancy rates, as determined by the Commissioner of Education, must implement a truancy intervention model that accounts for mental and behavioral health needs.

Boards must also notify parents of kindergarten through eighth-grade students, at the start of each year and upon any new enrollment, of their attendance obligations.²

Attendance Review Teams

Districts with a chronic absenteeism rate of ten percent or higher must create a District Attendance Review Team (DART). Individual schools with rates of fifteen percent or higher must have a School Attendance Review Team (SART). A district that meets both thresholds must stand up teams at both levels.¹

These teams can include administrators, guidance counselors, social workers, teachers, and community program representatives. They review individual cases, discuss what the school has tried, identify community referrals, and recommend next steps. Each team must meet at least once a month. Because Connecticut’s statewide chronic absenteeism rate sat around seventeen percent in 2024–2025, most districts are required to maintain at least a DART.⁵

Referral to a Youth Service Bureau

When school-level interventions aren’t working, the next escalation is a referral to a Youth Service Bureau (YSB), which coordinates community-based prevention and follow-up services for youth and families.⁶

A school cannot skip straight to a YSB referral. The following must be true first:

The mandatory parent meeting has already been held within ten days of the triggering absence.
The school has documented its efforts to contact and engage the family and to provide early intervention.
Other attempts to improve attendance have been exhausted. If the family is cooperating and interventions are showing results, a referral isn’t appropriate.

The referral must be signed by both the parent or guardian and an authorized school official. If the required documentation is missing, the YSB can send the referral back without acting on it.

Truancy No Longer Goes to Juvenile Court

Connecticut’s enforcement model changed in 2017, and the shift is worth knowing because older resources still describe the prior system. Before August 15, 2017, if a parent refused to cooperate with the school, the superintendent was required to file a complaint with Superior Court alleging a “Family with Service Needs” (FWSN), which brought the family before Juvenile Matters.

Public Act 16-147 eliminated that pathway. The law removed truancy from the FWSN definition and repealed the statutory requirement that superintendents file court complaints when parents didn’t cooperate.⁷ The Court Support Services Division of the judicial branch no longer accepts FWSN referrals based on truancy. The current FWSN definition still covers children who have run away, are beyond parental control, or have engaged in certain other conduct, but the statute limits FWSN petitions to those lawfully filed on or before June 30, 2020.⁸ Truancy is now handled entirely through school-based interventions and community services.

Students With Disabilities

Absences often connect directly to a student’s disability — medical conditions, anxiety, autism, and other diagnoses can produce attendance patterns that look like truancy on paper but aren’t the result of a child or family ignoring school.

Connecticut’s YSB referral guidance addresses this directly. For a student with an Individualized Education Program, the school should convene a Planning and Placement Team meeting before pursuing a truancy referral. The team should consider whether the absences relate to the disability and whether the current IEP adequately addresses attendance barriers.⁶ Under the Individuals with Disabilities Education Act and Section 504 of the Rehabilitation Act, students with qualifying disabilities are entitled to accommodations that can include flexible scheduling, homebound instruction, counseling, and transportation assistance. If absences stem from a disability-related need the school hasn’t accommodated, punitive truancy measures can create legal problems for the district rather than solving the attendance issue.

If you believe your child’s absences are tied to a disability, request a PPT or 504 meeting in writing before accepting a truancy referral path, and ask the team to document how the attendance pattern connects to the condition.
