A Texas parent can hear two very different warnings in the same semester: “Your child may lose credit for this class” and “Your child has too many unexcused absences.” Both warnings are real, but they come from two separate systems in Texas law, and confusing them is easy. One system protects class credit, and the other enforces compulsory attendance. Knowing which rule applies — and which count a school is using — tells a family exactly how much room it has left.
Quick Answer
Texas runs two absence limits side by side. For class credit, a student in kindergarten through grade 12 must attend at least 90 percent of the days a class is offered, or the credit can be withheld; in a typical 180-day year that means missing more than about 18 days of a class puts credit at risk. Separately, for unexcused absences, three days or parts of days missed without an excuse in a four-week period trigger a warning notice and truancy prevention measures, and ten or more unexcused days or parts of days within six months can lead to a truancy court referral.
The Key Numbers at a Glance
| Rule | The limit | What it affects |
|---|---|---|
| Attendance for credit (the 90% rule) | Attend at least 90% of the days a class is offered | Class credit or final grade |
| Lower edge of the credit rule | 75% to 90% attendance | Credit possible through a principal-approved plan |
| Truancy prevention trigger | 3 unexcused days or parts of days in 4 weeks | Warning notice, conference, prevention measures |
| Court referral trigger | 10 or more unexcused days or parts of days in 6 months | Possible truancy court referral and parent prosecution |
The two tracks count absences differently, which is the part that surprises most families. The credit rule counts nearly every absence, excused or not. The truancy track counts only unexcused absences, but it counts parts of days too, so leaving early or arriving very late can add up. The Texas Education Agency’s legal guidance on attendance enforcement walks through both sections of the Texas Education Code side by side.
The 90 Percent Rule, Explained
Section 25.092 of the Texas Education Code conditions credit on presence: a student may not receive credit or a final grade for a class unless the student attends at least 90 percent of the days the class is offered. The rule applies from kindergarten through grade 12, and it applies even when the absences were excused — a long illness, for example, can still pull a student below 90 percent. Only absences the state specifically exempts, such as a religious holy day or a required court appearance, are left out of the count, and districts handle the details through local policy.
The math is simple. In a 180-day school year, 10 percent equals 18 days, so a student who misses 19 days of a year-long class has fallen below the line. For a one-semester class of about 90 days, the same rule cuts the allowance roughly in half, to about 9 days. Families who want to watch the number before it becomes a problem can estimate their standing with the attendance percentage calculator on this site, which is the same figure schools are watching from the other side.
Falling below 90 percent does not automatically erase a grade. A student whose attendance lands between 75 and 90 percent may still earn credit by completing a plan approved by the principal that lets the student meet the instructional requirements of the class. Attendance below the 75 percent mark, or a case the plan does not resolve, goes to a campus attendance committee, which can grant credit when extenuating circumstances explain the absences.
Excused vs Unexcused Absences in Texas
For the truancy track, only unexcused absences count, so the definition matters. Under Section 25.087, a student may be excused for a temporary absence for any cause the teacher, principal, or superintendent finds acceptable, and state law requires districts to excuse certain absences outright: observing a religious holy day, attending a required court appearance, completing citizenship paperwork or taking part in a naturalization ceremony, serving as an election clerk, and visiting a health care professional when the student attends school before or after the appointment that day. Districts may also excuse up to two days in the junior year and two in the senior year for college visits.
Anything outside those categories — a family trip, oversleeping, a note the campus does not accept — risks landing in the unexcused column. Parents comparing states will find that the same two-column logic appears across the country, although the numbers change; the guide to how many unexcused absences are allowed in school explains the general pattern behind these state rules.
What Happens, Step by Step, When Unexcused Absences Build
Texas law lays out an escalating sequence, and schools must follow the early steps before anything reaches a courtroom.
- Three unexcused days or parts of days in four weeks. The district must notify the parent in writing, remind the parent of the duty to monitor attendance, request a conference, and place the student under truancy prevention measures.
- Truancy prevention measures. These can include a behavior improvement plan, school-based community service, counseling, mediation, or other supports the district chooses. The goal at this stage is correction, not punishment.
- Ten or more unexcused days or parts of days within six months. The parent becomes subject to prosecution for failing to require attendance, and a student between the ages of 12 and 18 may be referred to truancy court for truant conduct.
Compulsory attendance itself runs from age 6 until a student’s 19th birthday, and a younger child who is enrolled in prekindergarten or kindergarten is expected to attend once enrolled. Tardies, on their own, are generally not treated as absences for compulsory attendance enforcement, but missing part of a day still counts as a part-day absence on the truancy track.
How Texas Compares With Other States
Texas is unusual in pairing a credit rule with a truancy rule. Many states set only a truancy threshold and leave credit decisions to districts. North Carolina, for example, lets local boards set the absence limits that trigger interventions, as the breakdown of absences allowed in NC schools shows. Ohio works through district policies built around hours missed rather than a statewide day count, which the guide to absences allowed in Ohio schools explains in detail. Families moving into Texas from either state often find the 90 percent credit rule is the part that catches them off guard.
Practical Tips for Texas Parents
- Send documentation the same day. A doctor’s note or a parent note delivered promptly is far easier for a campus to accept than one produced weeks later.
- Watch partial days. Leaving at midday for an appointment the campus does not excuse still counts as a part-day absence on the truancy track.
- Ask which count the school is using. A letter about credit and a letter about truancy come from different rules; asking the attendance clerk which one applies clears up most confusion.
- Check the percentage early. Once a student’s attendance in any class drifts toward 90 percent, a conversation with the campus is much easier than an appeal to the attendance committee later.
Frequently Asked Questions
Does the 90 percent rule count excused absences?
Yes, in most cases. The credit rule looks at total attendance, so excused absences for illness or family reasons still count toward the 10 percent a student may miss. Only absences the state specifically exempts, such as religious holy days and required court appearances, are excluded from the count.
How many days can a student miss in a one-semester class?
Roughly nine. A semester class usually meets for about 90 days, and 10 percent of 90 is 9, so a tenth absence in that class puts the student below 90 percent attendance for it. The exact number depends on how many days the class actually meets.
What age does compulsory attendance cover in Texas?
School is compulsory from age 6 until a student’s 19th birthday, unless an exemption applies. A child younger than 6 who is enrolled in prekindergarten or kindergarten is also expected to attend regularly once enrolled.
Do tardies count as absences in Texas?
A tardy by itself is generally not counted as an absence for compulsory attendance enforcement. However, arriving extremely late or leaving early can be recorded as a part-day absence, and part-day absences do count toward the three-in-four-weeks and ten-in-six-months truancy triggers.
What happens if attendance falls between 75 and 90 percent?
The student can still receive credit by completing a plan approved by the principal that covers the instructional requirements of the class. If attendance falls below 75 percent, the campus attendance committee reviews the case and may grant credit when extenuating circumstances are documented.
The Bottom Line
In Texas, “allowed absences” really means two allowances: miss no more than about ten percent of any class if the credit matters, and keep unexcused absences under three in any four-week stretch to stay clear of the truancy process. Parents who track both numbers rarely get surprised by either letter. The free tools on Attendance Percentage Calculator make the first number easy to check at any point in the semester.
