“The schools that catch those signals early are the ones that keep their students.” That observation, from a school behaviour platform chief executive commenting on new survey data, captures the heart of a quiet but significant change in Oklahoma. Starting with the 2025-26 school year, the state no longer judges schools on whether their chronic absenteeism rates rise or fall. Lawmakers removed that indicator from the state’s A-F accountability system and replaced it with a measure of instructional time. The announcement of the change, carried on October 26, 2026, has drawn attention well beyond Oklahoma, because it raises a question every school system faces: what should a school be graded on, the absences it records, or the learning time it protects?
The answer Oklahoma has chosen is more subtle than a simple swap. The compulsory attendance law has not changed, and the daily reality of tracking who is in class has not changed either. What changed is the grade. A school’s report card no longer moves up or down with its chronic absenteeism rate, but the instructional-time measure now in its place is driven by the same daily pattern schools have always watched: whether students are in their seats, on time, and ready to learn. For parents, teachers and school leaders, the practical message is therefore easy to misread. The grade changed, but the underlying work did not.
The old report card versus the new one
The clearest way to understand the change is to set the old and new systems side by side. Under the old approach, a school’s A-F grade reflected, among other indicators, whether its chronic absenteeism rate was moving in the right direction. Under the new approach, that indicator is gone, and instructional time takes its place. The table below summarises what shifted and what did not.
| Element | Before the change | After the change |
|---|---|---|
| Chronic absenteeism in the A-F grade | Counted as an accountability indicator | Removed from the A-F system |
| Instructional time in the A-F grade | Not the replacement measure | Now the measure used in its place |
| Compulsory attendance law | In force | Unchanged |
| Daily attendance tracking | Required | Still the foundation of the new measure |
For many superintendents, the removal of the absenteeism indicator came as a relief. Chronic absenteeism is shaped by forces far beyond a school’s gates: illness, transport problems, family circumstances and community conditions all feed into it, and school leaders have long argued that a single school cannot control all of them. An accountability grade that rises or falls on that number can feel like a judgement on conditions a school did not create. Instructional time, by contrast, is closer to what a school directly manages: the hours of teaching it actually delivers, and whether students are present to receive them.
That distinction, however, should not be overstated. Instructional time is not created out of thin air. It is the product of students arriving, settling and staying in class, and every minute lost to a late arrival or an empty seat is a minute of instructional time that cannot be recovered. The two measures therefore overlap far more than the headline suggests. A school that lets tardiness drift will see its instructional time suffer just as surely as its absenteeism figures once did, even though the report card no longer names absenteeism as the reason. The original announcement of the change is set out in the Oklahoma instructional time report, which links the policy shift to fresh survey data on tardiness.
Why tardiness became the warning light
The survey data behind the announcement helps explain why school leaders are paying attention to tardiness even as the grading formula changes. Across four national education conferences in 2026, thousands of school leaders were asked about their biggest student behaviour challenges, and the same two issues led the conversation everywhere: attendance and tardiness together accounted for more than half of all responses at the largest events, nearly double every other challenge combined. Tardiness ranked first among Texas secondary principals surveyed at one summer workshop, with attendance second, and hallway loitering close behind.
The reason tardiness matters so much is that it is an early signal. A student who is chronically late is not yet chronically absent, but the pattern is already forming: one missed period at a time, one late arrival after another, until the drift becomes visible in the absence data weeks later. School leaders quoted in the announcement describe tardies and hallway loitering not as daily frustrations but as leading indicators, the first signs of a student slowly disconnecting from school. By the time a student crosses into chronic absence, the warning signs have usually been visible for weeks, and the chance to intervene early has narrowed.
A second survey finding sharpens the point. More than a third of school leaders surveyed nationally cited the absence of a consistent tardy policy as their biggest challenge: different rules in different classrooms, applied differently by different teachers. When students learn that being late carries no consistent consequence, the drift that follows is predictable. Inconsistency, in other words, is itself a policy, and it teaches students that punctuality is optional. Schools that struggle with tardiness often struggle first with consistency, and the data suggests that fixing the rulebook matters as much as fixing the timetable.
Two campuses that changed the pattern
The announcement illustrates the point with two campuses that confronted tardiness directly. At Mustang High School in Oklahoma, a campus of 4,000 students, the head principal made hallway behaviour and tardies the first priority. Teachers welcomed the shift, students began reaching class on time, and the school then added recognition on top of the new consistency: students could earn points and rewards for good behaviour, and the principal described surprise at how eagerly students responded to earning that recognition. The culture of the hallways, in that account, changed because the expectations became clear and the good behaviour became visible.
A second example comes from Midland Lee High School in Texas, where the principal had previously tracked tardies in a spreadsheet, with administrators learning of a problem only after a student had accumulated three tardies with a single teacher. The missing piece, in that principal’s words, was student accountability: without a consistent system, late arrivals became an overwhelming daily headache. After a consistent policy was put in place, the school reported no tardies after lunch, a striking result at a school with an open-campus lunch programme. Students pushed back at first, the principal said, but then bought into the system, partly because recognition for good behaviour was built into it.
Neither story is about a grading formula. Both are about daily routines: a clear rule, applied the same way in every classroom, noticed quickly, and paired with recognition when students meet it. That is the work Oklahoma’s new measure still depends on, even though the report card no longer carries the absenteeism label. A school can no longer lose grade points for its absenteeism rate, but it can still lose instructional time to the same hallway drift, and the campuses that close that gap early are the ones that will not need a grade to know they are ahead of it.
What instructional time actually measures
Instructional time, as a concept, is simple: it is the time students actually spend in learning, as opposed to the time a timetable says they should. A school day can look full on paper while leaking minutes in practice, through late starts, slow transitions between classes, and students drifting in after the bell. An instructional-time measure tries to capture the reality rather than the plan, rewarding schools that protect the minutes they have and exposing the schools where those minutes quietly disappear.
That makes it a demanding measure in its own way. A school cannot improve its instructional time by reclassifying absences or by changing how it reports them; it can only improve it by getting students into class and keeping them there. The daily signal is identical to the one the old system watched, which is why the announcement stresses that the accountability formula changed while the underlying problem did not. Parents reading a school’s new grade should therefore ask a practical question rather than a statistical one: are students in class, on time, and learning for the full day, or is the day leaking minutes that no grade can restore?
There is also a fairness argument in favour of the new measure. Chronic absenteeism rates can punish schools serving communities where transport, health and housing pressures make attendance harder, even when the school itself is doing strong work. Instructional time keeps the focus on what happens inside the building once students arrive, which is closer to the school’s own contribution. Critics of the old indicator would say that is a fairer test. Supporters of keeping absenteeism visible would reply that removing it from the grade risks removing it from attention, and that a problem no longer graded is a problem more easily ignored. Both concerns are legitimate, and the real test of Oklahoma’s change will be whether schools keep watching the early signals even when the grade no longer forces them to.
A practical checklist for schools watching the early signals
For school leaders, parents and teachers, the Oklahoma change offers a useful checklist that does not depend on any single state’s formula. The steps below draw on the patterns described in the announcement and apply anywhere tardiness and absence are drifting upward.
- Write one tardy policy and apply it in every classroom, so that students meet the same expectation whichever teacher they face.
- Track tardies daily rather than waiting for a threshold, since a student who has already accumulated several late arrivals has been signalling for weeks.
- Treat the first repeated late arrival as a conversation, not a confrontation, asking what is making mornings difficult before the pattern hardens.
- Make good attendance visible through recognition, since the campuses in the announcement found that students responded strongly to earning points and rewards.
- Review hallway and transition patterns weekly, because slow movement between classes is often where instructional minutes are lost.
- Share the picture with families early, so that parents hear about a drift while it is still a handful of late arrivals rather than a term of absences.
Parents, for their part, can use the same lens at home. A child who is regularly late to first period is sending the same early signal as a school with a hallway problem, and the remedy is usually practical: an earlier start, a simpler morning routine, or a conversation with the school about transport or timetable clashes. Families who want to understand how attendance rules interact with school visits should also know that attendance laws and school procedures vary by state, and guidance on what a truancy officer can do and what a truancy officer does day to day can help parents separate rumour from procedure. For the arithmetic itself, a guide to calculating average attendance shows how schools turn daily registers into the rates that once fed the grade.
What this means for parents and students
For families in Oklahoma, the immediate message is reassuring on one point and unchanged on another. The reassuring point is that a school will no longer be graded down simply because its absenteeism rate moves the wrong way, which removes one source of pressure from school leaders. The unchanged point matters more: the compulsory attendance law still applies, and students are still expected to attend school and arrive on time. A change in the grading formula is not a change in the law, and it is not permission to treat attendance as optional.
For students, the practical advice is unchanged as well. Arriving on time protects learning in a way that catching up later rarely replaces, because the first minutes of a lesson often carry the instructions for everything that follows. A student who drifts into chronic lateness is not only losing minutes; the student is also losing the habit of starting on time, and habits, once formed, are harder to rebuild than a single missed lesson is to catch up. The schools that recognised good attendance, in the examples above, understood this: they treated punctuality as a habit worth rewarding, not merely a rule worth enforcing.
For other states watching Oklahoma, the experiment will be judged on outcomes rather than intentions. If instructional time rises and tardiness falls, the change will look like a smarter measure. If tardiness and absence rise while grades stay steady, the change will look like a blind spot. Either way, the lesson for every school system is already clear from the survey data: the warning signs appear long before the absence statistics do, and the schools that act on tardiness early are the schools that keep their students.
Questions parents and school leaders are asking
What exactly did Oklahoma change?
Oklahoma removed chronic absenteeism from its A-F school accountability system starting with the 2025-26 school year and replaced it with a measure of instructional time.
Does the change mean attendance no longer matters in Oklahoma?
No. The compulsory attendance law is unchanged, and the instructional-time measure itself depends on students being in class, so daily attendance tracking remains essential.
Why do school leaders focus on tardiness?
Survey data from 2026 shows attendance and tardiness together leading school leaders’ behaviour concerns, and tardiness is seen as an early warning sign that appears weeks before a student becomes chronically absent.
What is instructional time?
Instructional time is the time students actually spend learning in class, as opposed to the time a timetable allocates, and it falls when late arrivals and slow transitions eat into the school day.
What can schools do about rising tardiness?
Schools can apply one consistent tardy policy in every classroom, track tardies daily, intervene at the first repeated pattern, recognise good attendance, and review hallway transitions so that instructional minutes are protected.
