The consensus around England's new pupil attendance targets sounds reasonable enough. Children need to be in classrooms. Truancy costs them academically. We should measure what matters. But this framework obscures a more uncomfortable question: what happens when we optimize schools for a metric that schools themselves cannot always control?

Let me be clear about the analysis first. The government's push for attendance accountability is not baseless. Research consistently shows correlation between attendance and attainment. Schools with chronic absenteeism face real challenges. If targets encourage headteachers to take absence seriously rather than accept it as inevitable, there is a legitimate case for measurement.

The comfortable position, held across most education commentary, stops there. Targets are good. Accountability is necessary. What could go wrong?

But dig slightly deeper and the framework begins to strain. Schools cannot unilaterally solve the reasons children do not show up. A child kept home because parents cannot afford breakfast arrives at a different problem than a child with untreated anxiety. A teenager caring for a sick sibling faces constraints distinct from one skipping lessons out of boredom. Yet all register identically as absent.

The real concern is what happens next. When institutions face metrics they cannot fully influence, two patterns emerge. The first is perverse optimization: schools may push out difficult cases to improve headline numbers, or reclassify absence rather than address it. The second is demoralization: staff blamed for societal failures outside school walls.

This is not speculative. We have seen it before. When NHS trusts faced waiting-time targets, some gamed the system by moving patients between lists. When universities faced research output metrics, publication inflation followed. When teachers faced pupil progress targets divorced from student circumstances, teaching to tests intensified. Measurement often improves what it measures at the cost of what it ignores.

The deeper fracture is this: attendance targets treat the symptom as though it were the disease. A child absent from school is not the root problem. The root problem is why attendance requires compulsion in the first place.

In functioning systems, children attend because school is where they need to be. They learn things. They see friends. Teachers notice when they slip. Parents understand the value proposition. Attendance becomes self-reinforcing. You do not need targets in that scenario.

Attendance targets become necessary precisely when those conditions fail. They are a sign that something upstream is broken. Yet policy responds by tightening the metric rather than investigating what schools cannot do alone.

What breaks next, if this logic holds? School funding will likely follow attendance patterns, creating perverse incentives for already under-resourced institutions. Mental health support, which drives absence, will face pressure to exist elsewhere so schools can claim credit for improvement. And the adolescents genuinely struggling will find themselves managed through institutional pressure rather than genuinely helped.

This is not an argument for ignoring attendance. It is an argument that measuring absence without addressing causation is like treating a fever without investigating the infection.

The harder question is whether government actually wants to know what drives absence. Because the honest answer involves poverty, parental stress, insufficient mental health services, and bullying. These are expensive. Attendance targets are cheap. They create the appearance of action without requiring the infrastructure that would make targets unnecessary.

Schools should track attendance closely. But as an internal diagnostic tool, not a performance league table. The moment measurement becomes public accountability, institutional incentives shift away from solving the actual problem.

If we genuinely cared about why children do not attend school, we would fund the things that make attendance unnecessary: counselors, breakfast programs, transport, safe learning environments. Instead we are raising the bar and hoping schools clear it.

The consensus assumes schools can solve this alone. The better question is whether our system is set up so they can.
