Longitudinal evidence is essential for phone-free school policies, especially evidence about sustained attention and fewer conflicts. Yet phone-free school policies also need formal responsibility: one coordinator, transparent scheduling and a short common report can prevent voluntary energy from masking repeated failures.

The value of phone-free school policies lies in participants shaping the activity themselves. I would protect consistent enforcement by limiting institutional controls around phone-free school policies; immediate enthusiasm is not proof, but it can create the relationships from which durable learning develops.

Evaluation of phone-free school policies becomes misleading when it reports only an average. The issue of students who rely on devices for translation or care requires separate evidence about who can attend, who supplies hidden labour and who needs additional support to participate.

I would not judge phone-free school policies from their launch figures. The real test is sustained attention and fewer conflicts, observed over several months and including withdrawals. For phone-free school policies, clear safety boundaries are compatible with consistent enforcement and do not require a large administrative structure.
