Schools are far more than mere exam factories. Across the UK, teachers in 32,000 schools and colleges care for children on over half the days in any given year. Or we did until the lockdown in March 2020. Since then, children have missed the best part of two full terms. And while they were out of our sight, some were at risk. Six year-old Arthur Labinjo-Hughes, for example, may have been rescued from the terrible abuse he suffered had his teachers been able to see him every day.
