Staff costs
Source - Oxford Economics & CIPD (2022): The average cost of replacing a UK employee is estimated at ~£30,000, comprising £3,500-£5,000 in direct recruitment & onboarding costs, plus ~£22,000 in lost productivity over the 6 months it typically takes a new employee to reach full effectiveness. Retention, wellbeing and mental health costs are additional.
Student costs
Every complex attendance case represents 30-60 hours of staff time per year. A single pupil with complex mental health needs can require over 100 hours of staff time annually - costing up to £12,000 when factoring in leadership time, wider disruption and staff impact.
