The 2015 IAPT Workforce Census Report, produced jointly by NHS England and Health Education England, offers the most comprehensive view to date of the size and shape of the IAPT workforce in England, providing insight into the capacity of IAPT services to offer the full range of NICE-recommended psychological therapies.

The results are being used to inform workforce planning discussions and future IAPT expansion by providing information about the current skill mix and skill gaps, retention and turnover of staff, as well as identifying staff groups who could benefit from IAPT training courses to increase capacity for the full range of therapies.
