Irish healthcare has seen radical reforms in recent years. Regulatory Body Registration was introduced to improve patient care and regulate professionals. Continuing Professional Development (CPD) is a requirement of registration. Professionals need to keep up-to-date with new techniques and technologies while maintaining their skills.

This research assessed the factors affecting CPD participation in Radiation Therapists and Diagnostic Radiographers and their knowledge and attitudes towards Regulatory Body Registration.

Online surveys were designed and made available on the Irish Institute of Radiography and Radiation Therapy (IIRRT) Website for IIRRT members. The responses were analysed using descriptive statistics and χ2 tests in a statistical computer programme.

Personal development, time, cost and staff shortages negatively affect CPD participation. Reflective practise is not a barrier to CPD. Knowledge and attitudes to Regulatory Body Registration varied.

CPD must be developed in Radiation Therapy and Diagnostic Radiography. Funding, time and increased staffing could result in effective implementation of CPD. Regulatory Body Registration has been communicated but more information regarding the process is required.
