It is now a requirement that all doctors complete level 1 training yearly, and at least Level 2 training every 3 years:
Level 1: Watch the held by all practices
Level 2: Complete the training via this link every 3 years: http://courses.econstruct.co.
This is a requirement every 3 years.
Every year you will need to refresh at Level 1. This is by way of watching a DVD, available via most practices if you are a salaried doctor or long term locum, or the Exeter sessional group currently has a DVD which people can borrow.
