Are there any changes for this CPD period (which is from July 2019) compared to previously?

In the previous period (ending 30 June 2019) those farm RAMAs who qualified under the “old” (pre-April 2017) syllabus had to do a compulsory module on farm animal parasite control and resistance. That was a one-off requirement: there are no compulsory modules in the current (July 2019 to June 2021) CPD period.
