Continuing professional development (CPD) is voluntary training you can take to keep your skills up to date - you decide how you do it and pay any costs involved.
As an approved driving instructor (ADI), you can take CPD in different ways. You can:
update your teaching or driving skills - find driving instructor training courses
go to local or national meetings or seminars
research new vehicles for your business
spend time developing your business skills
go on formal courses
spend time on the internet carrying out research
network with other driver trainers
