A vast number of skills and level of experience are valued at board level. It is not just those with board experience who get appointed to boards.
It may surprise you to know that the majority of new board appointments have neither past NED experience nor were/are CEOs.
People incorrectly think that they don’t have the right level of skills or experience to sit on boards. This is untrue if you are clear on what sort of board you would like to sit on.
