(2-part post):
I assume that you mean standing for election to the board of governors for a school. If so, you write (within reason!) whatever you think is likely to impress the people casting their votes.
Here's a (very) rough example, off the top of my head:
"In seeking election to the board of governors, I know that I will be taking on a very time-consuming task which requires a great deal of study of policy documents and relevant regulations. However, I believe that my experience in leading the team at Bogshire County Council's planning department equips me well for these aspects of the job. Additionally, my work as a youth club leader has given me an insight into the needs and concerns of young people.
I have two children already in the school. (My son is in year 8 and my oldest daughter in Year 10). My youngest daughter is due to join the school in one year's time. I recognise that the school has an excellent head and teaching team, who deserve the maximum support from the school's governors. If elected to the position of governor, I would hope to be able to regularly spend some time in the school, during the working day, so that I can learn more about the needs of the staff and pupils. However, I recognise that teachers are professionals who know far more about the day-to-day job than I could ever do. So, while seeking the knowledge to help me in my work as a governor, I would never try to interfere in the daily work of the school.
