I wasn’t a parent governor, but I was a governor for many years.
As others say, you are not a representative for other parents. No complaints come through you. You are there to make a contribution as a parent.
The Government produces a Governance handbook - it’s a downloadable tome but covers everything. Try and have a look. It’s the bible.
It makes a huge difference if the GB is well run and effective. Everyone needs to be trained and pull their weight. It does take some time to get up to speed, especially with data interpretation and any specialist role you might take on, eg send governor, PP governor etc.
A parent governor should not directly report views of individual parents. They have no mandate for this. The role is strategic. Parental opinions are almost certainly operational however a parent governor has a unique position to think as a parent. This is what’s required.
There can be big decisions such as choosing a new head, but your main role is to question data and info you are given by to ensure the school is the best it can be for the Dc. The school must have a strategic vision and improvement plan and governors should monitor them. You might performance manage the head. The term “critical friend”, I think, is outdated. Governors are tasked with having a professional business relationship with the head. Governing boards should ensure they appoint governors with suitable skills - so think about what yours are.
Definitely ask for a meeting with the chair to see how they run the GB. Look at minutes. Talk about what they do and how they do it - so realistic commitment, meetings and visits to school, training, committees you could be on etc. Try and find out about how they cover the 6 key features of effective governance - if you know what they are, you are on your way!!
