There are a number of tasks that a student council secretary is responsible for. He or she will be responsible for something which is called 'taking minutes'.
This means that anything that is discussed while the student meetings are taking place should be noted accordingly. It could be about student cuts, plans to demonstrate about taxes or intentions to start up a student radio station. These are all possible factors that should be taken into account.
After all the discussions and debates have been noted down, it is then up to the secretary to take these notes and compose a one to two page document of a summary of what has taken place in the previous meeting. People can then refer to this in the next meeting.
Another major responsibility is to create and distribute marketing material. This could be done in the form of newsletters or leaflets highlighting all the main objectives of the students, any student events that might be taking place on the campus as well as any other important things that will involve the student union as a whole.
This is crucial because the student union can be informed and up to date on what is happening on campus as well as extra-curricular activities.
You will also have the opportunity to contribute ideas to the meetings as well as for the newsletters and any schemes that students might want to be involved in. This could be anything from agreeing affiliate discounts for students in clothes stores and pizza places to help them or advising the president of the student council on matters they are involved in.
