Groups can mount effective actions simply by attending the public meetings of government committees and boards. To be effective the group needs to bring a substantial number of its members and plan what will be said and who will say it. In the best circumstances, a group will demonstrate strength in numbers and articulate a clear and persuasive message.
Attending public meetings can be especially effective on the local level where meetings - say, municipal school board hearings - are often sparsely attended. Simply attending may be enough to get a group's concerns on the radar of decision makers. One or a few members of an interest group may attend a public meeting to gather information or to weigh in with members' views. If the group's members are a majority of all those attending, the message is even stronger.
