Some charter school governing boards meet too often and for too long. If a charter school board meets more than once a month they're probably getting involved in too much at the school. Moreover, board meetings should not go past 10 p.m. It's unlikely parents can stay after 10:00 and the board members can't make good decisions that late. Plus, it's hard to find people who are willing to serve on the board when it impacts their being able to get up for work the following day. Not to mention the charter school administration needs to be at the school bright and early the following day!
There are common mistakes that charter school boards make. Well-meaning parents get too involved when they start the habit of going in to the school office when they drive carpool. The more they hear about, the more they like to involve themselves. The best advice is to physically limit the time associated with school activities.
