Im sorry I don't know what the goals is either other than as a yes or no to say the project has them and maybe for the assessments = would mean they have the quality assessment categories and functionality on their banners. Thats just a guess though. As far as the Maine question some of the state projects and several of the other US related projects do not have assessment carteories but I thought maine did. If you look at the Embassy page @ Wikipedia:WikiProject United States all the US related projects are listed (that doesn't mean that they fall under WPUS just a list of whats out there), their status and a link to the Assessment tables. Not sure if that will help but maybe it will.
