Pros
Fellow employees. A Bachelors degree minimum is required to work as a Pearson "Peak Employee," as they are known, so everyone around you has a level of education higher than the average population. They know what I'm talking about, and I know what they're talking about. Low level of stress (most of the time) - you score achievement tests all day. Interesting mix of states - Pearson contracts with different state's departments of education to score that state's tests. Every state is slightly different in the way they want their tests scored.
Cons
Job is temporary. Facility is open and operational only as long as Pearson has tests to score, which is not the entire year. When the kids are out of school, and before the next year's tests start to come in (July thru Oct), there is no work. Work through the school year is sporadic, though management IS trying to bring work in to fill up the whole year.
