Pros
work from home (online); most scoring leaders (not content scoring leaders) are competent and pleasant to work with; can get fair amount of hours for a part-time job
Cons
content scoring leaders and administration are incompetent and rude-- more concerned with ego than accuracy/fairness; constant buck-passing by content scoring leaders and administration; "don't bother me" management style; little monitoring of supervisors, so you need to either suck it up and focus on the few pros of the position, or look elsewhere for part-time positions (there are other companies-- Pearson, McGraw Hill, etc.-- who are finally in competition with ETS); ETS makes enormous earnings and their "not-for-profit" status has been ridiculed by more than one analyzing organization
