Narrowing it Down

Spent a couple of hours today deciphering my notes from the weekend and looking at the Web sites of three of the online test providers. Only three of the 7 currently disable the Web browser so that test takers cannot easily print the test questions. I think this is an essential element of any service we decide to buy. I also sent off a couple of e-mails to the 3 vendors asking a few questions. I want to judge their response time and quality as well as answer some missing or conflicting information from the their Web site. I have to get this narrowed down this week so I can get a report and recommendation done by September 1st...just 8 days away.
