A Pearson Vue customer takes a test like the CompTIA Network test in the hope of furthering their career. They spend the time and money to take the test for their own benefit, not for Pearson Vue's benefit. Pearson Vue profits from that hope and expectation.
Pearson Vue requires a survey in order to obtain demographics and test prep info in order to better provide and market their services, for THEIR own benefit.
Would the claimant have gone to this test center solely to provide them with this information? Of course not. If Pearson Vue had required this information, they should have paid for it through a market research company.
The claimant read all the information carefully and was aware before the test began that they would be required to take a separate survey once the test was concluded. They completed the test, which they could not revisit, but was unable to complete the survey for Pearson Vue's benefit before visiting the bathroom.
I would strongly suspect that a refusal to allow someone with a heart condition to visit the bathroom as necessary, due to meds, violates the ADA. If the student had needed bathroom access during the test, suitable accommodation might have had to be arranged in advance. But they didn't need to.
Furthermore, Pearson Vue is requiring their customer to work for them. Can they withhold a product until the customer has completed work for them? I'd be interested to find out.
My recommendation to Pearson Vue is that they provide their customer with their test results post-haste. Otherwise we're into "**** around and find out" territory.
If the customer does not receive an immediate release of their results (and/or a refund/do-over if the customer is willing to accept that) I would suggest they file complaints with the ADA, the FTC, their state Attorney General, and just for fun, Wage and Hour.
And if those results don't come fast enough, take it to Small Claims, setting out the lines of argument as above.
This is one that almost makes me wish I wasn't retired.
