John:

I think that the degree to which your rule making spurs new candidates (and renewals, as 

Gail suggests) will determine the percentage of companies with the qualified testers and not 

whether SES or ETA will be a bottleneck. ETA is the only company contracted to conduct 

the QSTI/QSTO exams for SES (i.e., register candidates, prepare the paperwork, and grade 

the exams). ETA hires proctors wherever needed so there is a good deal of flexibility and 

capacity if the demand is there. SES is responsible for the exam questions and for 

reviewing and acting on applications. SES can manage, review, and act on large number of 

applications; we have done that before. I think SES and ETA have the capacity to handle an 

increased number of requests, even a dramatic increase.

Gail,

Thanks. I noticed that many companies are listed several times because they have more 

than one QSTI. When I remove the duplicate listings, I get about 110 companies. If there 

are about 400 stack test companies in the U.S., then about 28% of U.S. stack test 

companies have at least one QSTI at the present time.

How high a percentage of companies with at least one QSTI can we get by about May 2011?

We just posted an updated list on the SES website (I'm attaching that list), and there are 

256 companies listed. This isn't the most complete list because, again, people have to 

contact us to get on the list. I know of at least one or two new companies that are not 

on this list as yet. In talking with Mike Hartman, he thinks there is about 400 companies 

with about 4000 total people in the US.

If you wish, I can go through my database and give you a number for companies that 

have at least one QSTI, even for those not listed on the website. I won't give you 

company names, just the number.

Subject: Number of Stack Test Companies

Gail,

I'm preparing a response to comments document for the AETB/PGVP proposed rule. Could 

you please tell me the approximate number of stack test companies in the U.S.? I'm trying 

to calculate the approximate percentage of AETBs with at least one QSTI. It looks like there 

are 110 companies listed on the SES web site that have at least one QSTI (I know that this 

is probably an underestimate because not everyone wanted their name posted).

Thanks
