[nabs-l] Locating a standard normal distribution table

Tue Feb 21 02:25:21 UTC 2012

Hi Dezman and all,
I have contact info for two people: Ruth Loew and Nora Hallenbeck, at
ETS who handle disability accommodations. Ruth can be reached at
rloew at ets.org
Nora can be reached at
nhallenbeck at ets.org
Ruth talks with NABS regularly, and she might still be on this list.
Best,
Arielle
