From the
NCRC page:
The NCRC will be awarding three $330 scholarships to help students attend the national weeklong seminar at Park City, KY July 24-August 1, 2015. To be considered please send a caving resume, 2 letters of support from NSS members, and a cover letter describing your financial need and how training would benefit the caving community in your region. Letters from grotto officers will be given the most weight. Letters from Regional Coordinators will be given less weight.
Submit your information to Roger Mortimer, 1455 N. Echo Avenue, Fresno, CA, 93728.
All materials may be submitted electronically to
ncrc-scholarship@sbcglobal.com All materials must arrive by April 26, 2015 to be considered.
Awards will be announced by May 26, 2015.
I see no requirement to be an NSS member to apply. However, you do need to be an NSS member to attend. (There's a "non-nss" option, but I believe it's like $100 so it costs more than joining the NSS.)
But Roger is the person to say for sure.
