Testing ice on ponds

Dear Folks,
This is a practical question for Sudbury Valley School, but maybe
others have an answer too:
Some friends of mine have a pond for the first time this winter.
What is your procedure for checking the ice on the pond at SVS to see if
it is safe to skate on?
Thanks much,

Ithaca, NY
