Tenderfoot was the name given to new recruits to a Guide unit, in the weeks before their Promise Ceremony. It was a literal term which had been adopted - it would take time for them to learn the basic skills needed to become a Guide, which they would work on during their first few weeks, at the same time as deciding whether or not to become members of the Guide unit.
In 1912 the tests were:
Know the signs and salute, and the three promises.
Know the composition of the Union Jack, and he right way to fly it.
Tie four of the following knots: Reef, sheet bend, clove hitch, bowline, fisherman's, and sheepshank.
