Contrary to popular belief girls were hardly ever tawsed even in an all girls school in any part of the UK. The most common punishment for girls was an open handed smack either across the bottom or back of the legs.
The next most common would have been the slipper across knickers and the most severe, either hand strapping (but not with a tawse) or caning across the bottom.
Tawsing if at all was always across the hands. Usually only one stroke across each. I attended an all girls school and received just about every form of punishment mentioned above but never was tawsed.
