To get a broader picture have a look at the intersting polls at:
Many received the tawse from 5 onwards and 50% from the age of 9.
Two or three tails was really cut teachers preferences. The poll shows 80% found two tailed the worst (it was the most common by far)
25% answering had received 6 strokes.
60% only received tawse in school, 3% only in home and 36 % both at home and school
It was banned in schools according to educational area, variously from 1982 to 1986
Hope this helps for starters
