My brother like our late dad is left handed. My dad was forced at school to use his right hand which as a result he was ambidextrous. The junior school I attended also tried to force my brother to use his right hand, when my father found out he went ballistic, storming up to the headmasters office. That was the end of any attempts by the school to force left handed pupils to use their right hands. When it was my turn to go up to junior school the staff seemed relieved to discover that I was right handed.
