As well as being impractical, I would argue that training courses for parents are unnecessary. Mothers and fathers have been raising children without any formal help or official interference for thousands of years. Parenting skills are learnt from family members, friends, neighbours and the surrounding culture. Perhaps more importantly, adults learn to be good parents by instinct, by trial and error, and by getting to know their own children; for example, a good parent will try different strategies when faced with a badly-behaved child, and will gradually develop an understanding of what works to correct the behaviour. None of this requires the intervention of a taught course.

In conclusion, while compulsory parenting lessons might seem like a good idea, I believe that such a scheme would be unworkable and largely pointless.
