Your specific idea for an entrepreneurship training programme for high-schoolers sounds like a really interesting one.
I’m somewhat sceptical that such a programme targeting high-schoolers is the right approach to solving this skill gap though. The entrepreneurship gap seems like an important but difficult one to solve (eg. see Longtermist Entrepreneurship Project). Charity Entrepreneurship has had success in this area, but they’ve typically targeted graduates & people further along in their career. I would imagine that most high-schoolers would neither be in a position to found an organisation right away or have the necessary skills to do so.
It’s definitely possible that such a programme could help develop skills for high-schoolers (perhaps even by founding and running their own small-scale project) in the hope that they’d later use these to found an organisation. However, in this case, it seems very difficult to assess the success of the programme (as the feedback loops would be quite long) and I’d suspect that very few trainees would ultimately go on to found high impact organisations.
I definitely could be wrong here though and would be interested to hear your thoughts?
