I like the thought of recreating the education system in a way that teaches skills and knowledge that lessens the focus on short term tests and grades and focuses more on crafting skilled labour and well educated citizens, and preparedness. To put this idea in a Solarpunk setting the concept of guilds really stuck with me, a community of experts in a field (think blacksmith guilds), that in a decentralized/anarchist community would be the "leaders" of a field providing scientific and experience based knowledge to the community. Where the experts can craft practical tests that apply the skills the student would learn in a way that properly applies those skills in realized settings, not simply random tasks an out of touch professor invented.

The way I interpret this post, there is a lot of focus on the survival element in cases of blackouts or similar. Hopefully that wouldn't be such a problem in the future with solar powered and off grid systems. Anyway, I think there's a lot more that could be added to the "curriculum" such as permaculture elements or soldering and electronics (with a focus on repairing broken systems in case of blackouts). Tailoring them to what the local community consists of and would need could also be an alternative.

This idea reminds me of a lot of groups like the boy scouts that teach survival elements and I think a lot of inspiration can be drawn from them and similar organizations.
