I have some vague thoughts on this sort of thing, but I only ran my EA-based club for about 6 months, and didn’t do any follow-up measurements. So I don’t think any of those thoughts would add much value relative to the High School EA Outreach post, the post SHIC Will Suspend Outreach Operations, and what you’ve already said/​thought.
So instead, here’s a grab bag of links that came to mind as potentially relevant and useful, if you hadn’t seen them already. (Though I’d guess that the collection of resources cafelow linked to may be more relevant and useful.)
