iGeneration Youth is a “for youth, by youth” online and print magazine. They are always looking for smart-thinking teens for brilliant storytelling. Our previous research indicated their features to be 900 to 1,200 words and shorter stories are 250 to 500 words, and that they paid $0.05 per word. It's not clear whether they're still publishing. You can try to contact them through social media or send your pitch directly; both their links and the pitch forms can be found on their main page.
