I am a leader at my company where I manage a team that includes a lot of members where English isn't their first language. Specifically many speak Dari (Afghan language with similarity to Persian).
Many of my employees have expressed interest in resources for learning English from Dari. I want to know if there are any e-books, audio, or courses that folks might find worthwhile. I'm looking myself but finding it hard to evaluate what might be most useful given I can't really assess if the books I'm finding are accurate because Dari is not my native language.
I'm also looking for local library resources (like Mango Languages or Transparent Language) but wanted to ask others if they have any advice I can use to help folks. Thank you.
