Is this B2B or B2C (abroad)?

Hello. I sell a package of literacy training, resources and support and business has been growing outside the UK. Most of the time it's straightforward: If a mum buys it to use with her kids, I charge VAT. (B2C) If a school or sole trader tutor buys it, I don't charge VAT. (B2B) Where I'm stuck is when a teacher buys it to use only in their place of work. They might eventually be reimbursed or they might not. I've been charging them VAT but giving a discount and absorbing the cost myself because they're least likely to be able to afford it. Any thoughts? Thanks!

Please see the guidance below which explains the Place Of Supply Treatment for training/education where the trianing is in a classroom or where the trainer is in one country and the customer is in another country:
