Hello all, First-time poster here. I was just wondering if anyone knew of any "tutor training" courses (online or otherwise) out there? The only education certificate I hold is a CELTA qualification, but that was many years ago and I would like to pick up my professional development where I left off. I've tutored languages informally for friends and acquaintances on and off, but now I'd like to learn more about how to deliver private classes properly. Thank you in advance for your time.
