I could be wrong, and I'm sure someone will pop up with further info if I am, but I'm pretty sure no lash course that's 100% done at home is fully accredited - you get a certificate, but you're usually really limited for insurance as The Beauty Guild for example won't recognise it. It may say on their website that it's accredited, but double check who it's actually accredited by and what you get at the end of it.
If you want at home learning due to time restraints I'd recommend doing a one day course - it's usually just 5/6 hours followed by case studies at home in your own time.
