ANSWER: Hello and thank you for your question. I would love to be able to simply list a few links for you but believe it or not, this is not a question with an easy answer.
First, I would like to advise you on what to avoid. Courses that are listed on sites that have large educational variety from website design to ancient astrology are best avoided. They list courses offered by individuals but have little knowledge themselves as to whether the content is valid and worthwhile so find it a struggle to ensure the content is quality. These kinds of courses are usually cheap and may well be great for a little bit of insight or maybe to fire your imagination and give you ideas of what to study but not as in-depth courses that will train you properly and responsibly.
To be honest, I have never studied any degrees of witchcraft online in this way, only using it to seek out information on individual aspects just as I have read books and listened to talks given by other practitioners about things I would like to learn or have found interesting or useful to my practice – but then the internet did not exist when I began on my path!
So how do you choose an online course? Look for either an individual or a coven who have plenty of real and good recommendations. Look through their content, does it seem reasonable for the level you’re working at and are you drawn to work with what they’re putting out? Don’t just settle for the results on page one of any internet search either, the better results for this undertaking will come on pages after that rather than the ones who have paid for their SEO or advertising. The ideal would be that you find a solitary practitioner looking for someone to mentor or a coven who will take you through the levels safely but I do understand the need to look into online avenues so here’s an example of a good course on Wicca, I cannot personally recommend it as I haven’t completed it myself but it looks like reasonable content and has plenty of good, real sounding reviews.
Of course, we have plenty of good information here on WitchPathForward too and will be expanding our offerings in the summer to include some courses and workshops so you can always keep on checking back here too!
I hope this helps,
