Witch School is a real thing!
Wicca is a contemporary pagan new religious movement developed in England by Gerald Gardner, a retired British civil servant, and introduced to the public in 1954. A duotheistic religion, it worships a goddess and a god - the Moon Goddess and the Horned God respectively. Wicca is based on older nature-worshipping pagan practices: Druidism, Shamanism, Heathenism, and others.
Though denounced by some Christians and adherents of other major religions as wrong on every level, Wicca actually teaches some pretty sensible values and ideas, such as “As within, so without”, meaning that what you cultivate within yourself will manifest itself in the outside world in your actions. Another core principle is “An it harm none, do as you will”, or as long as you aren’t doing any harm, do whatever you like. It’s quite refreshing really.
The word Wicca comes from Old English wicca meaning wizard or sorcerer. The feminine form was wicce, which means witch. Witchcraft and magic are inextricable elements of the Wiccan way of life.
Though Wicca is often touted as a ‘mystery’ tradition (you can’t have it explained to you, you have to just do it to experience it), there is some need of initial education and training for prospective witches. This is probably for Health & Safety reasons – beginners shouldn’t be allowed to mess about with spells until they are fully aware of what they can do.
Witchcraftandmagic.uk is one source of training. It offers face-to-face courses ranging from introductory courses of various lengths and formats to hands-on Practical Magic Workshops ‘outdoors in woods’ and Paganism & Magic evening classes.
Practical Magic involves Pentacles, Wands and Abundance Magic as well as making certain Tools, whose nature and purpose will presumably become clear when you take the course. Other subjects covered include Shamanistic Masks & Tribal Rituals.
In the United States, the Church and School of Wicca offers a similar syllabus, though all online. This includes an Essential Witchcraft course taking budding witches though songs, prayers and incantations, initiation and fertility rituals, and much else in a Wiccan vein.
And a short online introduction to Wicca is IOA's Wicca for the Modern Age.
Whichever course you choose, you can leave the broomstick at home. You won’t be needing it. Things have moved on.
