The test is whether the education relates to your current business. Courses, workshops, certifications, books, and industry conferences that keep your skills current or sharpen them for the work you already do are deductible business expenses.
Education that trains you for a new trade or profession, or that meets the minimum requirement to enter your field in the first place, is not deductible as a business expense, even if it is useful. Different personal education tax credits may apply in some cases, but those are separate from the business deduction.
Related travel to attend qualifying training can also be deductible under the travel rules. Keep receipts and a note of how the education relates to your current business.
The line between improving your current skills and training for a new career can be blurry. A photographer taking an advanced lighting workshop is clearly improving current skills; a photographer studying to become an accountant is not. When it is genuinely a gray area, it is worth a quick check with a tax professional before you claim it.
