The expertise audit

You already have valuable curriculum.
Most of it isn't packaged yet.

The gap between ‘I teach this well’ and ‘I have a sellable curriculum product’ is smaller than most teachers think — and almost entirely about packaging rather than creation. You've already done the hardest part: you've worked out how to explain something complex, which examples unlock understanding, which misconceptions need addressing early, and which activities produce the outcomes you're after. The curriculum exists. It just isn't formatted as a sellable product.

Identify your strongest content areas

What do colleagues
already ask you for?

The fastest signal of market value is what your colleagues already ask you for. If other teachers in your department regularly borrow your Year 11 organic chemistry revision materials or your A-Level essay scaffold — these are candidates for your first listing. Existing demand from colleagues is the closest proxy for marketplace demand.

💡Your pedagogical distinctiveness is your competitive advantage
Your distinctive angle is not just content coverage — it's the approach. Your Year 10 Chemistry unit might be distinctive because it frontloads misconception-tackling, rather than leaving misconceptions to appear as errors in practice questions. This approach is not in a textbook. It's yours. It's the reason schools will adopt your listing over others on the same topic.
Check what is already well-served

Don't compete with
established resources.

Before investing time in packaging a topic, search the marketplace for existing listings. If there are 20 well-reviewed resources for GCSE trigonometry, your resource will need a distinctive angle to convert. If there are 2 resources for A-Level Further Mathematics complex numbers and both have minimal reviews, you have an underserved niche with clear demand.

The minimum viable curriculum product

Not a full course.
A complete, publishable unit.

Your first listing does not need to be a full course. The minimum viable curriculum product is a complete unit plan (4–6 lessons) with: a clear scope statement, learning objectives written as student abilities, teacher notes that a teacher who has never met you can follow, student-facing materials, and a formative assessment. This is publishable, adoptable, and demonstrates your quality to future buyers.
