I think it would be as simple as asking questions about whether apprentices are having issues finding an apprenticeship or getting experience. You also have to ask the businesses that you are attracting to pay if they have problems finding apprentices. Make sure you do ample research on what already exists out there because this could speed up your market fit by essentially copying what others have built, and building on what is wrong with the platforms.
