Teachers Pay Teacher is an online marketplace where educators can market their original content, ranging from lesson plans and workbooks to classroom decorations and clip art. Products can be shipped or downloadable. But must be original and not subject to another author’s copyright. Content also may not trivialize traumatic events (slavery, Holocaust, etc.); discriminate; or include pornography. The items, after all, are aimed at public- and private-school kids, grades pre-K to 12.

Sellers set the price of their product and can offer promotions or freebies, if they chose. However, to list products for sale on the site, you must become a member. There are two membership options. One has no upfront fee, but charges a 45% commission, plus 30 cents per item, on everything the educator sells. The other option requires a $60 annual fee, but drops the commission rate to 20%. With the paid-subscription model, the teacher is only charged per-item fees for products sold for less than $3.
