Looking for reasons to approach public charter schools with your products, and ways to tackle it? EdWeek Market Brief examines this emerging market.

Projected to grow at least 20 percent over the next 20 years, the charter school market can be confounding for companies that sell everything from ed-tech to furniture. Charters can be challenging for cash flow, too, since their per-pupil funding levels are often lower than in traditional public schools, and new charters might not be able to make payment until they welcome their first students.
