This new section of the Android app store sells apps aimed at schools and teachers.
From the Appnewser article:
Google Play will let teachers and schools buy multiple copies of an app in bulk. When a teacher buys an app it will automatically download on their own device, as well as onto the devices of all of their students. In addition, schools can make credit cards available to teachers, so that a teacher doesn’t have to use their personal credit card to buy an app for students.
Google will begin accepting K-12 app submissions for this educational category this summer. Follow this link to get details on how to submit your app for this category.
