Google's getting serious about education. Its Play for Education portal, announced last month at I/O, is creeping ever closer to a full launch, with a call for application submissions starting today. Developers that want to be considered for Google's curated storefront can mark their applications for consideration now via the Play Developer Console. But unlike the wild, wild west of the Play store at-large, where anything goes, not every education-focused app will get the greenlight. In fact, Google's submission process requires all applications marked as suitable for K-12 to first pass through a network of non-affiliated educators for evaluation before then being measured against the Play for Education store's requirements for classroom use. If selected, developer's applications will be made available to the many pilot programs currently underway across the country, with an eventual full-scale rollout when Play for Education officially launches sometime this fall.
