PIE is an Open Source Framework. Any content (or new question types) you create belong to you. You do not require a licence, payment or partnership with any organization to use or share your content.
PIE provides an open non-proprietary format for Assement Content that preserves the design and functionality that the content developer intended. Both for simpler question types and more advanced interactions.
You can Integrate question authoring to your site using any PIE-compatible question types.
The PIE Framework is not itself a standard, but a working set of software tools. It can work within and support a number of existing education technology standards.
You can create new and innovative interactions to deliver a more engaging and effective assessment experience. Or create or modify existing question types so they perfectly represent your educational and design standards.
