This document discusses TAO APIs for integrating standalone items into computer-based assessment platforms. It provides an overview of the available APIs, including client-side and server-side APIs, and how they can be used for item I/O, backend setup, event logging, item state, and more. It also describes how to run a standalone item and which features are needed to integrate it with a CBA platform using the Item Runtime and Workflow Runtime APIs. The document encourages contributions to the TAO APIs by discussing support resources on the TAO Forge.
