NOTE: Development on a new site for SmarterApp content is underway! With the new site, we will begin transitioning SmarterApp resources into an easier-to-use, accessible interface.

Only SmarterApp content updated in 2020 and after should be considered current and accurate. If you plan to use, are looking for specific information, or have any questions about content on this site, please contact us at support@smarterbalanced.org.

Smarter Balanced is pleased to release a report on the performance of the May 2016 release of the open source Test Delivery System (TDS). This release increases capacity from 20,000 to 50,000 concurrent students, is faster and more responsive, and deployment and configuration have been dramatically improved.

As of Fall 2018 the Smarter Balanced Test Delivery System (TDS) is no longer supported.

The code base and documentation for the TDS is available within the Smarter Balanced GitHub repository.
