Liberty Source LLC has provided assessment solutions and services to school districts throughout the United States since 1996. We strive to provide leading-edge solutions to meet the unique needs of school districts to help students maximize their potential.


In July of 2023, Liberty Source was acquired by Harris Educational Solutions, a business unit of Harris Computer Corporation.  Harris Executive Vice President Daniel Youngren said, “The Liberty Source Tango platform, diagnostic screeners and remediation tools, in both English and Spanish, add critical content to our suite of assessment solutions.  The team behind Tango are experts in crafting standards aligned assessments and other tools that make identifying and remediating student learning gaps an efficient and powerful process for teachers and administrators.  Tango makes it very easy to monitor and guide student progress toward mastery.  We are very excited to have them joining our K-12 team and leveraging Tango’s diagnostic and remediation tools in combination with our other assessment and data analysis platforms.”


Liberty Source’s product lines will join the portfolio of Harris Education Solutions, which provides student and educator growth solutions through a broad range of assessment, curriculum, RTI/MTSS, analytics, evaluation/observation and student data management systems.
