MasteryPrep Acquires Sirius Education to Strengthen STAAR and TSIA2 Prep for Texas Schools

Founded in 2009, Sirius brings a trusted STAAR brand and deep Texas footprint to MasteryPrep’s growing K–12 portfolio

  • July 7, 2025

Baton Rouge, LA — MasteryPrep, the leading provider of TSIA2 and college readiness test prep solutions in Texas and nationwide, today announced its acquisition of Sirius Education Solutions, a trusted provider of STAAR preparation materials for Texas schools.

“Sirius was founded on the belief that high-quality, accessible instructional materials can make a difference in every classroom,” said Andrew Roberts, CEO of Sirius Education Solutions. “By joining MasteryPrep, we’re accelerating that mission, giving our schools even more tools to support students on their full educational journey.”

Founded in 2009, Sirius is a longtime partner to Texas educators, offering both digital and print solutions that support measurable gains on STAAR assessments. The company provides resources for all 20 STAAR-tested subjects—including six Spanish-language assessments—supporting Grades 3-12 through end-of-grade (EOG) and end-of-course (EOC) exam preparation.

This combination brings together two mission-driven organizations committed to improving outcomes for students across the state, creating the only comprehensive, Texas-specific pipeline from STAAR achievement to college and career readiness.

“Texas educators are under growing pressure to meet high-stakes accountability goals while ensuring students are prepared for life after high school,” said Craig Gehring, Founder and CEO of MasteryPrep. “By combining our strengths, we’re delivering an end-to-end academic support system built for Texas schools—from grade-level mastery to postsecondary success.”

Together, Sirius Education and MasteryPrep will continue delivering the standards-aligned print and digital materials that Texas educators have relied on since 2009—now with the added benefit of MasteryPrep’s scale, enabling faster content updates, deeper data insights, and expanded customer support.

The partnership significantly expands MasteryPrep’s presence in Texas and enhances its offerings in EOC and EOG preparation—critical components of the company’s broader mission to serve students across the full academic spectrum.

Earlier this year, MasteryPrep also became the official strategic partner of ACT Education Corp., powering its new in-classroom test preparation platform. With the addition of Sirius, MasteryPrep extends its reach and impact in both state-specific and national assessment ecosystems.
