What Sirius Education Solutions does

Sirius Education Solutions is a Texas-focused K-12 educational publisher specializing in STAAR test preparation, operating as a subsidiary of MasteryPrep since a July 2025 merger. The company serves Texas public school districts and charters exclusively, covering all 20 STAAR-tested courses in Mathematics, Science, Reading Language Arts, and Social Studies from Grade 3 through End-of-Course. Its flagship product, Sirius Online, is a cloud-based digital learning platform that delivers TEKS-aligned instruction and authentic STAAR 2.0 practice with auto-scoring, diagnostics, and vertically integrated reporting from district to individual student. The platform includes the STAAR Summative Assessment Bank (14,000+ authentic items) and, as of July 2025, a new STAAR Formative Assessment Bank for classroom-level use, both of which integrate with district SIS and LMS systems via Clever, ClassLink, and EdLink.

The company operates a hybrid print and digital model. Sirius Online is sold as annual subscriptions packaged by grade band (Elementary 3-5, Middle School 6-8, High School EOC, or District Library for all 20 courses), while print workbooks (Preparation and Practice editions and Zingers) are sold as one-time consumables or bundled with online subscriptions at a discount. Pricing is quote-based and tiered by student license count. Distribution is enterprise-led through a direct field sales team targeting Texas school district administrators, with content marketing (case studies, free samplers, McREL-validated ESSA Tier IV research) supporting demand generation. The company is headquartered in Baton Rouge, Louisiana, employs 11-50 people, and earns ESSA Tier IV evidence-standard validation through a research partnership with McREL International. Recent product expansion targets SB 2124 advanced mathematics (Grades 6-7 for 2025-26, Grade 8 for 2026-27) and Spanish-language and ELPS resources for Emergent Bilingual students.

Expansion highlights5 records

Broad incumbents

• Edgenuity (Imagine Learning): Edgenuity provides online K-12 courses and credit recovery and competes with Sirius Online for Texas district digital supplemental-instruction and EOC prep contracts, especially in accelerated and credit-recovery use cases.
• IXL Learning: IXL provides standards-aligned K-12 practice and diagnostic content covering all 20 STAAR-tested subjects and competes directly for the same Texas district supplemental-instruction dollars Sirius pursues, with broader cross-curricular reach.
• Renaissance Learning: Renaissance offers Star Assessments and other K-12 assessment and analytics tools that compete with Sirius's STAAR Assessment Bank and reporting functionality. Both serve Texas districts with formative/summative assessment content integrated into district reporting workflows.
• Imagine Learning: Imagine Learning offers supplemental curriculum, assessment, and intervention solutions to K-12 districts, including Texas-specific content. It overlaps with Sirius on ELA/math STAAR prep and assessment analytics for Texas districts.
• MasteryPrep: MasteryPrep is now Sirius's parent company following the July 2025 merger and offers one-day ACT, SAT, STAAR, and TSIA2 boot camps across Texas. Pre-merger it was the closest direct peer, serving the same Texas districts with complementary assessment-prep delivery models.
• Curriculum Associates (iReady): Curriculum Associates provides iReady, a widely adopted K-12 diagnostic and instruction platform that competes for district supplemental-instruction budgets. Its Texas-aligned assessments and adaptive learning paths overlap with Sirius's TEKS-aligned instruction and STAAR prep positioning.
• Edmentum (Study Island/Exact Path): Edmentum offers Study Island and Exact Path, K-12 practice and adaptive learning products sold to Texas districts. Both Sirius and Edmentum compete for STAAR supplemental-instruction and accelerated-instruction budgets under HB 4545.

Regional players

• Lowman Consulting / Lead4Change: Lead4Change (formerly Lowman Education Foundation) offers Texas-specific staff development and TEKS-aligned resources to Texas districts, overlapping with Sirius's TEKS-aligned instructional content and serving the same Texas K-12 market.

Others

• Texas Education Agency (TEA) Resources: TEA publishes free released STAAR items, practice tests, and instructional resources that compete indirectly with Sirius's content. While not a commercial peer, TEA's free resources set a price floor and force commercial vendors like Sirius to differentiate on item volume, reporting, and instructional design.

Emerging players

• Summit K12: Summit K12 provides English Language Learner-focused STAAR preparation and TELPAS readiness for Texas districts, overlapping with Sirius's Emergent Bilingual and ELPS support offerings and competing in the same Texas ELL segment.
