Sirius Education Solutions is a Texas-based company of former educators who know how important STAAR test results are to students, teachers, schools, and districts. We publish test prep programs, both in print and online, for the End Of Course, Middle School, and Grades 3-5 STAAR exams. Our programs are different because they were developed using multiple released STAAR tests; they blend TEKS instruction with authentic STAAR practice; they have a 3-step approach to prioritize and individualize remediation; and they can be used in varied settings and contexts. Our staff includes teachers and professional content and test-item writing experts who have managed and written high-stakes tests. At Sirius, we take enormous pride in creating innovative and effective test preparation solutions designed to provide enduring success for Texas educators and students.
