The Elementary School Students in Texas Algebra Ready (ESTAR) and the Middle School Students in Texas Algebra Ready (MSTAR) online assessments were created to help drive instructional decisions about students' algebra readiness and support district and campus Multi-Tiered Systems of Support (MTSS).
The ESTAR (grades 2–4) and MSTAR (grades 5–8) universal screeners consist of approximately 24 questions that assess understanding in positive whole and rational numbers along with understanding of variables, expressions, and equations. The results of the screener inform educators on which students may be at risk for not meeting algebra readiness expectations and the degree of support students may need. The universal screener can be administered three times a year for progress monitoring.
Following the administration of the ESTAR/MSTAR universal screener, select students should be given a more focused and comprehensive ESTAR/MSTAR diagnostic assessment so that the teacher can determine specific intervention needs.
Additional tools within the system provide decision-making support for campus and district MTSS teams. Connected lessons for intervention are also available.
Districts that would like to administer the ESTAR/MSTAR universal screener and diagnostic assessments must create unique district administrator accounts as well as teacher and student accounts. For questions about accounts and general assistance related to the ESTAR/MSTAR universal screener or diagnostic assessments set-up, please contact mathtx@esc13.net.
