Overview

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.

The ESTAR/MSTAR universal screener and diagnostic assessment can be accessed at https://estarmstar.org.

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.

Professional Development

Professional development opportunities are currently available on the Texas Math Support Center site and offer CEU credits. 

The following are the course descriptions along with links to the courses. 

Universal Screeners Overview

This course provides a brief overview of the ESTAR/MSTAR universal screeners and describes how to interpret the results obtained after administering a screener. Results from the ESTAR/MSTAR universal screeners guide instructional decision making and help educators identify the intensity of support needed for students who might be at risk for not meeting expectations in algebra and algebra readiness skills. CEU credit is 2.

Diagnostic Assessments Overview

This course provides a brief overview of the ESTAR/MSTAR diagnostic assessments, examines how learning progressions fit with the diagnostic assessments, discusses how the diagnostic assessments were developed, and provides guidance on how to interpret the results. CEU credit is 2.

Learning Progressions

This course explores the learning progressions created specifically for the ESTAR/MSTAR diagnostic assessments. Participants will explore the definition of learning progressions in general, information about the ESTAR/MSTAR learning progressions, and the use of learning progressions in mathematics instruction and assessment in order to better prepare students for algebra. Participants will also become familiar with the ESTAR/MSTAR diagnostic assessments. CEU credit is 3.
