Another important function of STAAR is gauging how well schools and teachers prepare their students academically. STAAR helps to ensure that Texas students are competitive with other students both nationally and internationally. Every STAAR question is directly aligned to the TEKS currently in effect for the grade and subject or course being assessed. The State of Texas Assessments of Academic Readiness (STAAR ®) is a standardized academic achievement test designed to measure the extent to which a student has learned and is able to apply the defined knowledge and skills in the Texas Essential Knowledge and Skills (TEKS) at each tested grade, subject, and course.
