TEKS TOOLS [Grade 6]
Since the 2022 STAAR redesign, aka STAAR 2.0, a noted increase in complexity has emerged. Students are asked to think and solve in ways that even cause some adults to pause. Rather than more drill and test prep, a more nuanced approach is needed to ensure student success. Each year's test brings new surprises, and it's necessary for us to equip them with better tools to make sense of the problems. Process standards Instead of prepping them based on what the test looked like l

Lessons learned from the 2025 6th Grade Math STAAR
Using a modified version of the statewide item analysis report, I examined the readiness standards that had less than 60% mastery. Each standard has both an analysis of the items themselves to infer what made them so difficult and instructional implications for educators to ensure a more successful 2026 STAAR test. Standard # of items % mastery 6.8D 1 25 6.7D 1 28 6.5B 1 31 6.8A 1 41 6.12D 1 42 6.10A 1 46 6.3E 2 49.5 6.2D 2 50.5 6.12C 2 51.5 6.4B 2 51.5 6.13A 1 55 6.3D 2 55
