Analysis of test-event counts in the norming sample by domain, term, grade, and school year (Table 2.1, Section 2.1), covering 2022/23 through 2024/25. The authors suggest the low grade 3 share may indicate most grade 3 students have progressed well beyond foundational reading skills.

"Across domains, grade 1 accounted for the largest share of test events (37.7%), followed by kindergarten (35.5%), grade 2 (20.9%), and grade 3 (5.9%). Together, kindergarten and grade 1 represented more than 70% of all test events."
