Claims¶
- In Grade 9, negative achievement trends emerged for non-SEN and SEN-L-R students in all domains, and SEN-L-R trends were always significantly more pronounced than for non-SEN peers [+W]
- Grade 4 cohorts affected by COVID-19 restrictions showed significant negative trends in verbal achievement for non-SEN and SEN-L-R students in all three domains, and for SEN-L-S students only in orthography [+W]
- During the pandemic, Grade 4 students with SEN-L experienced less favorable home learning environments and lower parental support than non-SEN students, while Grade 9 group differences were largely non-significant [+W]
- In Grade 9, fewer problems during distance learning were associated with better verbal achievement, summer school attendance was associated with lower reading and listening achievement, and learning-condition relations did not differ between student groups [+W]
