Maybe worth pointing this out for context: the state's press release about the 2022 data:

> In mathematics, students saw gains in nearly all grades as compared to the prior year’s assessment administered in Early Fall 2021. However, student outcomes have not returned to pre-pandemic levels. In middle school, 17.6% of sixth grade students were proficient in math and just 6.5% of students who took the grade 8 assessment were proficient. The percent of students proficient in Algebra I was 14.5%, below pre-pandemic results of 27% proficient in 2019.

But also, to echo myself, if anybody wants to take Sinclair's numbers seriously, they should be expected to explain why 2000 students from 23 schools is in any way representative of those schools' entire student bodies.
