q2 · i? · associational · r1

District-aggregated 2016 survey analysis rank-ordered into quartiles by teacher agreement on seven SLO support items (Figure IV-1). The report calls the 20 percentage point difference evidence that some districts prepare educators better than others.

"In the top quartile of districts with stronger SLO implementation, 62% of teachers agree that they receive at least five SLO support strategies. At the other extreme, in districts with weaker SLO implementation, only 42% of teachers agree"
