q3 · i? · associational · r3

Autocorrelation analysis of teacher grade effects across years in the CPS sample (Table 3). Lag-1 total effect correlations range from 0.598 (English) to 0.669 (science); persistent effects range 0.444-0.625 and mismatch 0.478-0.583, showing "grade effects tend to be stable over time."

"Ninth-grade teachers' grade effects tend to be stable over time, with auto-correlations across years that are similar or higher than those reported for value-added based on test scores, which tend to range from 0.18 to 0.64"
