CogCom3 = perceived cognitive competence time3; T-rated Engage = Teacher-rated effortful engagement; T-rated Achieve = Teacher-rated academic achievement. All coefficients are average coefficients across the 10 imputed datasets.

Because step 2 is the same for each outcome model, it is not repeated for each model.

In step 3 the outcome variable is the Year 3 variable controlling for the Year 2 score.
