Note: GPA = grade point average.

Other rotations tested, but no education coefficients were significant (p < .05).

Unadjusted model fit: comparative fit index (CFI) = .990, root mean square error of approximation (RMSEA) = .027. Adjusted model fit: CFI = .938, RMSEA = .033.

Unadjusted model fit: CFI = .965, RMSEA = .041. Adjusted model fit: CFI = .963, RMSEA = .025.

Unadjusted model fit: CFI = .996, RMSEA = .018. Adjusted model fit: CFI = .962, RMSEA = .031.
