Figure 1. Structural model of the relationship between variables ( Sugiyono, 2017).

Description:

ξ_1 = latent variable effectiveness of leadership behavior patterns

η1 = latent variable of teacher performance

η2 = latent variable of student achievement

γ_12 = coefficient of direct influence of variable effectiveness of leadership behavior patterns on student achievement.

γ_11 = coefficient of direct influence of variable effectiveness of leadership behavior patterns on teacher performance.

β_12 = coefficient of influence of teacher performance variables on student achievement variables

ζ_1 = Measurement error effectiveness of leadership behavior patterns

ζ_2 = Measurement error of teacher performance

ζ_3 = Measurement error of student achievement.
