Objective.

To validate a scale through the Theory of Response to the Item that provides information about the violent behaviors that teachers use against students according to the perception of those identifying the type of violence.

Method.

1536 students from 14 secondary schools in vulnerable areas in seven localities of the State of Sonora, the three grades from this level participated. The Scale of Teaching Violence, a Likert type scale, was used to measure aggression type and the General Violence Indicator (IGV) to get an overview of violence.

Results.

The model of Item Response Theory and confirmatory factor analysis (CFA) was performed to obtain information about the perception that secondary school students have about the different types of teacher violence. Four dimensions were obtained (physical violence, humiliation, sexual and mockery) with Cronbach's alpha of 0.87, 0.82, 0.85 and 0.85, respectively, total explained variance of 46.42 % and goodness-of-fit indexes of CMIN / DF: 3.08, CFI: 0.92, RMSEA: 0.05, SRMR: 0.04, GFI: 0.89 and AIC: 1369.

Conclusion.

The teacher violence scale resulted in a four-dimensional model, valid and reliable, for pre-adolescent secondary school students, from areas at risk of intrafamiliar violence.
