This study aims to evaluate the psychometrics characteristics of the Escala de Desempenho em Informática Educacional (EDIE). The subjects were 344 public (57,8%) and private (42,2%) basic schoolteachers (85,5%) with 20 to 67 years (M=38,9; DP=8,1). 79,4% was female. EDIE, which had 51 Likert items with four answer choices each, was answered individually. The scale objective was to define teachers’ performance. The results showed a good internal consistency (aCronbach =0,97). The internal reliability, verified by the split-half method, was 0,84 and it showed that the items were homogenous. The factor analysis found the performance factor (21 items) and management factor (19 items). So 11 items were eliminated items and the latest EDIE version retained 40 items.

Palabras clave : Educational evaluation; Test construct; Psychometrics; Likert scale; Educational informatics.
