The third-party reference report is the final instrument to be completed between weeks 14 and 17 from the delivery of the materials. Teachers receive the Individual Evaluation Report about 8 months after the start of the process. As shown in Table 2.7, by 2010, 69 643 municipal teachers had participated in the teacher performance evaluation system, of whom 13 792 were evaluated at least a second time. Taking into account the number of teachers in municipal schools in 2010 (about 81 000) and the proportion of teachers who had been evaluated who were still teaching in a municipal school in 2010 (about 88%), it can be concluded that about a quarter of the 2010 municipal teaching working force had not undergone an evaluation process.
