The different margins of error in the sample assessment, for example, make it difficult for a detailed analysis of the performance of each locality and prevent comparison between federative units.
In Bahia, for example, microdados consider a sampling of 515 students, distributed in 20 schools, and indicate a rate of 40.3% literacy. However, this number is subject to a variation of 21.5 percentage points.
In Tocantins, a rate of 24.3% of literate students was verified, considering a sample of 727 students distributed in 27 schools. The margin of error is 4.5 percentage points.
Despite the limitations in state accuracy, Inep states that there was a “tendency to increase in literacy level detected by the literate child indicator”.
DATA DISCLOSURE DISCLOSURE

“We haven’t published yet [os dados do Saeb de 2023] using performance standards as a reference because a national concertation lacks minimum”he said.
According to Palacios, a standard of literacy in the country will be presented to all Brazilian states, defined by a survey by Inep in 2023, so that the data is calculated based on this parameter.
“This research led us to fix what is the national standard of literacy, which at the time was associated with the 743 points on the literacy scale“, These.
