Micro-data Sample G02 2018-19 Mathematics
In the section it is possible, after registering on the site, to download micro-data (in SPSS format) related to the sample surveys. In each national survey, INVALSI selects a two-stage probability sample, stratified at the first stage, in which the first-stage units are school sites (the institutes) and the second-stage units are the sections. In the Sample Survey, the tests are conducted under the supervision of observers outside the classroom and school faculty.
