Micro-data Sample G02 2020-21 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.

Micro-data Population Municipal G02 2020-21 Mathematics
In questa sezione i ricercatori appartenenti ad Enti riconosciuti possono richiedere matrici di dati in cui appare anche il Comune in cui la scuola è dislocata. Queste matrici sono ridotte rispetto alle matrici di Popolazione sia in termini di casi che in termini di variabili rilasciate.
In termini di casi, poiché includono solo gli studenti in comuni con almeno 3 istituti scolastici per grado scolastico.
In termini di variabili, poiché il set di informazioni di contesto relative agli studenti è ridotto a: origine, regolarità degli studi, titolo studio dei genitori, indice di status socio-economico e culturale (ESCS).
