Meloni told a youth rally in Rome that a new cabinet bill will soon set a maximum number of foreign students per classroom and outlaw face coverings in schools.
The proposal also obliges parents of foreign pupils who struggle to integrate to learn Italian, and it bans burqas and niqabs inside school premises.
She warned that a single non‑Italian‑speaking child can be helped by classmates, but a majority would signal neglect, according to her.
Italy, lying in the central Mediterranean, is one of Europe's most exposed migration corridors, a fact that has made immigration a persistent flashpoint for successive governments.
National statistics show that foreign‑national students account for 11.6% of enrollment, roughly 12 out of every 100 pupils, according to the Fondazione ISMU.
The cabinet is expected to debate the bill later this week, setting the threshold that could alter classroom demographics across the country.
