Labor is entering the final week of the NSW campaign trail lambasting the government for underfunding public schools and pledging a $100 rebate for parents whose children want to learn languages.

New figures from the Department of Education show the number of demountables used as classrooms spiked to 5093 in April last year, the NSW Teachers Federation said on Saturday.
