More than 225,000 students in Victorian primary schools are learning a language, up from 200,000 since last year.

In the past two years there has been a 30 per cent increase in students taking on a language, according to figures from the Education Department.

Asian languages are leading the charge, with a 20 per cent rise in students taking on an Asian language in the last year.

Mandarin is up by 34.4 per cent, Indonesian up by 13.7 per cent and Japanese 9 per cent.

While Italian is still the most widely taught language in the state, its enrolment numbers are down by almost 1 per cent.

The number of students studying a language is set to skyrocket from next year when all prep students begin compulsory language education.

The initiative will see students learn a language other than English until year 10, and will have certain benchmarks to meet to get a proficiency certificate.

All preps starting next year will be given a passport-style book to track their progress until grade three, with teachers stamping their milestones.

Passports will be available in the eight most widely taught languages – Italian, Indonesian, French, Chinese, Japanese, German, Spanish and Greek.

Greek has been seeing a slight rise in primary school student numbers, with 2,579 students enrolled in 2013, up from 2103 in 2012.

Greek is taught in only 1.6 per cent of Victorian schools despite there being 252,217 people with Greek heritage living in Victoria.

Thirteen primary schools and eight high schools offer the language.

A total of 4,355 students in government primary and secondary schools were taught Greek as a second language.

Three-quarters of government primary schools were already offering languages in 2014, with many more expected to start programs for the first time next year.
