Victorians will have to wait a little longer to see the contents of a report into the state's youth justice centres.

The final report is expected to be tabled in state parliament on March 6.

Already subject to a six-month delay and two further extensions, the report was expected on Tuesday, but has to wait for parliament to return before being made public.

The previous timeline extensions have been partly due to difficulties getting evidence from the justice and health departments.

In one instance, records given to the Legal and Social Issues Committee by the Department of Health and Human Services were "extremely difficult" to analyse and later revealed to be partially inaccurate.

A public hearing in 2017 was presented with allegations a former teacher at a youth prison school was pressured to give misleading evidence in court.

Brendan Murray, who used to run Parkville College, accused education department staff of telling him what he should say about housing youth offenders in an adult jail.

In an interim report released in December, the committee said it wasn't resourced to investigate the allegation and referred it to the Victorian Ombudsman.
