A Department of Education strategy to grow integrated education has been called "an action plan with no action".
The criticism came from an organisation representing former pupils from integrated schools.
The department has a new legal obligation to give more support to integrated education.
That has been the case since Stormont voted in favour of a new law in one of their last acts before the assembly was dissolved in March 2022.
It was based on bill brought by Alliance Party assembly member Kellie Armstrong.
The law means the department has to grow the number of integrated school places and the number of children being educated in them.
The department said it was committed to meeting its statutory duties under the education act.
