The officials said when Anna University applied for the IoE status at that time, no such norm was in place for half amount to be borne by state government.
The university plans to set up a Central Research Centre to focus on areas such as environment and water, the official said.
Interdisciplinary research centres are meant to bring researchers from different disciplines together under one roof to work collectively on the various aspects of a research project.
State government’s confirmation and commitment is awaited in the case of four other institutions.
The decision was taken following a recommendation made by the University Grants Commission last month on the basis of the advice of an Empowered Expert Committee.
