Since the formal intervention process was introduced six years ago, almost 50 schools across the north have been involved, with five shutting down.
St John the Baptist PS is just the second school to enter the process this year following St Mary's PS in Killyleagh.
Schools are typically placed into formal intervention if inspectors rate the quality of education as unsatisfactory or inadequate.
Through the process, schools receive tailored support from the north's Education Authority, assisted where appropriate by the relevant sectoral body.
The school must commit to working to deliver an agreed action plan to address the areas for improvement identified in the inspection report.
At present there are 11 schools involved including Fleming Fulton Special School in Belfast, Tullygally PS in Lurgan, Movilla High in Newtownards and Dundonald High, which is the only one to have entered the process twice.
Almost four times as many state as Catholic schools have been placed under special measures.
Only seven of the 49 schools told to make drastic improvements since the formal intervention process was introduced in 2009 have been Catholic managed compared to 26 from the state controlled sector.
Crumlin Integrated College spent the longest continuous period in intervention - almost four and a half years. It is out now but a proposal to shut it down has been published.
Ballee Community High in Ballymena, Orangefield and St Gemma's Highs in Belfast, Dunmurry High and Beechfield PS in Belfast all shut down before existing the process.
