A UNION has asked that a panel investigating troubled De La Salle College be scrapped and set up again with different people.
The University and College Union (UCU) said it was dismayed at the appointment of two of the three member panel.
Education minister John O'Dowd last week selected former Nipsa general secretary John Corey, Belfast Metropolitan College (BMC) chief executive Marie-Thérèse McGivern and Sir Robert Salisbury, a former professor in the School of Education at the University of Nottingham.
The investigation will look at issues including staff welfare and work relationships, the role of senior leadership and management and the impact on teaching and learning and pupils' attainment.
The west Belfast school has been in turmoil over a breakdown in relations between some of the 70-strong staff and the principal Claire White for several months.
Two associate principals have been appointed to the school.
In a letter to the Department of Education, the UCU said it objected to the appointment of Ms McGivern and Sir Robert due to the union "having experience of these personnel within an industrial relations context in the further education sector".
Late last month an industrial tribunal ruled that a former BMC employee had been "constructively and unfairly dismissed" by the college. As principal and chief executive, Ms McGivern was among those called to give evidence.
The UCU letter to Mr O'Dowd said it was "staggering" that Ms McGivern had been selected "only weeks after the Met was found by an industrial tribunal to have unfairly constructively dismissed a UCU member".
The union also said it was concerned at Sir Robert's inclusion. He conducted a review of industrial relations in further education in 2013, with which the UCU had issues.
"The UCU respectfully urges the minister and the department to reconsider the composition of the De La Salle taskforce," the union said.
Mr O'Dowd said his announcement of an independent investigation into the situation at De La Salle had been welcomed widely.
"While I accept that people outside the school may have their own views of those appointed to the panel, the UCU have no direct involvement within De La Salle and in that context the school needs space during this crucial time to get on with their examinations with the least possible distractions and I urge everyone to respect this," he said.
"I have previously stated that I consider the panel members to be well qualified and experienced to investigate the circumstances in the school and to make recommendations to ensure the school’s future going forward. This remains my view.
"My priority continues to be for the pupils at the school and this investigation will give the pupils, parents, staff and their representatives and all those involved with the governance of the school the opportunity to express their views."
