The Queensland Opposition has seized on new documents surrounding the selection of an executive principal for the much touted Inner City South State Secondary College, accusing Deputy Premier Jackie Trad of meddling in the process.

Key points: The report contradicts the reason given by the Department of Education for the re-advertisement of the role last year

But the Deputy Premier maintains she didn't interfere with the selection process She is also accused of being in direct contact with a senior education department bureaucrat during the recruitment

Principal Kirsten Ferdinands was last year appointed to lead the school, which is currently under construction on Brisbane's south side, despite a panel selecting candidate Tracey Cook weeks earlier.

While the selection panel originally signed off on Ms Cook's appointment, the position was re-advertised in May at a more senior level based on new modelling that the school would likely outgrow its projected size, according to the Department of Education.

The selection process drew political attention late last year when Ms Trad admitted she spoke with both candidates during the recruitment period but denied interfering.

At the time, Education director-general Tony Cook backed up the Deputy Premier's statement, saying the department initiated those meetings and re-advertised the position after it received "new demographic modelling [that] indicated the school would exceed 1,600 students".

Documents tabled to parliament revealed the report containing the new demographic modelling was received by the department in January — the same month the original position was first advertised.

Opposition education spokesman Jarrod Bleijie tabled the report to Parliament on Tuesday saying the timeline did not add up.

"They are using that as an excuse to reclassify the role after the successful candidate had a meeting with the Deputy Premier," he said to Parliament.

Mr Bleijie also accused Ms Trad of being in direct contact with a senior education department bureaucrat during the recruitment process, using Parliamentary privilege to level the claims.

"If it is, the allegations, that a member of Parliament text messaged deputy director-general of departments about selection processes, then that seriously does undermine the independent selection process across the state," he said.

"I will be writing to the Crime and Corruption Commission (CCC) for a third time on this matter now."

It is the latest political attack to come from the Opposition following last year's pursuit of Ms Trad over her failure to properly declare her investment house purchase.

Ms Trad has repeatedly denied interfering in the selection process of principals, denying Mr Bleijie's claims.

"I take personal offence at that inference," she said in Parliament.

"It is not a fact. You are inferring."

A spokesman for Ms Trad told the ABC "the Deputy Premier did not interfere with the selection process", saying as the matter was with the CCC, "it would be inappropriate to comment further".
