A Sunshine Coast principal charged for drink driving at more than four times the legal limit has described her behaviour as a ''poor decision'' on her school's social media page.

Jacqueline Patricia King, 55, leads the independent Chancellor State College on the Sunshine Coast, a school with almost 3,000 students from Prep to Year 12.

Overnight she published a statement, saying that principals like her needed to be "beacons of leadership and guidance" to parents and act as role models both inside and outside the school.

"I am not proud of my appearance before court today on a high range drink driving charge," she said.

"I made a poor decision that could have carried far more serious consequences, and for that I apologise unreservedly."

Ms King pleaded guilty in Maroochydore Magistrates Court on Monday to driving under the influence of liquor, the most serious drink driving charge in Queensland.

The executive principal was pulled over on January 14 on Tanawha Tourist Drive in Tanawha, less than five minutes' drive from the campus grounds.

Police recorded an alcohol reading of 0.23, or more than four times the legal limit.

In court documents viewed by ABC Sunshine Coast, a Department of Education director endorsed Ms King as an educator, despite her criminal behaviour.

Ms King said she accepted the court's punishment and would "make a commitment to learn from this and to be a better person because of it".

North Coast regional director Liam Smith described Ms King as hardworking, industrious and highly regarded.

"She is a highly effective executive principal who has a strong moral compass of the children in her care," Dr Smith wrote.

"As principal, she models the behaviours expected of others, setting high standards for the achievement of outcomes for herself, her students, staff and parents."

Dr Smith added there were "no code of conduct breaches" against Ms King and said the behaviour that brought her to court was "inconsistent and out of character with her usual conduct".
