FLORENCE, Ariz. – An Arizona high school teacher who was allegedly busted in class with a blood-alcohol level more than double the legal limit to drive could lose her job for the second time since 2011.

Poston Butte High School teacher Kathleen Jardine, 57, allegedly registered a .205 blood-alcohol level when a deputy responded to complaints from students that the teacher was drunk and yelling at students, SanTanValley.com reports.

“When the deputy spoke with Jardine, he could tell she was extremely intoxicated. Initially, Jardine denied drinking any alcohol but later admitted she drank the night prior, that morning before school and during lunch in her classroom,” the news site reports.

“The deputy asked Jardine how she got to school today and she said, ‘I was afraid I was too intoxicated to drive so I took a cab this morning.’”

Her drink of choice, apparently, is Sunny D and vodka, with a white wine chaser. When a school security officer went to fetch her purse from class, he reportedly discovered “a half full 750 ml bottle of Fleischmann’s Vodka, an empty single serving size bottle of Beringer white wine and a half full bottle of Sunny D,” according to SanTanValley.com.

“ Jardine confirmed the alcohol belonged to her.”

The incident also wasn’t Jardine’s first.

Sheriff Paul Babeu issued a harshly worded statement about the incident at Poston Butte and Jardine’s history of alcohol problems.

“Learning math can be hard enough, I can’t imagine trying to learn it from a drunk teacher,” the sheriff said, according to the news site. “This is not the first time teacher Kathleen Jardine was been intoxicated in the classroom.

“During September of 2011 she was a math teacher at Belen High School in New Mexico. Students reported to their administration she was ‘acting strange and slurring her words.’ It was determined she was intoxicated and she was later fired from the school,” he said.

In the most recent incident Jardine was charged with public intoxication, but after interviews with students who said she was yelling and cursing in class, she now also faces a possible disorderly conduct charge, SunTanValley.com reports.

The teacher was eventually released to the custody of her daughter.

Jardine certainly isn’t the first teacher to come to class drunk, but her history of alcohol abuse should raise concerns from parents about the district’s hiring practices. Things happen, often times without warning, but that’s clearly not the case with Jardine.

If school officials knew of her past problems, why would they put her in a position to repeat her bad behavior? And if they weren’t aware, why didn’t they do a more thorough background check?

The whole episode is undoubtedly an embarrassing for the school district, but it seems to have been entirely preventable.
