Reuters reports that 57-year-old Kathleen Jardine, a math teacher at Poston Butte High School in San Tan Valley, arrived to school under the influence of alcohol. Jardine admitted to authorities that she had been drinking the night before class, as well as the morning of class and during the school day.

Jardine took a cab to school because she felt she was too intoxicated to drive. Her car had been impounded the night before, when she was cited for driving under the influence.

A school security guard found a half-empty bottle of vodka, a bottle of Sunny D citrus beverage and an empty single-serving bottle of wine in her classroom.

Jardine’s blood alcohol level was .205, according to police. In Arizona .08 is the legal limit for driving purposes.

Of course, teachers are held to an even higher standard.

Police charged Jardine with one count of public consumption of alcohol. She could also face disorderly conduct charges. The school has not released information yet on how Jardine will be disciplined.

The teacher faced a similar charge in New Mexico, where she was reportedly fired in 2011 for being drunk in the classroom.

It's already proving to be a rough start to the school year for teachers. An Oklahoma teacher was found intoxicated and without pants in an empty classroom earlier this month.
