A school resource deputy was asked to assist the principal. The deputy said he could tell Jardine was extremely intoxicated.
Initially, Jardine denied drinking any alcohol but later admitted she drank on Tuesday night, Wednesday morning before school and during lunch in her classroom.
Jardine blew a .205 breath alcohol concentration, according to the Pinal County Sheriff's Office.
She told the deputy that she took a taxi cab to school because she was afraid that she was too drunk to drive.
