Launceston Drysdale students were left without their teacher during class after the teacher had to leave unexpectedly.
It's believed the students were left after their teacher was unable to complete the class on Wednesday.
TasTAFE chief executive Jenny Dodd said a decision was made to ensure students were able to complete their learning experience after the incident.
"Ensuring students were able to complete their learning experience was the priority in the continuation of a Drysdale North commercial cookery class yesterday," she said.
"This was a one-off, unexpected circumstance. Students were made aware of the situation."
Ms Dodd said the students were supervised by a teacher in an adjacent classroom and a technical assistant who moved between the two classrooms as the students worked.
"When the teacher had to leave the class unexpectedly, a decision was made to continue the class so that students could complete the learning unit and would not have to repeat it at another time."
The incident will not have any impact on student learning, or the ability for TasTAFE to conduct its classes.
Teachers at TasTAFE have been in the spotlight recently after the CEPU raised concerns about a "teacher crisis" in the electrotechnology course.
Ms Dodd announced in March Tasmanian electrotechnology apprentices would have their training delayed until May, after the sudden departure of a teacher.
However, Ms Dodd hosed down claims of a crisis and confirmed only the one electrotechnology teacher had been left the organisation in the past 12 months.
