TASMANIAN law students have allegedly cheated in an online exam, so the entire class will be retested.
A University of Tasmania spokesman said some law students had improperly shared information.
A university statement said law faculty staff believed the integrity of an online assessment was compromised by some students collaborating in a way that was inappropriate.
In response, unit co-ordinators replaced that assessment with a new assessment, comprising in-class tests and an end-of-semester formal exam.
"The university takes academic misconduct very seriously, and we have a number of processes in place to monitor and discourage such activity," deputy vice-chancellor (students and education) Professor David Sadler said.
"We would urge students not to resort to practices which risk jeopardising their studies.
"We provide students with access to a range of specialised support, resources and training opportunities to help them understand all forms of academic misconduct.
"Identified students found to have been involved in sharing information about the online assessment will be counselled in line with the university's high academic standards."
It is understood the students were studying a unit called criminal procedures, and 162 students will be retested.
Senior law figures have warned that academic misconduct was viewed seriously, and it would be considered by the Supreme Court when deciding if a person was "fit and proper" to practise law.
