High school students may be forced to study for an extra year, if a worst-case coronavirus scenario plays out.

The news would be a nightmare scenario for many year 12 students, with schools facing the prospect of delivering an unprecedented “Year 13” for students.

Many students around the country will move to an online-only learning environment after the Easter holidays.

However, Prime Minister Scott Morrison has resisted calls to enforce a nationwide move to online-only learning, fearing the impact of prolonged school shutdowns on students’ educations.

The introduction of a one-off Year 13 is part of a worst-case scenario, with some states already categorically ruling out holding students back and others weighing up the option of a partial repeated year for affected students.

Education Minister Dan Tehan has said that getting Year 12 students to graduate has now become a top priority for the states and territories.
