Students and staff are now able to access rapid coronavirus testing through their local college.
More than 100,000 lateral flow testing kits have been distributed to colleges across Scotland to help detect cases in people with no symptoms.
Authorities are urging people to take part in voluntary testing twice a week using the at-home kits.
A limited number of students are currently allowed on to college campuses at any one time in line with current public health guidance, with safety measures such as social distancing in place.
Scotland's national clinical director Professor Jason Leitch said: "The college testing programme is voluntary, and I encourage all eligible staff and students to take part regularly to help protect themselves, and keep their friends, families and colleges safe.
