The MLitt in Archaeological Studies secured a 94 per cent satisfaction rate, up from 70 per cent in 2021.
The national survey allows students to provide feedback on areas including learning and teaching, assessment and feedback, and organisation and management.
Overall, the UHI received a score of 95 per cent student satisfaction in the 2022 survey, meaning it has achieved the highest rating of any Scottish university and has been ranked fourth out of the 91 participating institutions across the UK.
Coordinated by Advance HE, the Postgraduate Taught Experience Survey invites students to have their say on taught postgraduate university programmes. Students are asked about areas including teaching, assessment and support.
Respondents rated UHI particularly highly for organisation, engagement, teaching, assessment and support.
Commenting on the results, Dr Iain Morrison, Dean of Student Experience, said: “These are exceptional results. Students are the best judges of what makes a good education and to be rated highest in the country is to the great credit of our wonderful staff.
“Coming so soon after our extremely high undergraduate student satisfaction results, this survey confirms that UHI really should be the first choice for anyone considering postgraduate study this year.”
