Mentors are allocated a mentee group of 8-10 mentees, usually in the same department as them. They send their mentee group an email towards the end of the summer to welcome them to LSE and answer their pre-arrival questions. They are also expected to answer questions via email throughout the academic year.
Mentors also facilitate mentee meetings to encourage their mentees to meet with other students who are living off campus. Mentors are expected to hold a mentee meeting during the main Welcome period (Monday 20 - Friday 24 September 2021). They also hold further meetings during Michaelmas Term and occasionally throughout their mentees' first academic year.
It's not particularly time intensive, but mentors have considerable impact in terms of providing support, facilitating early social networks and signposting their mentees to the appropriate services.
