Recruitment of undergraduate participants began immediately after students were admitted to the College of Chemistry in April. The program was advertised to all junior and senior transfer students in the Berkeley College of Chemistry via email at multiple points throughout the summer before commencement of the program. The program was first advertised as part of a panel on programs available for transfer students at Berkeley, held during a recruitment weekend and open to all transfer students recently accepted to UC Berkeley. The main source of advertisement to the TSMP was through an email sent to all incoming transfer students to the College of Chemistry, describing the program and including a form for interested parties to sign up. This led to 35 junior transfer students and eight senior transfer students signing up for participation in the TSMP. No application process was required; thus, all students who signed up were able to participate in the TSMP. All junior TSMP participants were matched with a graduate student mentor.
