Several UK University Chemistry Departments have former secondary school chemistry teachers employed as School Teacher Fellows (STF) who are heavily involved in outreach work and a range of teaching responsibilities. This study looks at the outreach role from the point of view of several of the STFs; the benefits, and the barriers and how this role can be developed further. A reflective exercise, asking STFs to write a letter to themselves to advise any new incumbent was used to generate data. This mode was preferred to a formal interview after consultation with STFs. All the responses were analysed in terms of their relationships, motivations and other aspects of their posts. It is concluded that the STF provides a number of unique opportunities to progress relationships between university and secondary and primary schools, to assist new undergraduates in making an effective transition from post-16 study to undergraduate study and to review, support and progress teaching practice at tertiary level. However, barriers to the effective utilisation of STFs include; appropriate support and recognition at the tertiary institute and funding.
