This chapter examines collaboration as a factor influencing how graduates apply their learning from educational development programmes and evolve as educators. It highlights that successful teaching collaboration relies on teachers’ awareness of colleagues who share similar teaching philosophies. This awareness depends on having an effective system for teaching observation and ample opportunities for discussing teaching practices. Graduates who engage in teaching collaboration appreciate the opportunity to learn from diverse ideas and approaches, find allies for teaching innovation, and value the benefits of such collaboration for students. When graduates perceive their department as unsupportive of their teaching values, they seek collaborators outside their immediate environment. These external collaborations, though beneficial, are relatively uncommon, suggesting a need for additional institutional support.
