This chapter looks at a practical example of staff development and considers how professional development of teachers should be an essential component of enhancing provision within higher educational institutions not just in terms of pedagogy but also in respect of developing programmes and marketing those programmes. Set within the specific context of English Language teaching for international students, the research is based on a case study of two trainee teachers on a DELTA programme (Diploma in English Language Teaching for Adults). These teachers have been interviewed at two different stages of their development, firstly whilst doing the DELTA course, and then one year later, by which time they have completed the course. Through analysing their responses in a qualitative fashion, the author examines whether teacher development has a positive impact on the higher educational institution as a whole, and whether it leads to an improved student experience or a heightened consciousness of that student experience on the part of teachers. At the heart of this chapter, there is a metaphor taken from Medical Science to define the best approach to teacher education and development, namely, what the author labels an intramuscular approach. The author takes this term from a medical process of giving injections that are placed deep within muscles so that the particular drug or medicine is released slowly over a period of time rather than in a standard one-shot manner. There is no quick fix solution to teacher development, and having a long-term vision contributes far more to organisations in terms of the ultimate student experience.
