Teaching is a profession that requires its practitioners to be trained and certified. The training may take the form of pre-service or in-service. The teachers who pass through either of these modes of training are also required to possess ample and reasonable knowledge and skills of the subject matter they teach. In addition, the training that they take should focus on shaping their attitudes towards the teaching profession so that they can adapt, improve or change the reality they find in schools. In addition, they are expected to possess ample experiences of teaching. Purpose. This explanatory study explored the relationship between the training that teacher trainees received at Kemissie College of Teachers Education in Ethiopia and their teaching practice at primary schools. Methodology. The researchers collected the data for the study from pre-service teachers of the college using a questionnaire, interview, document analysis and classroom observations. A mixed approach was employed to collect and analyze the data. The results show that some of the courses contribute less to helping the trainees develop the required competence to teach the subject. There are also neglected but relevant courses. In addition, the practicum program is not being run as it is intended to be run. The relationship between the training that the teachers received and the teaching practice at primary schools is not strong. Therefore, it is recommended that more relevant courses and contents should be given emphasis. The practicum program should also acquaint trainees with the reality at primary schools in order to attain the intended purpose of the program. Supervisors and mentors should also guide the trainees and help them progress in their profession. Conclusion. This study found that the teacher training curriculum focuses on subject area knowledge, professional skills and teaching practices. These components are essential and helpful to train competent primary school teachers. The participants in the study revealed that some of the courses that they attended have contributed positively to their effective teaching of English at primary schools.
