Understanding student-teachers' decisions to enter and stay in the teaching profession after graduation could help teacher educators to find appropriate procedures to enhance commitment to teaching. This study classified student-teachers based on their levels of commitment to teaching, and described these types based on student-teachers' motivation to enter the teaching profession and their perceptions of the teaching profession and environmental aspects e.g. school condition and significant others. Thirty-seven undergraduate student-teachers from the Dar es salaam University College of Education in Tanzania were interviewed. Four student-teacher types from our results were identified: (1) committed passionate, (2) committed compromisers, (3) undecided and (4) uncommitted. Implications from the findings include the importance of designing teacher education curriculum in a way that caters for the needs of student-teachers in each type in order to enhance their commitment to teaching.
