This study describes prospective teachers' perspectives on collaborative problem-solving (CPS) in mathematics. The study employed a 20-item questionnaire distributed to 47 prospective mathematics teachers in Indonesia. The questionnaire responses were scored, and two participants with the highest and lowest mean score were interviewed. Despite being quite similar in perspectives on perseverance and interest in collaboration, the prospective teacher with the highest mean score showed more openness to problems and the value of teamwork. Further research can be done by investigating how prospective teachers' perspectives relate to their knowledge of CPS or teaching practices.
