not sure if such a tool exist, but we have recently developed such a tool to assess the knowledge of nurses and midwives on analgesics and lactation. You might be interested in the methodology applied ? https://www.mdpi.com/1660-4601/18/21/11555 (open access)
This is used with dietitians but could easily be adapted for medical students. Becker GE, Quinlan G, Ward F, et al. Dietitians supporting breastfeeding: a survey of education, skills, knowledge and attitudes. Irish Journal of Medical Science (1971 -) 2020;190:711-22. doi: 10.1007/s11845-020-02384-3
It is very important to first establish what your students are expected to know or be able to do at the end of their course. A general medicine student is likely to need different competency than a midwifery student, for example. Some tools such as the BFHI tools are designed for students or practitioners who have responsibility for directly assisting a baby and mother to breastfeed and are undertaking a course of 3-5 days at least including practical sessions. A general medical student (pre any specialization) may only need an awareness of the importance of breastfeeding, the risks from not breastfeeding (for mother, baby, family, wider community and environment), and a discussion of what health care and community practices support or hinder breastfeeding establishment and continuance. Training to work in pediatrics or in public health, or in orthopedics or eye surgery, would require different competencies related to breastfeeding.
