We thank Li and Liu for their thoughtful and constructive commentary [1] on our study [2]. We are pleased that our use of constructed-response items, Rasch modelling and expert-led content validation was recognised as a meaningful contribution to the assessment of sono-anatomy interpretation [1]. We acknowledge the limitations identified and offer clarifications and future directions for our work.
