Peer teaching can be defined as the transmission of knowledge between colleagues from the same or similar stages of academic training. Near peer teaching (NPT) is a similar variant, in which higher level students (tutors typically 2-5 years ahead of the tutee in the academic program) mentor their junior classmates (tutees) by temporarily assuming the role of the instructor. This method has been utilized in many university and medical school settings (Evans and Cuffe, 2009;Jackson and Evans, 2012;Cantwell et al., 2015;Riddell and King, 2016). In the United Kingdom, the General Medical Council's guidelines, Tomorrow's Doctors: Recommendations on Undergraduate Medical Education, states that a medical graduate must "function effectively as a mentor and teacher" (GMC, 2009). Therefore, implementing an NPT program within an undergraduate curriculum stands to prepare medical students for their future role as educators.We have read with great interest the recent article published in ASE by Bruno et al. (2016), and we applaud their work; however, as the authors mentioned, there were several limitations. We agree that the sample size and the number of sessions involved were too small to draw any longstanding conclusions. We would like to bring to attention another important limitation. With regards to the analysis of student perceptions regarding the program, the authors based their findings on comments from the majority of students (74.3%) who attended a single session of the peer teaching program in human anatomy (Bruno et al., 2016). In our opinion, every student must complete at least 80% of the course in order to have a valid perception of the entire program.Five years ago we designed and implemented a human anatomy course in our medical school at Autonomous University of Nuevo Leon in Monterrey, Mexico, integrating NPT. We were faced with several obstacles: curriculum reform, an increase in student enrollment, low faculty-to-student ratios, and an insufficient number of cadavers for gross anatomy laboratory practical sessions. The course was reformatted to last 18 weeks and was divided into four learning modules: theory, clinical hours, anatomy imaging, and laboratory modules (Dur an et al., 2012). The theory module consisted of lectures that lasted one hour daily, five days a week, and were carried out in a traditional manner (one professor with 50 students). The laboratory section (three hours per week) was based on clinical reasoning activities guided by near-peer instructors who were previously trained by professors with regards to the subject matter (Dur an et al., 2012).When we first implemented this program in 2011, a total of 700 first-year students were enrolled in the human anatomy course. At the end of the semester more than 500 had agreed to answer a survey we designed to collect and analyze their opinions on the course design. We analysed qualitative aspects of the NPT program (i.e., communication skills, motivation, and performance) and found that the majority of students rated all of these aspects as e...
