This study aimed to find out the difficulties of proof experienced by undergraduate students. The type of research used was descriptive case studies. This research was conducted on 12 junior undergraduate students of the Mathematics Education Department at one of the universities in Yogyakarta. Data in this study were obtained through diagnostic tests and interviews. The most dominant difficulty in proving was the difficulty of construction and understanding the proof difficulties in constructing and evaluating mathematical proof. Those happened because undergraduate students were considered not able to integrate the existing proof by proving that it is done as a complete proof of a case. This difficulty was caused by a lack of accuracy or even prior knowledge that was not sufficient. Lack of relevant knowledge both in the use of theorems and notations was another case of difficulty in proving. © 2019 IOP Publishing Ltd. All rights reserved.
