Each level of education has different teaching difficulties so that teachers must be skilled and adaptive in teaching. This study aims to compare the teaching difficulties of elementary and senior high school teachers in implementing Physical Education (PE) learning online. This study used a quantitative approach with a comparative design using teaching skills instruments from Maksum, consisting of 19 skills aspects circulated through Google form involving 45 participants. The results of the descriptive analysis indicated that senior high school teachers are more difficult to open and organize learning. Meanwhile, elementary school teachers find it more difficult to close the lesson. Furthermore, the most difficult teaching skills for senior high school teachers are "teachers implement strategies to optimize student practice." Otherwise, the most difficult for elementary school teachers is the "teacher breaks down the teaching assignments according to the students' abilities." Meanwhile, both groups were equally easy to teach on the skill indicator "the teacher's treatment is fair, not differentiating between male and female students". Despite the fact that the discrepancies were not statistically examined, the current study convincingly reflects the obstacles that both elementary and senior high school instructors face in terms of teaching skills. However, the study did not look into PE teaching skills utilizing ICT indicators. As a result, future research may construct learning models and investigate further on PE teaching skills based on student characteristics, as well as the use of reality augmented technology to improve PE lesson quality.
