21st century learning has learning demands that lead to HOTS, character education, literacy skills, and 4C (Critical, Creative, Communicative and Collaborative) that can be achieved through the development of HOTS-based E-LKPD combined with indicators of critical thinking skills. Based on the pre-introduction conducted by researchers, it was found that the competency test questions and description questions that have been used in learning are still narrative and prioritize cognitive aspects so that they are not yet relevant to the characteristics of HOTS. This research goal is to develop E-LKPD teaching materials primarily based on higher order thinking skills in financial accounting topics and improve students' critical thinking skills. The research subject consisted of 20 students of class XI Accounting at SMKN 6 Surabaya. The research development Model is 4D (define, design, development, disseminate) without disseminate stage. The research instruments are observation sheet, interview sheet, review sheet, validation sheet, evaluation sheet, and student response questionnaire sheet. The results of Development Research obtained the average results of expert validation of HOTS-based e-LKPD of 87.3% showed that the interpretation is very feasible to use. N-Gain score test obtained an average score of 0.62 with moderate criteria on the results of the critical thinking skills test. Learners ' response to E-LKPD based on HOTS get results of 96.6% with very good criteria. So that the use of HOTS-based E-LKPD in learning has been declared valid and very feasible because it can improve critical thinking skills.
