Technical guidance is an important strategy to strengthen personnel competency, yet its effectiveness must be evaluated systematically. Objective : To analyze the effectiveness of OHS technical guidance using the Kirkpatrick Model level 2 evaluation. Research Methods / Implementation Methods : This descriptive-analytical study employed a one- group pre-test post-test design. Pre-test assessments were conducted before participants received the training materials, followed by post-test assessments afterward. A total sampling technique was used, involving 25 participants of the OHS Technical Guidance for the Workplace Environment organized by Balai K3 Samarinda on October 21–24, 2025. Results : Statistical analysis showed a significant difference between pre-test and post-test scores, indicating an improvement in participants’ knowledge following the training sessions. Conclusion / Lesson Learned : The OHS Technical Guidance for the Workplace Environment was effective in improving participant knowledge and was successfully implemented with a well- executed training process.
