Stunting remains a significant health issue with relatively high prevalence rates at the local level, including in Gentan Village. Early detection through Posyandu clinics has not been optimal due to the limited capacity of community health workers to screen for growth in young children. Therefore, capacity building for these workers through training is essential. The aim of this study is to determine the improvement in community health workers ability to detect stunting at an early stage following training. This activity employed a community nursing care approach comprising the assessment, diagnosis, planning, implementation and evaluation stages. The target group for the activity was 27 health cadres. The intervention was carried out using a one-group pre-test post-test design and observation through the provision of education on stunting screening, demonstrations of anthropometric measurements, and the completion of the Kartu Menuju Sehat (KMS) chart. The analysis was carried out by comparing the pre-test and post-test results to assess changes in the volunteers knowledge and skills following the training. The data are presented as percentages and frequency distributions. The results showed an increase in the health workers’ knowledge following the intervention. The number of health workers in the ‘good knowledge’ category increased from 12 (42.9%) to 27 (100%). All cadres (100%) demonstrated good skills in performing anthropometric measurements. The cadres’ ability to complete the KMS charts also improved from 11 cadres (39.3%) to 21 cadres (75.0%). There was an improvement in the cadres’ knowledge, skills and ability to carry out the early detection screening process.
