The government founded ALS to provide everyone with the chance to obtain and finish a basic education in a method that is suitable for their unique circumstances and requirements since every Filipino has a constitutional right to a free basic education. The ALS program would not be possible without the help of the ALS teachers, who volunteered themselves fully to teach and develop the learners skills. ALS teachers must also acquire 21st-century skills that will help them guide and equip the learners. This research study focuses on the demographic profile of ALS teachers and their 21st-century skills. Based on the ALS curriculum and their demographic profile, which includes age, sex, work position, and civil status, this study intends to assess the 21st century competencies of ALS instructors. This research used a descriptive method of research design to provide accurate and valid results. This study includes 84 respondents. Results for overall 21st century skills of ALS teachers revealed that they are equipped with the necessary skills to help their learners develop. Furthermore, the results show that there is no significant relationship between the 21st century skills of ALS teachers and their demographic profile. On the other hand, life and career skills have a significant relationship with their age.
