The current review determined the importance of professional development (PD) in K-12 engineering education. It highlighted the challenges teachers face and opportunities available for students to enhance their problem-solving and critical-thinking skills. The review used research studies on PD focusing on challenges and opportunities teachers and students face in K-12 engineering education. Data was gathered using the last ten years (2015-2024) from authentic published studies from databases (Springer, Wiley, Taylor & Francis, MDPI). This review study used keywords that include; "K-12 Engineering Education," "Professional Development in STEM," "Active Learning Strategies," "Challenges in Engineering Education," and "Opportunities in K-12 STEM”. Seventeen articles were extracted from the data and included as final studies. Research results showed that successful PD programs that use project-based and gamified learning approaches deliver meaningful improvements to internal education competence and student problem-solving ability for teachers. Teachers face obstacles because of restricted resources, insufficient teacher development, and institutional obstacles. Findings showed that PD can help teachers implement innovative teaching methods for engineering education in K -12 classrooms.
