Communication and teamwork are intertwined, with communication deemed crucial for successful group task execution. This study aims to evaluate the effectiveness of communication and teamwork skills in youth. This single-group pre-and-post-intervention study involved 243 students from four undergraduate colleges. An eight-session communication and teamwork training program was conducted, and efficacy was assessed using a validated semi-structured questionnaire. Chi-square analysis revealed that 55.55% of participants were female, and 44.44% were male. Female participants aged 18 to 20 showed a significant increase compared to males. Results indicated improvements in business communication knowledge, confidence, a comprehensive presentation approach, and a positive communication style. Teamwork and team expertise, as well as recognizing the importance of involving the team in tasks, also improved after the intervention. The study demonstrated significant enhancements in essential communication skills and teamwork among youth, emphasizing the positive impact of the intervention.
