This study investigates the confidence levels of Thai secondary teachers in using digital technology and their demand for professional development (PD) programs. A questionnaire was designed, covering four key areas: digital literacy, practical application of digital technology, problem-solving skills, and adaptability. The results revealed that teachers generally demonstrated either moderate or strong confidence in their digital skills, alongside a notably high demand for PD programs. Interestingly, these findings remained consistent across various demographic variables, such as age, teaching experience, gender, and educational background. Consequently, the study suggests an immediate need for in-service training programs for Thai teachers. However, it's important to note potential limitations, including the sampling method used and concerns about the questionnaire's validity and reliability.
