Background: The STEM education system has garnered significant interest due to its innovative approach in creating a multidisciplinary and integrated knowledge structure that connects science, technology, engineering, and mathematics, and allows students to apply scientific knowledge in a comprehensive and holistic manner. Consequently, evaluating the teaching methods of teachers in accordance with STEM standards is critical. This assessment should take into account various educational objectives, including cognitive, skill-based, and emotional aspects. Purpose: This study aimed to evaluate the creative teaching practices of mathematics teachers for gifted students according to STEM standards. Method: The study applied the descriptive analytical method and developed a rating scale for evaluating creative teaching practices based on STEM standards, verifying the psychometric properties in several ways. The study sample consisted of 64 teachers of mathematics for gifted students. Results: The results showed that the degree of application of creative teaching practices by the teachers of gifted students according to STEM standards was at the moderate level in three domains: planning, implementation, and assessment. Conclusions: Despite the importance of achieving integration for STEM, the actual teaching practices of teachers of the gifted according to these standards were generally average and did not reach acceptable and ambitious levels.
