Abstract- The objectives of this research are 1) to study the current situation of teacher characteristics, and 2) to propose development guidelines to enhance these characteristics at Nanning Nanshan Art Vocational School. The population for this research was 112 full-time teachers at Nanning Nanshan Art Vocational School, and the sample was 86 teachers selected by simple random sampling according to Krejcie and Morgan (1970). The research instrument was a teacher self-assessment questionnaire consisting of five core dimensions: teacher self-efficacy, teacher personality, teacher burnout, organizational support, and teacher digital literacy. The statistics were frequency, percentage, mean, standard deviation, and content analysis of the suggested guidelines. The questionnaire demonstrated excellent reliability (Cronbach’s α = 0.974) and high construct validity (KMO = 0.947, p < 0.001). The results were found that: 1) the overall levels of teacher self-efficacy (M = 4.21), teacher personality (M = 4.05), organizational support (M = 3.53), and teacher digital literacy (M = 3.83) were at a high level, while teacher burnout was at a medium level (M = 3.48); 2) based on the empirical results and literature review, practical development guidelines were synthesized for each dimension, focusing on relatively weaker aspects such as inspiring students’ artistic learning, alleviating emotional exhaustion, enhancing recognition of art teachers’ work, and strengthening digital ethics and privacy protection. These guidelines can support Nanning Nanshan Art Vocational School and similar institutions in planning systematic teacher development programs.
