To measure the level of media literacy, a measuring instrument in the form of an assessment is needed. The instruments used in the study were adopted from Son which is a non-test in the form of a closed questionnaire that had been revised and validated with the conditions of students in Banda Aceh. The study aims to examine construct validity of digital media literacy instruments used. The population in the study was 242 student teachers in Biology Education Department at a public university in Banda Aceh. The sample were 168 students selected using purposive sampling. The study applied CFA method. The results of construct validity of the instrument that can be seen in the validity of all the observed variables were good with t value > 2 and SLF >0.3. Moreover, the construct reliability were categorized very high (0.80<CR 1.00) and high (0.60<CR0.80). This indicates that the instrument can be used to measure the level of digital media literacy of student teachers.
