The present paper has intended to construct, validate and estimate the reliability of the questionnaire of Technology competencies of student-teachers at Shahid Rajaee teacher training university in Tehran. To do so a questionnaire was developed after a systematic review of literature on theories of technology competencies. Through a random cluster sampling a sample of 60 student teachers of Shahid Rajaee teacher training university was selected and the questionnaire was administered. The instrument included 49 items. Item analysis such as item discrimination and loop, construct validation (factor analysis) and reliability analysis (Cronbach Alpha) were utilized. In Factor analysis, three factors were identified as technology knowledge, knowledge consolidation and knowledge production. The reliability of the questionnaire turned out to be .98.The results indicate that the instrument is both reliable and valid and can be readily used to assess student- teachers’ technology competencies.
