The purpose of this study was to adapt Preservice Teachers' ICT Competencies Scale which was developed by Tondeur, Aesaert, Pynoo, Braak, Fraeyman, and Erstad (2017) into Turkish. The participants were composed of 206 preservice teachers studying at Gaziosmanpasa University during 2017-2018 academic year. The results showed that the Turkish version fits the original two factor structure. The correlation coefficients between the data obtained from the Turkish version and the data obtained from General ICT Tendency, Reality Shock Expectation, and Prospective Teachers' Perceived Competencies about Integrating ICT into Education were examined to test convergent, divergent and concurrent validity. The results indicated that the data obtained from the Turkish version of the scale were valid. Moreover, the Cronbach alpha coefficients indicated that the data were internally consistent. In conclusion, the Turkish version of Preservice Teachers' ICT Competencies Scale was determined to have good psychometric properties to be used in Turkish context.
