During the COVID-19 pandemic, education systems policymakers realized the importance of being able to communicate using technology and to fulfill their academic obligations. As a consequence, a different approach to education followed: blended learning. A literature review revealed a lack of psychometric tools related to blended teaching readiness in Greece. Hence, the purpose of this study was the translation from English to Greek and the adaptation of the "Blended Teaching Readiness Instrument" (BTRI). The research instrument assesses five instructional modules: teacher attitudes, learning activities, use of digital data, learning environments, and online interaction. The present study showed that the two versions of the BTRI, the original and the targeted, are fully equitable in terms of conceptual and adaptation meaning, with concepts of the same meaning in the Greek language. The final translated version corresponds to the original English version.
