The Technology Proficiency Self Assessment (TPSA) has been used since 1997 in its original form with only a few minor modifications (changing Alta Vista as a search engine example to Google). The survey instrument has retained its reliability even in the evolving arena of educational technology. The survey has been translated to multiple languages including Turkish and Spanish. In this study, the research team focused on similarities and differences among elementary, middle school, high school and university teachers in a native Spanish language environment, regarding technology integration self-efficacy in four areas: Email, World Wide Web, Integrated Applications and Teaching with Technology.
