The purpose of this study was to examine the self-reported competency level of Ohio principals in each of the five 2018 ISTE Standards Education Leader domains, measured by the 2018 Principal Technology Leadership Survey. This study also sought to investigate if the differences in self-reported technology leadership competency correlated to a principal's demographic characteristics or the current level of technology implementation in the school building. This study used a quantitative, descriptive survey design to assess the perceived level of competency of each of the five domains of the ISTE Standards-EL of Ohio principals. Results from this study indicate that Ohio principals display relatively equal proficiency in all domains of the technology leadership standards. Results also showed that principal personal and school demographic factors do not significantly correlate to self-reported domain mastery. Finally, this study indicated a statistically significant correlation between the level of use of a recent technology initiative and the principal's self-reported proficiency in each of the five domains of the 2018 ISTE Standards-EL. Further research implications are also discussed. [The dissertation citations contained here are published with the permission of ProQuest LLC. Further reproduction is prohibited without permission.
