Distance learning has been steadily growing in popularity over the past 20 years. The majority of distance learning has taken primarily taken place at the collegiate level. Although distance learning has been used minimally at the K-12 level, the pandemic in the spring of 2020 put it at the forefront of all levels of education. Now that education has returned to a sense of normalcy, there are lessons to be learned from the online experience. The majority of the research for distance learning pertains to the collegiate level. This study sought to provide insight for secondary leaders and university education preparation programs on teachers' preparation and continued professional development to improve self-efficacy for instructing in the virtual setting. This causal-comparative study was framed from the beginning and veteran teachers' perspectives to determine if preservice practices have changed or if experience in the classroom carries over to the online setting. A statewide survey was distributed to secondary educators to measure their levels of self-efficacy for virtual instruction and gather information on their backgrounds and preparation. Findings indicated there was no statistical significance between beginning and veteran teachers for online instruction.
