This study highlights the importance of educational leaders' responsibilities in virtual spaces, as they are perceived by school faculties and provides a validated tool to measure teachers' perception of a "principal's leadership presence in social media networks". 235 Israeli teachers participated in the study--180 (77%) females and 55 (23%) males, using a questionnaire consisting of 14 items scaled in a 6-point Likert format. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) reveal four modalities of the principal's on-going leadership presence in social media networks: branding and communicative, transformational, supportive-protective and enforcement presence. The questionnaire may provide principals and educational policy designers with a plan to regulate the socio-professional relationship among a school's stakeholders.
