If you need a questionnaire on leadership skills in secondary schools, then 18 items questionnaire on managerial, behavioral and transformational leadership skills can be provided.

I think you are better off tailoring your questionnaire according to your research objectives and respective variables.

I would recommend reading the following article in the Google Scholar:

- A. Olu Oyinlade (2006) A Method of Assessing Leadership Effectiveness, Performance Improvement Quarterly, Volume19, Issue1, Pages 25-40. https://doi.org/10.1111/j.1937-8327.2006.tb00355.x

Prof Andreas Wallo

thank you for answering,

I am more interested in an effective leader's daily actions and behaviors, such as Visioning, team building, Emotional intelligence, and more.

Thank you all, i appreciate your answers.

Sachin Suknunan, Mohamed Saheed Bayat and I have done a few articles on ethical leadership and its impact on employee engagement. Please feel free to view them.
