This study investigated the relationship between professionally and personally inviting behaviors of high school principals in the state of Mississippi and: (a) Teacher Job Satisfaction, (b) Principal Effectiveness, (c) Principal as an Agent of School Improvement, and (d) Principal's Invitational Quotient, and (e) The Computed Accreditation Performance Index of their respective school district. The foundation for this study evolved as an extension of earlier research (Asbill, 1994) that examined the value of Invitational Education Theory (IET) as a workable theory for educational leaders in the school setting.
