In the literature related to school reform, the term "Trust" has been repeated constantly and has always been
named as one of the essential element of reform in schools. Regardless of importance of trust, there is relatively
little systematic research on trust in educational settings especially in public schools. The results of previous studies
indicate that trust across school lubricates much of a school's day-to-day functioning and is a critical resource as
principals embark on ambitious improvement plans and in general trust is one of the distinctive factors separating
the effective schools from non effective ones (Tarter, Sabo & Hoy, 1995; Bryk & Schnider, 2002).
