چکیده (انگلیسی):

This quantitative study investigated reasons that school principals recommend non-renewal of probationary teachers' contracts. Principal survey results from three regions of the US (Midwest, Rocky
Mountains, & Southeast) were analyzed using the Kruskal-Wallis and Mann-Whitney U statistical procedures , while signicance was tested applying a Bonferroni Correction. The study examined prioritized
reasons for teacher contract non-renewal, behaviors observed from ineective teachers, and complications
which work against addressing ineective teaching. Results indicated that principals from all regions are
more willing to initiate contract non-renewals when there have been ethical violations or inappropriate
conduct. All regions' principals reported that teacher instructional skills are more important than subject
content knowledge and dispositions in teacher contract non-renewals; however Southeastern principals
placed more importance on subject content knowledge than their counterparts. All regions' principals
strongly identied the barrier of time; whereas only principals from the Midwest and Rocky Mountain
identied teacher unions, laws protecting teachers, and collective bargaining agreements as complications
to addressing ineective teachers.
