The present study was a pilot field project that included pre-test, post-test, and control group. Research sample consisted of 40 male sixth-graders studying at all-boys elementary schools who were selected and assigned into experimental and control groups based on multistage random sampling technique. Tools of this study included Gambrill-Richey Assertion Inventory and Coopersmith Self-Esteem Inventory and Both experimental and control groups had participated in assertive and self-esteem pretest prior to resiliency training. Then resiliency training was provided for experimental group, but not for control group. Immediately after the completion of training course, post-test was performed for both groups. The results of multivariate analysis of covariance (MANCOVA) showed that resiliency training increases students&#39; self-assertion significantly. Therefore, it can be concluded generally that strengthening and training resiliency skills provoke assertive and self-esteem in students.</span></div> Training, resiliency, self-assertion, self-esteem, students 110 119 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-114-2&slc_lang=en&sid=1 Ziaaldin Salari Koohfini 10031947532846001211 10031947532846001211 Yes PhD Student, Department of Educational Sciences,University of Hormozgan, Bandar Abbas Manizhe Ghasemali Kheirabadi 10031947532846001212 10031947532846001212 No MA in Educational Psychology, Shahid Chamran University of Ahvaz, Ahvaz
