The Cronbach's alpha were 0/78, 0/80, 0/67, 0/60, 0/42 for behavioural, agency, self-regulation, affective , cognitive and %78 for Student engagement in school. Also Confirmatory factor analysis confirmed these factors.To test the validity of instrument, Student engagement to school scale(Wang, Willett & Eccles, 2011) was used and correlation of 0/44 was concluded. The results permitted to find this scale presents psychometric qualities and can be used in research and psychoeducational practice, to assess the multidimensional students’ engagement in school.
