This study examined the degree and levels of parent trust and involvement in lower secondary and high schools in Turkey. Survey data were obtained from 429 participants working for state schools during the 2012–2013 education years. We used zero-order correlation coefficient, independent samples t test, and, when significant differences were observed between groups, Cohen’s d coefficient. In addition, multiple linear regression analysis was used to determine whether trust in school, school level, and age significantly predict parental involvement. Findings suggest that parents have almost high trust in schools and also participate in school activities.
