This study seeks to monitor family and career maturity relationships among middle school final-year students as an early stage of career guidance in Moroccan schools. The survey research consisted of the Arabic version of Crites’ career maturity scale, along with a series of family-related variables that the study assumed were having an impact on the career maturity of children, mainly parents’ occupations, their educational level, and cultural resources available to the family. The study sample includes 180 learners from six public middle schools, all of which belong to a rural province of the Fez Meknes region. The results of this study show low career maturity among the majority of learners involved in the study, with a direct and statistically significant effect of family variables on children’s career maturity and a difference in the degree of impact between fathers and mothers. The paper concludes with possible key points for guidance interventions in educational institutions to develop the career maturity of learners and to improve family-school relationships and collaboration on this matter.
