This study examined parents' educational qualifications and marital status as a correlation of social adjustment among secondary school students in Delta North Senatorial District. Three research questions and three null hypotheses guided the study. A correlational research design was used in the study. The population of this study is 16,473 senior secondary II (SS II) students from all the public secondary schools in Delta North Senatorial District. The sample for this study was 455 secondary school students. A multi-stage sampling method was used in this study. A questionnaire was used for data collection. The face validity and reliability of the instrument were assessed. The reliability of the instruments was estimated using the internal consistency reliability method, computed using Cronbach's alpha.These tests yielded reliability coefficient values of 0.89. The questionnaire was administered to 455 SS II students. However, only 439, which represents approximately 97% of the total number of administered questionnaires, was retrieved and used for data analysis. The data was analysed using descriptive statistics, and the Pearson Product Moment Correlation coefficient (r) and coefficient of determination (r 2 ) were used to answer the research questions. All hypotheses were tested using linear and multiple regression at an alpha level of 0.05. The findings of the study revealed that: there is no significant correlation between parents' educational qualifications and the social adjustment of secondary school students in Delta North Senatorial District; there is no significant correlation between parents' marital status and the social adjustment of secondary school students in Delta North Senatorial District. There is a significant joint influence of parents' educational qualifications and marital status on the social adjustment of secondary school students in Delta North Senatorial District. Based on the findings, it was recommended that school counsellors should regularly provide individual and group counselling to students who are struggling with social adjustment, irrespective of their parental parents' educational qualifications and marital status.
