Parental involvement is significant in the improvement of students’ learning. The study determines the parental involvement and student readiness in Mathematics and its relationship. Descriptive correlation method of research was used in the study. There were 208 grade 7 students from secondary schools in Davao City as sample respondents. Slovin formula was used in the determination of sample size. Questionnaires were the research instrument used in the gathering of data and was presented to the panel of examiners for content validity. Mean, Pearson Product Moment Correlation and linear regression were the statistical tools used in the study. The level of parental involvement is high and the student readiness in Mathematics is very low. The grade 7 students revealed readiness in grade 4 Mathematics. There is no significant relationship between the parental involvement and student readiness in Mathematics. This implies that student readiness in Mathematics is not dependent on parental involvement. The parental involvement is not a predictor of the student readiness. This implies that there are other variables that predicts student readiness but not attributed to parental involvement.
