The achievement gap between private and public school college-bound students has continued to widen each year since 1972. The researcher studied the relationship of Christian school college-bound students’ religiosity/spirituality using a validated survey instrument and their achievement as measured on the Scholastic Aptitude Test. The literature implies a relationship, but there is a gap in studying homogeneous religious groups. Therefore, the researcher selected a homogeneous grouping, Texas Christian high school college-bound seniors, as the sample for this study. The researcher obtained permission to use the Religiosity and Spirituality Scale for Youth (RASSY) survey instrument and included demographic and score data from student Scholastic Aptitude Test (SAT) reports. The researcher used Pearson r to analyze relationships between students’ religiosity and spirituality as measured by the Religiosity and Spirituality Scale for Youth (RASSY), years enrolled in a Christian school, and students’ composite critical reading, mathematics, and writing SAT scores. Results indicated a positive and significant relationship between years enrolled in a Christian school and composite SAT scores.
