The purpose of this study was to evaluate the effect of a school counselor-led classroom intervention, Student Success Skills (SSS) program (Brigman & Webb, 2010), on Grade 5 Hispanic students' self-regulation, school attendance, and test anxiety. The study used non-identifying archival data from a random controlled trial (RCT) collected at 30 elementary schools in one school district during the school year 2012-2013. Attendance was collected at the end of the school year when students completed Grades 4, 5, and 6. Data were collected at three points: pretest, posttest 1, and posttest 2. A series of multivariate analysis of covariance (MANCOVA) tests and univariate analyses were conducted to determine statistical significance between the treatment group and comparison group in self-regulation, school attendance, and test anxiety. Effect sizes using a partial eta square were calculated for each dependent variable. The results support the Student Success Skills (SSS) classroom program (Brigman & Webb, 2010) implemented by certified school counselors was documented.
