The purpose of the 7-year longitudinal study was to examine the College Assistance Migrant Program (CAMP), a student services intervention, to determine its impact on migrant student achievement in the California State University (CSU) system. Participants included 336 migrant students who were enrolled as first-time, full-time freshmen in fall 2002 to spring 2009 from six of the 23 CSU campuses with CAMP federal program funding. The comparison groups were Latinos and other students from the general student population for a total of 9,362 student level data records. The study intended to address one overarching research question: Does the CAMP intervention have an impact on migrant student achievement? The Analysis of Variance (ANOVA) and Chi-Square Test of Independence were used to explore differences among CAMP, Latino, and other students from the general population. The variables used to determine academic achievement included persistence, first year and cumulative grade point average, and baccalaureate degree attainment. Data findings reported CAMP was having a positive impact on migrant student participants enrolled in the program.
