This quantitative correlational non-experimental study examined the predictable relationship between the ACCESS for English Language Learners scale score and the Georgia Milestones English Language Arts (GMAS-ELA) standardized assessment for reclassified fifth-grade English language learners during the 2018-2019 school year. The problem addressed was fifth-grade students continued to perform below grade level on the GMAS-ELA assessment after reclassifying as English language proficient on the ACCESS language proficiency assessment. The purpose was to examine the predictable relationship between the ACCESS scale score and the GMAS-ELA scale score of reclassified fifth-grade ELL students to determine if the ELP assessment scale score's outcome is a predictable indicator of the performance outcome of the GMAS-ELA. The archival data was collected from the school district's Statewide Longitudinal Data System on fifth-grade reclassified students' ACCESS scale score and GMAS-ELA scale score. The research question was examined using the IBM SPSS Statistics Premium 26 software in which Pearson's product correlation and simple linear regressions determined if a predictable relationship existed between the variables. There was no statistically significant relationship between the fifth-grade students' ACCESS scale score and the GMAS-ELA scale score (p > 0.05). The null hypothesis was failed to be rejected. The results indicated fifth-grade students' ACCESS scale score was not a statistically significant predictor of the students' GMAS-ELA scale score. Recommendations for educators' applicable practice were to continue to create formative assessments aligned with standardized summative assessments to expose English language learners to the utilization of the English language on state assessments.
