English Language Learners are students who speak at least one language other than English. English Language Learners have lower standardized test scores than their native English speaking peers. As a result, ELLs are often put into remedial classes that might not have been necessary if they were native English speakers. Also, there is the threat of not passing classes or not graduating from high school because of standardized testing. The purpose of this qualitative phenomenological study is to examine the lived experiences of ELLs during standardized tests and determine the impact the tests have on their mental health due to the fact that ELLs perform lower on standardized tests than their non-ELL peers. The participants consisted of fifteen ELLs from a rural Minnesota high school, grades 9 through 12. All participants' ACCESS scores ranged from a 2.5 to a 4.0 on the previous year's test. Each participant was interviewed individually over a video call in a semi-structured interview. The results of the research study showed that participants felt positive emotions when speaking to a trusted adult about standardized tests and standardized test scores. Participants prepared for their standardized tests both at home and in class. The study showed that participants felt nervous and anxious around standardized testing. However, participants felt good after taking standardized tests. The participants also reported changes in eating and sleeping habits around the time of standardized tests. More research is needed to determine if English Language Learners have similar experiences to native English speakers around their standardized tests. The mental health effects of standardized testing have not been quantitatively studied in English Language Learners.
