English language proficiency (ELP) assessments are used to evaluate reading, writing, speaking, listening, and overall comprehension proficiency in English. There are two main types, or purposes, of ELP assessments. The first type of proficiency assessment is usually used at least once to help identify a student as an English language learner to be eligible for services. But it may also be used periodically for other purposes, such as to check a student's growth. The second type of proficiency assessment is used by a state to annually track the language proficiency of students already identified as English language learners. The second type of ELP assessment is the focus of this section. Because some students who are identified as English language learners may also have disabilities, it is important to consider how those students participate in ELP assessments along with their peers.
