In order to encourage school districts to include students with Limited English Proficiency (LEP) in educational assessments, this report discusses issues involved in assessing students with LEP. Topics include: (1) the role of testing in education and the different types of tests mandated by educational reform legislation; (2) characteristics of students with LEP and relevant demographic data; (3) factors within the student, the student's environment, and the testing environment that can influence the test results; (4) modifications and adaptations that make assessments more appropriate for students with LEP; (5) research findings related to current assessment practices in states and school districts across the country; and (6) research findings from large-scale assessment at the national level. Findings from the literature review are highlighted, including the trend toward large-scale assessments, the important role of testing, the growing population of students with LEP, the lack of a standardized definition for LEP, the need for clear guidelines for testing of students with LEP, the need to consider certain factors when language minority students and students with LEP are tested, and the need for states to pool their knowledge about students with LEP and their assessment resources.
