When LEP students are exempted from standardized assessments, no one is held accountable for their progress, and results are not representative because a significant segment of the population at large has been excluded. When LEP students are included in standardized assessments with modifications, the effectiveness of the assessments is uncertain. There are numerous obstacles to collecting and reporting data in order to assess the effectiveness of policies and services affecting LEP students and to assess their achievement. In general, obstacles such as those have contributed to the lack of data and monitoring of academic achievement of LEP students. Rivera et al.
Policies are inconsistent across states and even within states.
Some states have policies that both exempt and allow LEP students to take certain statewide assessments with modifications.
