Testing ELL Students for a Learning Disability

The article "Special Considerations for Evaluating ELL Students for LD" by Linda Broatch, M. A. (http://www.greatschools.org/special-education/LD-ADHD/1153-special-considerations-for-evaluating-ell-students-for-ld.gs) discusses the high-quality features that need to be in place in order to get the most accurate results when testing ELL students to determine whether they have a learning disability. It echoed many of the same components as the article I read in my previous post, such as the fact that information needs to be gathered from a variety of sources: parents, teachers, ESL teacher, and school psychologist. It also mentions the importance of using formal and informal assessments in a variety of settings in order to get a more accurate picture of the child's language ability and whether their difficulties stem from learning a new language or a learning disability.
This article goes on to explain the necessary conditions for testing, and it briefly describes the two broad areas of assessment: oral language and reading. In regards to the testing, it needs to be culturally sensitive, meaning that no assumptions are made about the child's cultural knowledge. The testing process also needs to be implemented by a trained professional using tests that have been proven reliable for ELL students. The oral assessment is given in one or both of the student's languages depending on their needs, and it evaluates several factors such as vocabulary, conceptual understanding, and conversational and formal language abilities. The article does not specify which language the reading assessment is given in, but it evaluates students' phonological skills, phonemic awareness, decoding skills, and automaticity.
The information presented in the article is helpful in that I better understand the testing process, but really it is not something I would be directly involved in apart from providing information about the student's language and academic abilities in the classroom. I need to narrow down my search more and look for information about the signs that an ELL student may have a learning disability and the steps I would need to take from there. I also would like to find teaching methods that would support the learning of ELL students with a learning disability in the general ed. classroom.
