Assessment Principles and Guidelines for ELLs with Disabilities
Published by the National Center on Educational Outcomes, this document looks at improving the validity of assessment results for English language learners with disabilities. This report presents five core principles of valid assessments for this population of students, along with a brief rationale and specific guidelines that reflect each principle. Principle 1: Content standards are the same for all students. Principle 2: Test and item development include a focus on access to the content, free from bias, without changing the construct being measured. Principle 3: Assessment participation decisions are made on an individual student basis by an informed IEP team. Principle 4: Accommodations for both English language proficiency (ELP) and content assessments are assigned by an IEP team knowledgeable about the individual student’s needs. Principle 5: Reporting formats and content support different uses of large-scale assessment data for different audiences.
