Consideration of cultural and linguistic features is mandated by law and one of the most important contributors to the appropriate placement of diverse learners for special education services. This article describes the results of a pilot project designed to assist rural educators to deliver an equitable and unbiased assessment process for English…

Writing assessments have taken two primary forms in the past two decades: direct and indirect. Irrespective of type, either form needs to be anchored to making decisions in the classroom and predicting performance on high-stakes tests, particularly in a high-stakes environment with serious consequences. In this study, 11th-grade students were…

The use of eligibility for a free lunch as a measure of a student's socioeconomic status continues to be a fixture of quantitative education research. Despite its popularity, it is unclear that education researchers are familiar with what student eligibility for a free lunch does (and does not) represent. The authors examine the National School…

Test bias research with Native American participants is uncommon, although individual tests of intelligence are often used with Native American students to determine eligibility for special education services. Only two studies with minimally adequate sample sizes have addressed the structural validity of major tests of intelligence in Native…

The 10-year review of scales assessing functional impairment by Winters in this issue provides an informative, well-organized, and exhaustive review of the literature. The construct of functional impairment is differentiated from the severity of disorder. Scales in each category are reviewed in a uniform manner covering the following headings:…

The Student Descriptor Scale (SDS) was developed as a validation measure to determine whether students described and counted by states as "severely handicapped" were, indeed, students with severe disabilities. The SDS addresses nine characteristics: intellectual disability, health impairment, need for toileting assistance, upper torso motor…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…

The performance of 566 elementary students enrolled in grades 1-6 from Minnesota, Pennsylvania, and Washington, on direct measures of reading, spelling, and written expression was analyzed to determine the rate of students who would be eligible for special education services by each of four discrepancy criteria. Measures were individually…

Assessments in English that are constructed for native English speakers may not provide valid inferences about the achievement of English language learners (ELLs). The linguistic complexity of the test items that are not related to the content of the assessment may increase the measurement error, thus reducing the reliability of the assessment.…

Five countable indices of writing quality were examined for their suitability in making special education screening-eligibility decisions, based on writing samples from 2,160 students. Even the best index was only moderately efficient. "Percentage of words spelled correctly" was best overall, and "percentage of correct word sequences" was best for…

The effectiveness of representative teacher evaluation instruments for assessing the eligibility of public school teachers for merit pay was evaluated via a literature review. Elementary school principals' (N=200) ratings of teachers were analyzed. Rating instruments may be useful for making initial decisions about who should be eligible for…
