In the service of educational accountability, student achievement tests are being used to measure constructs quite unlike those envisioned by test developers. Scores are compared to cut points to create classifications like "proficient"; scores are combined over time to measure growth; student scores are aggregated to measure the…

The use of test scores as a performance measure in high-stakes educational accountability has become increasingly popular since the enactment of the No Child Left Behind Act of 2001 (NCLB), which imposed sanctions such as the threat of losing federal funds unless a state implemented a school accountability system that measures student progress…

The inevitable responses to high stakes testing, wherein students' test scores are highly consequential for teachers and administrators, include cheating, excessive test preparation, changes in test scoring and other forms of gaming to ensure that test scores appear high. Over the last decade this has been demonstrated convincingly in the USA, but…

Passage of the Every Student Succeeds Act (ESSA) in December 2015 signaled a new era for teacher evaluation reform. Under ESSA, states and districts have greater autonomy to design and implement teacher evaluation systems independent of federal influence. This new flexibility brings with it new responsibilities and challenges for states and…

Current special education law mandates that educators use scientifically based practices, and in addition, educators should deliver refined instruction for learners with disabilities. Applied behavior analysis, based on the premise of increasing socially significant behaviors, embodies many interventions that adhere to evidence-based teaching…

We describe an innovative automated test construction algorithm for building aligned achievement tests. By incorporating the algorithm into the test construction process, along with other test construction procedures for building reliable and unbiased assessments, the result is much more valid tests than result from current test construction…

In the wake of an increasing political commitment to evidence-based decision making and evidence-based educational reform that emerged with the No Child Left Behind effort, the question of what counts as evidence has become increasingly important in the field of science education. In current public discussions, academics, politicians, and other…

The use of value-added modeling (VAM) in school accountability is expanding. However, trying to decide how to embrace VAM can be rather nettlesome. Some experts claim it is "too unreliable," causes "more harm than good," and has "a big margin for error," while other experts assert VAM is "imperfect, but…

Schools often administer brief intelligence tests as the first step in the identification of students who are cognitively gifted. However, brief measures are often used without consideration of underlying constructs or the psychometric properties of the measures and without regard to the links between screening decisions and educational…

The growing need for more information about measuring teachers' contributions to student learning growth, particularly in nontested subjects and grades, is the impetus for this Research & Policy Brief. Although the research base in this area is disappointingly limited, the brief includes considerations and suggestions based on current models…

In this article, I specify a conceptual framework for test validity research on content assessments taken by English language learners (ELLs) in U.S. schools in grades K-12. This framework is modeled after one previously delineated by Willingham et al. (1988), which was developed to guide research on students with disabilities. In this framework…

State test scores administered for accountability purposes are regularly used to adjust instruction in nuanced ways. This is no accident--No Child Left Behind demanded that students' scores be returned quickly to teachers in order that this might be the case, and the idea of data-driven decision making continues as one way the promise of education…

The Common Core State Standards (CCSS) were created in response to the shortcomings of No Child Left Behind era standards and assessments. Among those failings were the poor quality of content standards and assessments and the variability in content expectations and proficiency targets across states, as well as concerns related to the economic…

The adoption of Common Core State Standards has increased the need for assessments capable of measuring more performance-based outcomes. This monograph brings together the current literature and resources for the development and implementation of performance assessment. The text was written as part of a project-based graduate course and has…

The No Child Left Behind Act of 2001 (NCLB, 2002) has produced an explosion of interest in the use of assessment to measure and improve student learning. Initially focused on annual state tests, educators quickly learned that results came too little and too late to identify students who were falling behind. At the same time, evidence from the…
