This open access book describes and reviews the development of the quality control mechanisms and methodologies associated with IEA’s extensive program of educational research. A group of renowned international researchers, directly involved in the design and execution of IEA’s international large-scale assessments (ILSAs), describe the operational and quality control procedures that are employed to address the challenges associated with providing high-quality, comparable data. Throughout the now considerable history of IEA’s international large-scale assessments, establishing the quality of the data has been paramount. Research in the complex multinational context in which IEA studies operate imposes significant burdens and challenges in terms of the methodologies and technologies that have been developed to achieve the stated study goals. The demands of the twin imperatives of validity and reliability must be satisfied in the context of multiple and diverse cultures, languages, orthographies, educational structures, educational histories, and traditions. Readers will learn about IEA’s approach to such challenges, and the methods used to ensure that the quality of the data provided to policymakers and researchers can be trusted. An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data.

Validity is the hallmark of quality for educational and psychological measurement. But what does quality mean in this context? And to what, exactly, does the concept of validity apply? These apparently innocuous questions parachute the unwary inquirer into a minefield of tricky ideas. This book guides you through this minefield, investigating how the concept of validity has evolved from the nineteenth century to the present day. Communicating complicated concepts straightforwardly, the authors answer questions like: What does ′validity′ mean? What does it mean to ′validate′? How many different kinds of validity are there? When does validation begin and end? Is reliability a part of validity, or distinct from it? This book will be of interest to anyone with a professional or academic interest in evaluating the quality of educational or psychological assessments, measurements and diagnoses.

The literature on issues of the reliability and validity of objective and performance assessments in vocational education and training was reviewed and synthesized to develop guidelines for procedures to enhance reliability and validity. The review established the following facts: (1) validity is determined largely through inferences made by both the task developers and users; (2) the assessor's intention is an essential component of validity; (3) although "authenticity" provides evidence of the face validity of workplace assessments, additional evidence of content, criterion, construct, and consequential validity is needed before assessments can be called valid; and (4) an assessment's reliability is an estimate of the measurement task's accuracy or precision as a measurement instrument. The method of gathering evidence and characteristics of the candidate were identified as common sources of error associated with both objective and performance assessment. The following additional sources of error were associated with performance assessment: characteristics of the assessor; context of the assessment; and range and complexity of the task(s). It was concluded that each of these sources of error must be controlled throughout the assessment and that establishing clear task specifications (including evidence to be collected and decision-making rules) will increase reliability.

The internal validity of a study reflects the extent to which the design and conduct of the study have prevented bias(es). One of the key steps in a systematic review is assessment of a study's internal validity, or potential for bias. This assessment serves to: (1) identify the strengths and limitations of the included studies; (2) investigate, and potentially explain heterogeneity in findings across different studies included in a systematic review; and (3) grade the strength of evidence for a given question. The risk of bias assessment directly informs one of four key domains considered when assessing the strength of evidence. With the increase in the number of published systematic reviews and development of systematic review methodology over the past 15 years, close attention has been paid to the methods for assessing internal validity. Until recently this has been referred to as “quality assessment” or “assessment of methodological quality.” In this context “quality” refers to “the confidence that the trial design, conduct, and analysis has minimized or avoided biases in its treatment comparisons.” To facilitate the assessment of methodological quality, a plethora of tools has emerged. Some of these tools were developed for specific study designs (e.g., randomized controlled trials (RCTs), cohort studies, case-control studies), while others were intended to be applied to a range of designs. The tools often incorporate characteristics that may be associated with bias; however, many tools also contain elements related to reporting (e.g., was the study population described) and design (e.g., was a sample size calculation performed) that are not related to bias. The Cochrane Collaboration recently developed a tool to assess the potential risk of bias in RCTs. The Risk of Bias (ROB) tool was developed to address some of the shortcomings of existing quality assessment instruments, including over-reliance on reporting rather than methods. Several systematic reviews have catalogued and critiqued the numerous tools available to assess methodological quality, or risk of bias of primary studies. In summary, few existing tools have undergone extensive inter-rater reliability or validity testing. Moreover, the focus of much of the tool development or testing that has been done has been on criterion or face validity. Therefore it is unknown whether, or to what extent, the summary assessments based on these tools differentiate between studies with biased and unbiased results (i.e., studies that may over- or underestimate treatment effects). There is a clear need for inter-rater reliability testing of different tools in order to enhance consistency in their application and interpretation across different systematic reviews. Further, validity testing is essential to ensure that the tools being used can identify studies with biased results. Finally, there is a need to determine inter-rater reliability and validity in order to support the uptake and use of individual tools that are recommended by the systematic review community, and specifically the ROB tool within the Evidence-based Practice Center (EPC) Program. In this project we focused on two tools that are commonly used in systematic reviews. The Cochrane ROB tool was designed for RCTs and is the instrument recommended by The Cochrane Collaboration for use in systematic reviews of RCTs. The Newcastle-Ottawa Scale is commonly used for nonrandomized studies, specifically cohort and case-control studies.

It is an honor to write the foreword for The Reliability and Validity of the School Success Profile (SSP). The SSP stands alone as one of the truly excellent, empirically validated, comprehensive, and standardized measurement tools for schools. As a measurement instrument, the SSP offers a measure of individual student risks and assets across multiple dimensions, capturing school, neighborhood, and community contexts. I first became interested in this measure because it offered a useful way to identify and measure student assets and strengths. Since that time, I have personally used this measure in my own research projects on solution-focused therapy, and I have found the SSP to be an excellent assessment and outcome measurement tool for use in both research and applied settings. Over the past 13 years, Gary Bowen and colleagues at the University of North Carolina's School of Social Work have developed the School Success Profile (SSP), a comprehensive assessment instrument. This standardized measure has 220 items and represents one of the best measures in the field of school and youth measurement for assessing individual students on social environment and individual adaptation across 22 dimensions. From its very inception as an outcome assessment and intervention planning tool, Bowen and colleagues and their funders have made a commitment to the ongoing psychometric and empirical development of the SSP for use in secondary and elementary schools. Validity and reliability studies on the SSP have repeatedly shown acceptable psychometric characteristics as both a research measure and as a developing clinical practice tool, but there has not been an easy way for practitioners to evaluate this information. The introduction of this monograph, The Reliability and Validity of the School Success Profile (SSP), serves as a technical manual for use of the measure and summarizes a large study on the SSP's psychometric characteristics. This manual is further evidence of the commitment of Bowen and colleagues to the long-term development of this measure. The current monograph has most everything one would expect in a technical manual for a measurement instrument, and it also provides added online resources. The manual is well organized and provides a summary of the basic validity and reliability information as well as helpful content on scoring, administration, and limitations of the measure. It also provides some very useful practical guidelines for how and when to use the measure in a school. Most importantly, the monograph briefly summarizes the historical and theoretical development of the measure, and it provides concise details on the recent validity and reliability studies in an easy-to-read format that is straightforward for practitioners to evaluate. The manual further highlights the clinical utility of the measure by demonstrating how the scoring system is both student- and practitioner friendly, providing an example of an uncomplicated plot of scores that are color coded as green for strengths, yellow for cautions, or red for risks. The color coding scheme has considerable face validity and clinical utility and, as the manual recommends, this makes it possible for the results to be discussed with youths and other participants, for the purposes of verifying validity and intervention planning. The study reported in the manual provides continuing confidence in the reliability and validity of the SSP for intervention and outcome measurements, and it serves as an accountability document for practitioners who may be using the SSP. Although the manual appears to simplify data for practitioners, it does not neglect to provide a Web site for other studies and technical details that are made available online. This adds to the user friendliness of the manual for researchers and psychometricians interested in studying the measure and its strengths and limitations in more critical detail.

Making Classroom Assessments Reliable and Valid by Robert J. Marzano will convince you that classroom assessments should become the primary method for formally measuring student learning over other types of assessment in education. Read about the key advantages of classroom assessments over interim, end-of-course, and state assessments in how to assess student learning and measure growth over time. Marzano also addresses the validity and reliability of classroom assessments and how to improve those metrics before bringing them to their rightful place in K-12 assessments. This book outlines how to revamp validity and reliability to match technical advances made in classroom assessment, instead of matching large-scale assessment's traditional standards. Using this book, teachers, schools, and districts can design classroom assessments that are equally if not more reliable and valid than traditional large-scale assessments. How this book will convince you to use classroom assessments: Consider the history of large-scale assessments in US education and the purpose of standardized testing. Inspect the importance of and future role of classroom assessment. Explore the three mathematical models of reliability, as well as the three major types of validity. Understand the principles of assessment for learning and the importance of measuring students' individual and comparative growth. Use the provided formulas to create classroom assessments that match traditional interim or end-of-year assessments in reliability and validity. Contents: Introduction: The Role of Classroom Assessment Chapter 1: Discussing the Classroom Assessment Paradigm for Validity Chapter 2: Designing and Scoring Parallel Assessments Chapter 3: Discussing the Classroom Assessment Paradigm for Reliability Chapter 4: Measuring Growth for Groups of Students Chapter 5: Transforming the System Using the New Classroom Assessment Paradigms Appendix
