By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of…

The ACTFL Assessment of Performance Toward Proficiency in Languages (AAPPL, https://www.actfl.n.d.org/assessments/k-12-assessments/aappl) assesses proficiency in 11 languages for students in grades 3 to 12 and is often used to award the Seal of Biliteracy. While arguments for the valid interpretation and uses of the AAPPL have previously been…

The high-stakes College English Test (CET), developed, administered, and reformed over the last 20 years, has received great attention in the aspect of washback on teaching and learning from previous research. Very few studies explored its consequences in the workplace domain--being used as a screening lever. This research aimed to 1) compare…

This article provides a validation framework for research on the development and use of science Learning Progressions (LPs). The framework describes how evidence from various sources can be used to establish an interpretive argument and a validity argument at five stages of LP research--development, scoring, generalisation, extrapolation, and use.…

Despite the call for an argument-based approach to validity over 25 years ago, few examples exist in the published literature. One possible explanation for this outcome is that the complexity of the argument-based approach makes implementation difficult. To counter this claim, we propose that the Assessment Triangle can serve as the overarching…
