The CLEAR Policies and Procedures document describes all aspects of CLEAR operations, including the process for conducting Systematic Evidence Reviews, an overview of CLEAR review types, the different types of studies included in CLEAR, CLEAR's searchable study database, and how to contact CLEAR.
This document provides answers to frequently asked questions about CLEAR and its content, including both how reviews are conducted and how to search the site.
Causal Evidence Resources
CLEAR reviews causal studies in a number of labor-related topic areas and assigns a rating indicating the strength of their causal evidence. This document provides the CLEAR evidence criteria for rating causal studies. A companion addendum provides additional examples of how to apply the guidelines to rate the strength of causal evidence.
CLEAR utilizes the Study Review Guide for Causal Reviews (SRG) to review causal studies. The SRG captures important information about the study, including the setting, characteristics about the sample, data sources, and key findings. CLEAR reviewers enter information from the study into the SRG to assign a causal evidence rating. Each SRG undergoes a quality assurance review by a senior CLEAR staff member.
This document explains how CLEAR assigns causal evidence ratings to describe intervention effectiveness. Intervention effectiveness ratings rely on multiple individual study causal evidence ratings. Ratings of intervention effectiveness indicate the number of studies with favorable evidence.
Topic tags indicate the topic or subject of the intervention, program, or policy being studied. Topic tags are used to categorize the database and enable searches. CLEAR reviewers assign at least one tag to each study.
This document explains how CLEAR conducts rapid evidence reviews to quickly summarize evidence on relevant programs and potentially promising strategies that can help policymakers, program administrators, government agencies, and others make evidence-based decisions in response to pressing labor issues, such as the COVID-19 pandemic.
Implementation and Descriptive Evidence Resources
CLEAR reviews selected reports that describe a program or policy's implementation process or measure implementation inputs and outputs to assess a planned program's fidelity. Reviewers utilize the guidelines to assess the study's technical qualities and to describe the findings for a CLEAR profile. These guidelines support consistency across reviews.
CLEAR utilizes the Implementation Study Review Guide (I-SRG) to review implementation studies. The I-SRG includes three review stages to ensure relevant information is included, such as prescreening information, key study and intervention features, technical details, and findings. Each I-SRG undergoes a quality assurance review by a senior CLEAR staff member.
CLEAR reviews quantitative descriptive studies in a number of labor-related topic areas and describes features of the studies. These are studies that use statistical techniques and other quantitative approaches, but do not examine effectiveness. The document includes a reivew checklist. Reviewers utilize the guidelines to assess the study's technical qualities and to describe the findings for a CLEAR profile. These guidelines support consistency across reviews.
