StatsQUAL® is a gateway to library assessment tools that describe the role, character, and impact of physical and digital libraries. Through StatsQUAL®, libraries gain access to a number of resources that are used to assess library's effectiveness and contributions to teaching, learning, and research. StatsQUAL® presents these tools in a single powerful interactive framework that integrates and enhances data mining and presentation both within and across institutions. StatsQUAL® includes instruments and data such as LibQUAL+®, DigiQUAL®, and MINES for Libraries®, as well as a growing dataset of survey results.

StatsQUAL® operates under the leadership of the Association of Research Libraries (ARL), which has a long-standing role in the development, testing, and application of performance measures, statistics, and management tools. Using traditional benchmarks as well as new models for measurement and evaluation, StatsQUAL® addresses the urgent demand for libraries to demonstrate outcomes and contributions.
