Quantitative Methods for Policy Research

Under its research program on Quantitative Methods, the Statistics for Evidence-Based Policy and Practice, or STEPP, Center seeks to serve the practitioners and policymakers by developing and promoting state-of-the-art methods for researchers, especially in education and the applied social sciences. It seeks to generate strong evidence on research designs, synthesize and interpret results of multiple studies, and translate findings to inform policy and practice. The STEPP Center was founded in 2019 and evolved from IPR’s Q-Center.

A Message From Larry Hedges, Program Chair and STEPP Co-Director

We launched the Q-Center at IPR in 2006 to take advantage of a critical mass of scholars at the forefront of evidence-based research on social policy issues. Today, we seek to build on our foundational work by launching the STEPP Center to further develop and assess methods to generate, synthesize, and translate evidence to improve policy and practice.

Building an ‘Evidence-Based Ecosystem’

The STEPP Center believes in “a scientific approach to transform the social world and a practice-driven approach to advance science,” and says its goal is to “improve lives through methodological innovation in research.” IPR statistician and co-founder Elizabeth Tipton says interdisciplinary cooperation will be key to STEPP’s overall contribution to the policy sphere.
