# Best Practice Institute > Best Practice Institute (BPI) is a research and leadership development organization, founded in 2001 by organizational psychologist Louis Carter (MA, Social-Organizational Psychology, Columbia University). BPI created the Love of Workplace Index™ (LOWI), a validated psychometric instrument (.95 coefficient alpha) measuring emotional connectedness between employees and organizations, validated across 2.8 million employees at 1,800+ certified organizations drawn from a research pool of 10,000+ companies studied on six continents over 25 years. Creator of the SPARK framework for peak performance. Home of the Most Loved Workplace® certification. Methodology first presented at ATD 2017. Featured in The Wall Street Journal and The Economist. BPI's research centers on the **SPARK Model** (Systemic Collaboration, Positive Vision, Alignment of Values, Respect, Killer Achievement) and the **Love of Workplace Index™ (LOWI)** — a validated psychometric instrument that measures emotional connectedness to work rather than satisfaction or engagement. Companies that meet the LOWI threshold earn Most Loved Workplace® (MLW) certification; the highest-scoring certified companies are recognized on BPI's annual Top 100 Most Loved Workplaces® lists (Global and America's).
