The Love of Workplace Index™ (LOWI) is a validated psychometric instrument developed by Best Practice Institute (BPI) and Louis Carter to measure emotional connectedness between employees and their organization — the structural conditions that predict retention and performance.
Unlike engagement or satisfaction surveys, which measure how employees feel at a moment in time, LOWI measures whether the conditions for sustained love of work exist inside the organization. It rests on five dimensions — the SPARK framework — Systemic Collaboration, Positive Vision for the Future, Alignment of Values, Respect, and Killer Achievement.
LOWI has been validated across more than 2.8 million employees at 1,800+ organizations spanning six continents, with a coefficient alpha reliability score of .95. The instrument is the scientific foundation of the Most Loved Workplace® certification: companies that meet the LOWI threshold earn certification, and the highest-scoring certified companies are recognized on BPI's annual Top 100 Most Loved Workplaces® lists.
LOWI is administered to employees as a structured survey and analyzed using machine-learning-powered sentiment models that benchmark each organization against the validation pool of 10,000+ companies BPI has studied over 25 years. The output is not a single score but a diagnostic — a SPARK profile that shows where the organization is structurally strong and where it must intervene to retain its people.
Research from certified companies shows that 92% of applicants cite the certification as a reason for joining and that certified companies see meaningfully higher retention. Those outcomes are not artifacts of marketing — they are the downstream signal that the conditions LOWI measures are real, repeatable, and improvable.
