A Practical Introduction to Classic LQAS: An Interactive Discussion about the Whys, Whens, and Hows of Applying Lot Quality Assurance Sampling

On February 22, 2024, MOMENTUM Knowledge Accelerator held a webinar on lot quality assurance sampling (LQAS), a classification method for evaluating a program to determine whether a coverage threshold has been reached. LQAS is a relatively rapid and inexpensive approach to data collection in lieu of traditional surveys used internationally and recently integrated with cluster sampling for applications in large countries. In this webinar, Joseph Valdez, a Professor of Global Health at the Liverpool School of Tropical Medicine, discusses the origins of LQAS in the 1920s; how to apply LQAS for monitoring and evaluating programs; how to select an LQAS sample size, collect the data and interpret it; and common pitfalls and things to avoid.
