Since 1971, J&A has been measuring comparative performance and program impact in the U.S. and abroad, and has developed a reputation for results-oriented frameworks. J&A's ability for creative and flexible methodologies derives from our experience working with diverse populations and sociocultural contexts. The firm's research services are contracted for projects that require the use of comprehensive qualitative and quantitative methodologies that are adaptable to real world circumstances; appropriate sampling designs tailored to resources and local conditions; and specialized services to locate high concentrations of desired target populations.
