Under subcontract to Office Remedies, Inc. (ORI), IMPAQ International assisted the Bureau of Labor Statistics (BLS) and its Quarterly Census of Employment and Wages (QCEW) program to design forms to collect data on environmental sector business activity at individual establishments. The project helped BLS to better understand, collect, and produce economic statistical data on environmental sector industry employment in the U.S. The project consisted of two phases: Phase I included a response analysis survey (RAS) of 200 establishments to gain an understanding of key research questions and understand the data collection environment. Phase II included the conduct of cognitive interviews and the subsequent design of an initial data collection form followed by four waves of forms revision and testing. Findings from this formative research assisted in the design of data collection forms that were used in a large annual survey of 120,000 business establishments. At the end of the project, the project team prepared a final report documenting the recommendations from the study.
