The need for scientifically based research has never been greater. The growing role of research in decision making, combined with federal program funding requirements that require scientifically based research support, are two key reasons for this. At SEG we are committed to providing sound research data to support decision making. Whether your needs center on program evalaution, product effectiveness, market research, or assessment validation, let SEG help you design and conduct research to meet those needs.

Scientifically-based research carried out by a qualified third party is required for federal funding of product and service purchases under NCLB.

SEG provides a full array of implementation services including recruitment and site contact, data collection, data analysis and reporting. From randomized trials to field research, we can help you get the information you need. We provide a range of data analysis services including scanning, key entry and data management. Our analyses range from simple frequencies and crosstabls to complex multivariate models. We are known for the quality of our reporting--clear, concise, and sensitive to the political context.

Much like a building's foundation, research must be based on a clear, well-constructed research design. SEG can help you design qualitative and quantitative research studies to meet your specific goals. We are specialists in experimental and quasi-experimental designs and the assessment of multiple outcomes using tests, surveys and observation. Let our nearly 30 years of experience in evaluation help guide you.

We provide a full range of psychometric analysis services using both classical and IRT based methods. Our services include item analysis, item bank calibration, standard setting and test validation. For example, we recently developed a grade 3-8 computer adaptive math assessment scored on a vertical scale, and helped a major publisher develop multiple forms of an ELL test linked to a common scale.
