More and more, student assessment incorporates open-ended items. The reason is simple: these items may offer greater insights into student ability than might be gained through traditional multiple-choice assessment.

But scoring these open-ended items is often fraught with risk. The goal has to be to produce fair, repeatable results. We at Educational Data Systems have great depth of experience in designing and managing score sites. From reader training and calibration, to multiple-reader scoring models, our experience covers large- and small-scale assessments.

We have even developed a revolutionary approach to scoring that yields precise, repeatable scores while employing only one reader.
