Calipers: Simulation-Based Assessments

What is the Calipers Project?

The first Calipers project, led by the Center for Technology in Learning at SRI International from fall 2004 to spring 2007, used technology-based simulations to develop and study a new generation of assessment systems. Working with the Concord Consortium and WestEd, this two-year demonstration project studied the potential of technology- and simulation-based assessments to provide high-quality evidence of complex performances in science tests for both accountability and formative goals. The first Calipers project was transferred to WestEd in spring 2007, and under a recently awarded NSF Grant, a second Calipers project is continuing under the leadership of Edys Quelmalz at Wested.

Assessments were developed key areas of middle and high school science: forces and motion (physical science) and populations and ecosystems (life science).
