Product Development

“More pertinent to this [evaluation of OPO], of course, is the Education branch’s long history in conducting both formative and summative evaluations for its own formal/informal science education products and services.  Sound evaluation tools and techniques have been employed from the earliest days of the branch’s work in developing, reviewing, revising, releasing and continually monitoring its products and services.”
– Comprehensive Evaluation: Cornerstone Evaluation Associates LLC

Every formal and informal educational product or program produced by STScI is standards-based, field-tested and evaluated for impact. We have a well-defined and rigorous development model.

Development and Evaluation Model


STScI carries out an ongoing program of interviews and surveys of over 1400 representative venues (including colleges, school districts and science centers) that use STScI’s education products, giving evidence that these materials remain useful and effective.
