Credit Development

The current version of STARS incorporates feedback and suggestions from hundreds of diverse stakeholders and experts (see the Technical Development Policy and archived versions of the Technical Manual). 

The STARS governance structure collectively strives to ensure that each credit is objective, measurable, and actionable. STARS is designed to incorporate the full spectrum of sustainability achievement, and upper levels of achievement represent highly ambitious, long-term goals. Therefore there are some credits for which few, if any, institutions will achieve full points currently. 

Given the diversity of higher education institutions, each STARS credit should be appropriate for most institution types. In order to accommodate this diversity, some STARS credits do not include detailed specifications but are instead flexible or open. In other cases, credits include an applicability criterion, so that the credits only apply to certain types of institutions. By following this approach, institutions are not penalized when they do not earn credits that they could not possibly earn due to their circumstances.
