Strengthening Claims-based Interpretations and Uses of Local and Large-scale Science Assessment Scores (SCILLSS)

This website houses tools, information, and resources developed as part of the Strengthening Claims-based Interpretations and Uses of Local and Large-scale Science Assessment Scores (SCILLSS) project. We pronounce that just like the word “skills”!

SCILLSS brings together a consortium of three states – Nebraska, Montana, and Wyoming – with a team of researchers and a panel of experts on validity theory, principled-design, psychometrics, and STEM education to establish a foundation for creating enhanced science assessments. Such assessments would yield scores with strong validity evidence to support score interpretation and use.

SCILLSS is funded for a 48-month period from 2017 through 2020 by an Enhanced Assessment Grant from the Office of Elementary and Secondary Education at the US Department of Education, awarded to the Nebraska Department of Education

The information below was developed for the NeSA assessment, but is still applicable for NSCAS 2018.

NeSA Science Performance Level Descriptors

Please note: The Nebraska Science Performance Level Descriptors describe three levels of mastery for specific science standards. More information about the sequence of the learning and further clarification of what students should know and be able to do can be found in the following three documents: Nebraska Science Standards – Articulated Format; Sample K-12 Science Curriculum – Articulated Format; and the Inquiry Scoring Rubric. Each of these documents may be accessed on the NDE science page.
