How is the C-E-R scored?

The CER grading critera with examples are found in our Teacher Guide linked here: Teacher Guide.

Our automated scoring algorithms were built using student data and were developed to ensure they match with human scorers. The scoring focuses on science concepts, not student spelling, grammar, or punctuation. For more information on how the algorithms were validated, please see our Research Papers.
