Authorship Continuity is one of Validate's three dimensions: Cognitive Command, Authorship Continuity and Human Factors. It looks at whether a submission reads like the same writer as the student's own writing sample.
Students upload their writing sample. It should be their own previous work, at least 500 words, separate from the assessed work and preferably recent.
There are three results: Consistent, Inconclusive and Divergent. Authorship Continuity uses no biometric or personal data.
