Enable safe use of AI
in assessment
Validate original student writing
— a new approach to academic integrity.
Student authenticity score
We analyze multiple aspects of a submission to measure the level of original student writing. This gives us evidence to calculate a student authenticity score — the strength of the "student voice."
The instructor can judge whether the level of AI writing-assistance is acceptable and whether the submission is valid for assessment. Additionally, the instructor can use the result in a learning process to foster academic integrity to see more original work and encourage critical thinking.
The absence of original student writing can also be evidence of contract cheating.
Four tests — telling a story of each submission.

Verified text — Linguistic analysis
Comparing the submission with the student’s unique linguistic fingerprint.
Human text — Perplexity analysis
Measuring the perplexity of the text to determine if it is human written (opposite of AI detection).
Free text questions — Simulation of oral exam
Confirming the student’s knowledge by asking simple questions from their submission.
Cloze questions — Testing writing style
Testing the student’s ability to fill in missing words from their own sentences.

Validation, not detection
Norvalid's Authorship Validation method searches for evidence of the student's writing.
Our method can be combined with traditional plagiarism detection, which is searching for evidence of others' writing.
By confirming original student writing, we also confirm the absence of ghostwriting and plagiarism.
