Investigating Suspected Plagiarism in a Folio Piece
A teacher suspects that a 900-word folio piece in the target language was not written independently. The student's earlier drafts were simple and error-prone; the final piece uses advanced subordinate clauses and several idioms not taught in class. A text-matching tool reports 18% similarity to online sources, mostly common phrases. The student claims they used an online translation tool 'only for a few sentences' and a relative helped 'check the grammar'. The school's policy requires that suspected breaches be reported to the assessment authority, which may impose a penalty. The teacher is unsure whether to report, given the 18% figure is low and the evidence is circumstantial.
1. Advise the teacher on whether the threshold for reporting is met, and what evidence should be gathered.

The threshold for reporting is not the same as the threshold for penalising. School policy requires reporting suspected breaches; the authority decides. The teacher should not decide guilt, but should decide whether there is a reasonable suspicion worth investigating.
Here there is more than the 18% figure. The relevant evidence is internal inconsistency:
- The gap between earlier drafts and the final piece in syntactic complexity and idiom range.
- The student's own admission of translation-tool use 'for a few sentences' and third-party grammar checking - both may breach independent-work rules depending on the policy wording.
- The 18% figure is weak evidence either way: common phrases inflate similarity, and translation or paraphrasing would not necessarily be detected.
The teacher should gather: draft history with dates, a short interview or written explanation from the student about specific word choices and structures, the policy wording on translation tools and outside help, and any metadata from the submission platform. Then report with the evidence bundle.
Key principle: report on reasonable suspicion, not proven guilt, and let the authority apply the penalty. The teacher's role is to document fairly, not to adjudicate.
2. The teacher is inclined to give a zero without reporting, to 'avoid stressing the student'. Assess this option.

This option is procedurally improper and unfair to the student.
- It bypasses due process. The student would receive the most severe academic penalty without a hearing, an opportunity to respond, or a documented finding. That is a natural-justice failure.
- It is inconsistent. School policy requires reporting. A teacher who penalises without reporting both exceeds their authority and breaches policy.
- It is not kinder. A zero recorded without explanation is harder to appeal than a reported matter with a documented outcome. The student loses the chance to explain the translation-tool use, which may be a minor breach rather than plagiarism.
- It sets a bad precedent for the cohort and would not survive moderation or appeal.
The correct path: report, with evidence and the student's explanation attached, and let the authority determine whether a penalty applies and what it is. If the teacher wants to reduce stress, the appropriate support is to explain the process clearly to the student, ensure they know their right to respond, and keep the matter confidential. Support and process are not in conflict; skipping process is not support.
