Which Fourth Council? Tradition, Rubric, and the Date 29 BCE

Award 10/10: 3 for council and place, 3 for patron and date, 2 for significance, and 2 for argument. The key point is that the script matches the prescribed textbook's tradition and does not mix traditions. The phrase 'oral transmission gave way to manuscript culture' is a genuine significance point, not just a narrative fact, because it explains why the writing-down mattered for preservation and for the later commentarial tradition. I would not deduct for the absence of the specific monastery name, because the rubric asks for place, not for the monastery. Nor would I deduct for using the label 'Fourth Council' when the prescribed textbook uses Theravada numbering. If the essay were only three lines, the argument mark would fall, but as described it is coherent. The moderation note should record that full marks were awarded within the prescribed tradition, not as a claim that all Buddhist traditions number the councils identically.

Award 6/10: council and place 3/3, because the Fourth Council and Sri Lanka are correct; patron and date 0/3, because Devānampiyatissa is associated with the introduction of Buddhism to Sri Lanka in the 3rd century BCE, not with the writing down of the canon, and 129 BCE is also wrong; significance 2/2, because writing down the canon is correctly identified as significant; argument 1/2, because the narrative is coherent but the chronology is internally inconsistent. The correct council number gets credit within the first strand, but it cannot rescue the patron/date strand. The errors are not minor slips: naming the wrong king changes the historical causation, and the date is off by a century. Feedback should give the student a timeline with three anchors: Asoka's Third Council in the 3rd century BCE, the introduction of Buddhism to Sri Lanka, and the Vaṭṭagāmaṇī writing-down in the 1st century BCE.

Award 2/10 at most: 0 for council and place as the question asks about the Pali Tipiṭaka, because Kaniṣka's council is associated with Sarvāstivāda tradition and North Indian textual activity, not with the Pali canon in Sri Lanka; 0 for patron and date for the same reason; 1 for significance if the script shows some understanding that a council can be linked to textual codification, but the language claim is wrong for the Pali canon; 1 for coherence if the essay is internally consistent. In feedback, distinguish 'tradition-dependent numbering' from 'wrong answer to this question'. It is true that some traditions call Kaniṣka's council the Fourth, but the question's object is the Pali Tipiṭaka, and the prescribed textbook uses Theravada numbering. Credit the student's awareness of another tradition only if the essay explicitly contrasts the traditions; here the student asserts it as the same event, so it is a category error, not a legitimate alternative.
