Applying a five-category deduction scheme to one paragraph
You are marking a 5-mark editing task. The scheme reads: deduct 0.5 for each error falling in five categories only - subject–verb agreement, tense, article, preposition, sentence fragment; spelling, punctuation and word-choice errors are noted in the margin but not deducted; maximum deduction 3 marks; no negative marks. The candidate's paragraph reads:
Last week our school celebrate its annual day. The principal, along with two teachers, were invited to the district office same day, so the programme begin at eight instead of ten. Many parents which had taken leave reached late. A group of Class XI students were waiting at the gate since seven; they had practise the chorus for weeks. Because the sound system failed twice. The audience waited, and the choir sang without music.
You have four minutes to mark this script and must also give the candidate one line of feedback.
1. Classify each error as one of the five deductible categories or as non-deductible, then compute the final mark.
Read the worked answer
| Error | Category | Deduction |
|---|---|---|
| celebrate → celebrated | tense | 0.5 |
| were invited → was invited | subject–verb agreement | 0.5 |
| same day → the same day | article | 0.5 |
| begin → began | tense | 0.5 |
| which → who | relative pronoun - not listed | 0 (margin note) |
| had practise → had practised | tense/verb form | 0.5 |
| "Because the sound system failed twice." | sentence fragment | 0.5 |
Deductible total: 6 × 0.5 = 3.0, which is exactly the cap. Final mark: 2/5.
Two points to record for consistency: if you rule that "had practise" is word form rather than tense, you are left with five errors and 2.5 deducted, giving 2.5/5 - the cap means the disputed item is worth only half a mark, so choose one reading and apply it to every script in the bundle. Also note that no preposition error occurs here; the scheme's five categories are a filter, not a checklist to be filled.
2. Justify the "were invited" decision, and explain why a weaker marker might wrongly deduct for "which".
Read the worked answer
"were invited": the grammatical subject is The principal, singular. "Along with two teachers" is a parenthetical addition, not part of a compound subject - unlike "the principal and two teachers", which would take a plural verb. The verb therefore agrees with principal: was invited.
A weaker marker sees "two teachers" immediately before the verb and applies proximity instead of structure. This is one of the most common misjudgements in agreement marking, and it produces a deduction the script does not deserve.
"which": the marker's ear says "people take who", so the deduction feels obvious. But the scheme lists five categories, and relative-pronoun choice is not among them. Deducting here enforces a rule the scheme does not contain, and since some markers will and some will not, it makes scripts from the same centre incomparable. If the department believes the category should be penalised, that must be settled before marking begins and applied to the whole bundle - not decided script by script.
3. Rewrite the fragment so the paragraph reads correctly, and state whether doing so reverses the deduction.
Read the worked answer
Rewrite: "The audience waited patiently, and the choir sang without music, because the sound system failed twice."
This works because "Because the sound system failed twice" is a subordinate clause with no main clause attached; joining it to the preceding main clause restores the missing relationship. An alternative, "The programme was disrupted because the sound system failed twice", is also correct but loses the audience-and-choir detail, so the first is preferable.
The deduction is not reversed. The half mark was for producing a fragment in an editing task; the rewrite is the feedback, not a re-mark. Enter the corrected sentence in the margin only, and keep the score at 2/5.
Feedback line: "You found the fragment but joined it with a full stop; check every sentence for a main clause before you move on." That tells the candidate both what went wrong and how to catch it next time, which is more use than the mark alone.
