Compute, record and proofread data

The task, from O*NET: Compute, record, and proofread data and other information, such as records or reports.

Typical length 38 minutes. Time split: documents 50%, systems 50%. About 308,701,198 hours a year of desk work across the US go to this task.

Passes, one attempt by Claude Fable 5.1. The rubric was written 2026-10-01 03:25 UTC, before the attempt (2026-10-01 03:41 UTC); the grade came last (2026-10-01 03:48 UTC).

One attempt at one task on one date, with constructed material: it is not a statement that the job, or this task in a given workplace, can be done by AI. The rubric, the attempt and the grade were made by the same model in one session, in that order; a person's check of a sample of grades will be published beside them.

The brief

You are the office clerk at Linden Street Dental Group. The office manager asks you to finish the September supplies reconciliation before Thursday's meeting: take the supply log (quantities received, transcribed below) and the three vendor invoices, compute each line's extended cost, total by vendor and by category, proofread the log against the invoices, and list every discrepancy with the figure you believe is correct and what should happen next. The invoices are the source of truth for prices; the log is the source of truth for quantities received. Do not alter invoice figures; flag them. Deliver a clean table and a short discrepancy note for the manager.

The material

Constructed for this example; the names, figures and documents are invented.

INVOICES
Crestline Dental Supply, invoice 88412, September 9: gloves medium 24 x $9.85 = $236.40; gloves large 12 x $9.85 = $118.20; prophy paste 10 x $14.20 = $142.00; sterilization pouches 15 x $11.40 = $171.00; face masks 30 x $8.60 = $258.00; paper towels 4 x $29.90 = $119.60. Invoice total $1,045.20.
Brightway Materials, invoice BM-20931, September 16: composite A2 18 x $38.00 = $684.00; composite A3 8 x $38.00 = $304.00; bonding agent 4 x $62.50 = $250.00; impression material 6 x $54.00 = $324.00. Invoice total $1,562.00.
Northgate Pharma, invoice 55107, September 22: lidocaine cartridges 6 x $41.75 = $250.50; topical gel 3 x $17.30 = $51.90. Invoice total $320.40.

The rubric, written before the attempt

1. Every line's extended cost is computed with the invoice price and the log quantity, and the arithmetic is right. Evidence: Twelve lines; for example gloves medium $236.40, prophy paste $142.00 at $14.20, impression material $378.00 at the log's quantity of 7 (or $324.00 at the invoiced 6, with the quantity gap flagged).
2. Totals by vendor and by category are right and reconcile to one grand total, with the basis stated where the quantity gap changes it. Evidence: Crestline $1,045.20; Northgate $302.40; Brightway $1,616.00 on the log's quantities or $1,562.00 on the invoice's, said which; categories add to the same grand total.
3. All three discrepancies are found: the log's prophy paste price ($12.40 against the invoice's $14.20), the impression material quantity (7 logged, 6 invoiced), and the Northgate invoice total ($320.40 stated against $302.40 computed). Evidence: Each named with both figures.
4. Each discrepancy carries a proposed figure or next step without rewriting the invoice: use $14.20; verify whether a seventh pack arrived unbilled or was miscounted before paying; ask Northgate for a corrected invoice or pay the computed $302.40. Evidence: A handling line per discrepancy; invoice figures left as stated and flagged.
5. The deliverable is a clean table (item, quantity, unit price, extended cost, vendor, category) and a short note for the manager. Evidence: The table has those columns; the note is a few lines.
6. No arithmetic error anywhere in the table or the totals. Evidence: A check of every extended cost and every total.

DISCREPANCY NOTE FOR THE MANAGER

1. Line 3, prophy paste. The log shows $12.40 a jar; Crestline's invoice bills $14.20. The invoice price is used above ($142.00). The log's figure looks like a transcription error, and nothing is paid differently.

2. Line 11, impression material. The log records 7 packs received; Brightway invoiced 6 ($324.00). Either a seventh pack arrived unbilled or the receiving count is wrong. I carried 7 at $54.00 ($378.00) because the log is our record of what came in, but we should count the shelf before paying: if 7 are on hand, expect a $54.00 invoice from Brightway or tell them; if 6, correct the log, and the Restorative total falls to $1,562.00 and the grand total to $2,909.60.

3. Northgate invoice 55107. The two lines add to $302.40 ($250.50 plus $51.90), but the invoice states a total of $320.40, which is $18.00 too high. Ask Northgate for a corrected invoice, or pay $302.40 against the two lines. I have not changed the invoice figure, only flagged it.

Everything else on the log agrees with the invoices.

The grade

Graded 2026-10-01 03:48 UTC against the rubric above, by the same model.

Overall: passes. The three planted discrepancies were found and handled in the way the brief asked: invoices flagged, not rewritten, and the quantity gap carried on the log's basis with the alternative stated. The attempt did not compute the per-category figures under the alternative basis, which the rubric did not require.

How the examples are made and graded: the method. Every task of this job, with its length and when it comes within reach: Office Clerks, General.
