Inside DUTYPROOF

How a NOC reference letter becomes an actionable readiness check.

Three steps. Deterministic checks. One clear record of the duties and evidence the letter does or does not contain.

The process

From job description to a readiness result, in three steps.

Enter the claimed code and title, then paste the employment letter or duties.

Step 01

Load the official claimed NOC

DUTYPROOF reads the official NOC 2021 title, main duties, and occupation exclusions for the five-digit code you enter.

Official NOC 2021 data
Step 02

Check duty evidence and letter completeness

The checker looks for concrete evidence of official duties and verifies dates, hours, salary, status, title, employer contact details, and signature.

Step 03

Return a gated verdict and correction list

Ready requires at least two evidenced official duties and a complete checklist. Otherwise, DUTYPROOF shows the gaps, exclusions, and alternate codes to investigate before submission.

Under the hood

Four checks. One explainable result.

The checker is deterministic. It does not invent duties or rely on an AI-generated legal score.

01

Duty-evidence gate

A title or generic phrase cannot produce Ready. At least two official duties need distinct, meaningful evidence in the submitted text.

02

Reference-letter checklist

Nine work-evidence fields are marked found, missing, or uncertain, with the supporting excerpt shown when one exists.

03

Exclusions and alternatives

Official occupation exclusions and the closest alternate NOCs are surfaced so a questionable code can be investigated directly.

04

Copy and template warning

Verbatim overlap with official NOC wording is flagged so the letter can describe the real work in the employer's own language.
