A pre-flight checklist for generating certificates in bulk

Why certificates deserve extra care

Certificates are the batch documents people keep, frame, and attach to job applications. Errors are visible for years, and reprints cost trust as well as time. The checklist below is what experienced program teams verify before pressing generate.

The data checklist

• •Names exactly as learners registered them — including capitalization. Fix casing in the source data, not by hand afterwards.
• •One unique certificate number per row, from a sequence you control and record.
• •Completion dates that match the cohort's actual end date.
• •Grades only if your program publishes them; an empty optional field renders cleanly.
• •A verification URL per certificate if you use QR codes — and a verification page that is already live.

The layout checklist

• •Preview the longest name in the batch, not the shortest. Auto-shrink handles long names, but check it still looks dignified.
• •Verify the QR code scans from a printed sample, not just on screen.
• •Check the output filename pattern produces distinct, meaningful names — certificate-{{student_name}} collides when two students share a name; adding the certificate number never collides.

Generate a pilot batch first

Generate five certificates locally, print one, scan the QR, and have someone who did not build the template review it. Only then run the full cohort. If a few rows fail validation, generate the valid ones and retry the corrected rows afterwards — a partial batch today usually beats a perfect batch next week.
