The 2026/2027 Contractor Prequal Compliance Calendar

For contractors graded in ISNetworld, Avetta, Veriforce or ComplyWorks. Every date your grade depends on, on one printable page. No email required — it's just here.

You pay each network $875–$5,000 a year for the right to be on your customers' bid lists. That access disappears when a document lapses — and most lapses are calendar events, not safety events. This is the calendar.

How to use it: print it, put a name beside every line, and load the dates into whatever your team actually looks at every week. A date without an owner is a lapse with a start date.

Part 1 — Fixed dates (same every year)

DateWhat is dueWho it applies to
Feb 1OSHA 300A summary must be posted in the workplace (stays up through Apr 30)US establishments subject to OSHA recordkeeping (29 CFR 1904.32)
Mar 2OSHA 300A electronic submission to OSHAEstablishments meeting size/industry criteria (29 CFR 1904.41)
Mar 31Avetta annual account updatereported deadline; missing it is reported to cause temporary removal from the platformAvetta-registered contractors. Confirm the date on your own account — network policy changes without notice
Q4 (now)Pre-close your injury logs: the 300 log data you certify in January becomes the 300A you post in February and the TRIR you are graded on all yearEveryone

The networks ask for your OSHA logs; the posting duty is separate law. Doing one does not satisfy the other.

Part 2 — Annual, anchored to your own dates

ItemThe trap
OSHA 300/300A logs — current + prior 3 yearsIt is a rolling 4-year window. Every year the oldest year drops off and the new year must be added. An old upload does not "stay done."
EMR letter (prior 3 years)Issued by your workers'-comp carrier after renewal. The most common failure is filing the new letter into the wrong year's slot — the score damage looks like a missing document.
TRIR / DART submissionDerived from your OSHA logs — an error upstream propagates here, and hiring clients set the pass threshold, not the network.
Written program (RAVS) annual reviewISN expects a documented annual management review of each program. An unchanged, unreviewed program decays your score even though "nothing changed."
Training records / licences / TPA renewalsEach has its own expiry; each needs an owner.

Part 3 — Driven by your insurance policy terms

ItemThe trap
COI — general liabilityLimits, endorsements and additional-insured wording are set per hiring client, not per network. A renewal that drops one endorsement fails one client silently.
COI — workers' compensationRenewal follows the policy term, not the calendar year.
COI — commercial autoSame. The certificate expiring — not the policy — is what the network sees.

Ask your broker for renewal certificates 30 days before each policy term ends, and send them to the networks the day they arrive.

Part 4 — The ongoing one everyone misses

The network notification inbox. Requirement changes, RAVS audit requests, and action items land in whatever email address was registered years ago — often a person who has since left. Compliance firms report the same pattern repeatedly: the request sits unread, and the grade drops months later.

Decide today whose job that inbox is, and what happens to it when they take vacation or resign.

The worksheet works — until the person maintaining it changes jobs. PrequalGuard is a monitoring service that watches these dates and your network notification inbox so nothing lapses unnoticed. We're taking our first five pilot contractors.
