Track probation period end date.
Probation is a fixed window with a decision at the end, and the useful figures are how much of it is gone and when the next formal conversation falls. Spacing checkpoints evenly across the period — dividing by one more than the number of reviews so the last one sits before the end — means the final review is never the first time concerns are raised. The objectives-per-month figure shows whether the remaining time is enough to evidence what was agreed.
Probation progress and checkpoints
Total days = months x 30.44; elapsed share = elapsed / total x 100; checkpoint interval = total / (checkpoints + 1); next checkpoint = next multiple of the interval minus elapsed
Probation rules, permissible length, notice during probation and dismissal protections vary significantly by jurisdiction and contract. Seek employment advice for decisions that depend on them.
Three to six months for most professional roles, occasionally twelve for senior or regulated positions. Some jurisdictions cap the maximum length or require it to be proportionate to the role.
Often yes, if the contract provides for it and the extension is communicated before the original period ends. An extension applied retrospectively is usually unenforceable.
Bring written evidence against each agreed objective and ask directly whether anything would prevent confirmation. A final review should confirm a conclusion already understood, never introduce it.
