What a probation confirmation letter is and why it exists

A probation confirmation letter is issued at the end of a probationary period to confirm that the employee has met expectations and is being confirmed in their role. It records the date confirmation takes effect and any change in status that follows.

Its purpose is to give both sides a clear marker that the trial phase has ended on a positive note. The employee gains certainty about their continued employment, and the employer documents that the probation review was completed and the outcome communicated.

When it is used

• At the end of a successful probationary period.
• After a probation review concludes that the employee is confirmed.
• When confirmation triggers a change in notice terms or benefits.
• To close out the probation step in the onboarding process.
• Where an extended probation has now been completed.

What a well-formed probation confirmation letter includes

• Company name, address and letterhead.
• The employee’s name, job title and department.
• A clear statement that probation has been successfully completed.
• The date on which confirmation takes effect.
• Reference to any terms that change on confirmation.
• A brief, positive and factual note on the outcome.
• The date the letter is issued.
• The name, title and signature of the authorised issuer.

Common mistakes

• Issuing it when the probation review has not actually been completed.
• Being vague about the date confirmation takes effect.
• Failing to flag any terms that change on confirmation.
• Mixing confirmation with unrelated performance criticism.
• Leaving the letter undated or unsigned.
• Delaying it so the employee is left uncertain about their status.

Good practice

• Complete the probation review before issuing the letter.
• State the effective date and any changed terms clearly.
• Keep the tone positive, factual and forward-looking.
• Issue it promptly once the outcome is decided.
• Provide it as a PDF and keep the signed copy on file.
