Probation Period Best Practices: 7 Ways to Make the First 90 Days Count
A probation period is the one stretch of employment where both sides are openly testing the fit. Used well, it turns a hiring decision into a confirmed, productive employee. Used badly, it becomes a quiet countdown that ends with a surprise exit, an avoidable dispute or a weak hire confirmed by default. For Heads of HR and founders at companies of 50 to 1,000 people, the difference is rarely the policy document. It is what managers actually do in the first weeks: the goals they set, how often they talk to the new hire and what they write down. This guide sets out seven probation period best practices that make the first 90 days count, whether the person joined from across town or from another country.

What a Probation Period Is For
A probation period gives the employer time to confirm that a new hire can do the job to the expected standard, and gives the employee time to decide whether the role and the company are what they were promised. Many companies use roughly three months, which is why HR teams talk about the first 90 days, but the permitted length, notice terms and what happens at the end vary by country, by sector agreement and by the individual contract. Some jurisdictions cap probation, some limit how often it can be extended and some give probationary staff most of the same protections as everyone else.
So the first rule is simple: check the local labour law and the employment contract before you design or apply a probation process, and take local legal advice where the rules are unclear. The practices below are management habits that work within whatever rules apply. They are not legal advice and they do not replace the contract.
Before Day One: Set the Terms
The first two practices happen before the new hire arrives. They decide whether the probation review at the end has anything solid to measure.
1. Write down what success looks like by day 30, 60 and 90
Most probation problems start with vague expectations. If a manager cannot explain what good performance looks like at the end of the period, the new hire cannot aim for it and HR cannot judge it fairly. Before the start date, agree three to five goals for the role and split them into checkpoints: what the person should understand by day 30, what they should deliver with support by day 60 and what they should handle on their own by day 90.
Keep the goals tied to the job description and the offer. A good goal is specific and observable, such as closing month-end reconciliations without rework, running a production station to the quality standard or handling a defined caseload. Avoid goals that depend mainly on other people's decisions. Our guide on how to write a job description covers how to make role expectations concrete from the start.
2. Make the probation terms clear in the contract and the welcome pack
The new hire should know from day one that a probation period applies, how long it is, what notice applies during it, when reviews will happen and who makes the final decision. Put the terms in the contract, confirm them in the welcome pack and repeat them in the first meeting. Surprises at the end of probation damage trust and, depending on the jurisdiction, can create legal risk.
For international hires, make sure the terms are explained in a language the person understands and that any permit or residence conditions linked to employment are considered before anyone talks about ending a contract. The HR compliance checklist sets out the contract and record basics every growing employer should cover.
During the 90 Days: Support and Evidence
The middle three practices are about the manager's rhythm. They give the new hire a real chance to succeed and give HR a fair record of what happened.
3. Schedule regular check-ins, not just a final review
A single review at day 85 is too late to fix anything. Book short one-to-one check-ins weekly for the first month and every two weeks after that, plus formal reviews around day 30 and day 60. Each check-in should cover three questions: what is going well, what is getting in the way and what support is needed before the next meeting.
Put the meetings in the calendar before the start date so they survive busy weeks. HR should see that they are happening; a missed check-in is an early warning that the manager, not the new hire, may be the problem.
4. Give the support the role actually needs
Probation is a two-way test. If the company does not provide the tools, training and access the role requires, a poor result says more about onboarding than about the person. Assign a buddy or experienced colleague, confirm system access in week one, and plan any training the job needs rather than expecting people to pick it up alone.
New hires from another country often need extra practical help in the first weeks: accommodation, local registration, banking, transport and getting used to a new workplace culture. Our employee onboarding checklist and the guide to onboarding foreign workers in the first 30 days set out what to prepare so that probation measures the work, not the move.
5. Document feedback as you go, fairly and factually
Write a short note after every check-in and formal review: the goals discussed, progress against them, any concerns raised, the support agreed and the next steps. Share the notes with the employee. Records should describe observable facts, such as a missed deadline or a quality issue, rather than personality labels.
Good documentation protects everyone. It helps a struggling new hire see exactly what needs to change, it gives a fair basis for the final decision and, if a decision is ever questioned, it shows a consistent process. Keep probation records with the employee file and handle them under your data protection rules.
At the End: Decide and Act
The last two practices turn the probation period into a decision. Leaving it to run out without one is the most common mistake.
6. Raise concerns early and give a fair chance to improve
If performance or conduct is off track at day 30 or day 60, say so clearly at that point. Explain the gap, agree what improvement looks like, offer the support needed and set a date to review it. A new hire who hears about a problem for the first time at the final meeting has not had a fair probation.
Treat all new hires consistently. Use the same goals framework, the same review points and the same standard of evidence for every probationer in similar roles. Structured, consistent assessment is the same principle behind structured interviews, and it reduces the risk that bias shapes the outcome.
7. Make a clear confirm, extend or exit decision on time
Before the end date, hold a final review with the manager and HR, look at the goals and the records, and make one of three decisions: confirm the employment, extend probation where the contract and local law allow it and there is a specific reason, or end the employment following the notice and procedure that apply. Confirm the decision to the employee in writing.
Do not let probation lapse by default. In many places, once the period passes without action, the employee is treated as confirmed, and a weak fit becomes a much harder conversation later. When the answer is confirm, say so warmly and set goals for the next six months; it is a strong moment for engagement and retention. Our nine employee retention practices pick up from there.
How HR Support Helps Growing Companies Run Probation Well
At 50 to 1,000 staff, probation often depends on line managers who were never trained to run it, and HR teams may not have the capacity to follow up every new hire. A simple, consistent process makes a real difference: a goals template, a check-in schedule, a standard review form and a decision step that HR signs off. If you are still building the function, see building an HR department from scratch.

Questions Employers Ask
How long should a probation period be?
Many companies use around three months, and some roles use six, but the permitted length and any limits on extension depend on the country, any sector agreement and the employment contract. Check the local labour law and take local advice before setting or changing probation terms.
Can a probation period be extended?
In some jurisdictions and contracts it can, usually once and for a stated reason, and in others it cannot. If extension is allowed, explain the specific gaps, agree what must improve and confirm the new end date in writing before the original period ends.
What should a probation review cover?
Progress against the goals agreed at the start, examples of work, feedback from the manager and colleagues, any concerns raised earlier and how they were addressed, the support given and the decision: confirm, extend or end the employment.
Do probation rules differ for international hires?
The employment law of the country where the person works normally applies, and a work permit or residence status may be linked to the job. Before deciding to end an international hire's contract, check the permit implications and any notification duties with the relevant authority or a local adviser.
