Great hires fail because of bad onboarding, not bad hiring. Companies with strong onboarding improve new-hire retention by 82% (Brandon Hall Group). This checklist covers everything from the offer letter to Day 90 — steal it, customize it, use it Monday.
Before Day 1
- Signed offer letter and employment agreement filed
- I-9 employment eligibility verification prepared (Section 1 due Day 1)
- W-4 and state tax forms ready
- Workstation, logins, and equipment set up and tested
- Welcome email sent: start time, parking, dress code, first-day agenda
- Buddy/mentor assigned
Day 1
- Warm welcome — tour, introductions, lunch with the team
- HR paperwork: I-9 Section 1, W-4, handbook acknowledgment
- Review role, goals for the first 90 days, and how success is measured
- Systems access confirmed working
- End-of-day check-in: “What questions do you have?”
Week 1
- 1:1s scheduled with key teammates and stakeholders
- Product/service and customer training completed
- First small win assigned — something shippable in week one
- Benefits enrollment walkthrough
Days 30 / 60 / 90
- Day 30: feedback conversation — what’s working, what’s confusing
- Day 60: progress against 90-day goals, training gaps addressed
- Day 90: formal review — confirm the hire, set next-quarter goals
The 3 onboarding mistakes that kill retention
- Paperwork as onboarding. Forms are admin, not onboarding. The job is making someone effective.
- No 90-day goals. “Figure it out” is not a plan. Write down what good looks like.
- Silence after week one. Check in at 30/60/90 or small problems become resignations.
